Each Subscriber Identity Module is programmed with specific identification features for a unique user, allowing the device that contains a module to be used for such things as online banking and purchasing that require a secure means of identification. They can be swapped between other

GSM devices, so the Subscriber Identity Module owner isn't confined to a single device.

Teletrac will use the SIM Cards as a quick way to move specific programming information from one location unit to another. The SIM Card will contain information such as location schedules, landmarks, service reminders etc. When the hardware of a locator unit goes bad an installer will replace the hardware and take the SIM Card from the broken device and place it in the new device. This will move all the programmed information and alleviate the need to reprogram units.

P RISM TM2 F UNCTIONALITY

Teletrac, Inc. - Prism TM2 Information and Installation Guide

The Prism TM2 is designed to behave the same way as the VLU plus

unit and have the same features available. However, the Prism TM2 is not as programmable as the VLU plus

. Instead of having a script, the Prism TM2 has a hard coded set of instructions that can have some small configuration changes. Below is a list of how the unit will act by default; changes to the configuration will be a future implementation. See Unit Four for a description of the features available, as well as, a feature comparison between all the Teletrac units.

P RISM TM2 F EATURES D EFINED

The Prism TM2 has many new features in addition to the features seen in the Standard units.

Below is an explanation of these features.

Long Inbound Messaging

Long Inbound Messaging (LIM) is a feature that allows the Prism TM2 to send alphanumeric form fill messages that are longer than five form characters, up to 197 of free text or field characters.

With LIM comes a larger amount of applications such as bar code readers, credit card readers, data terminals and driver identification can be supported. LIM requires a messaging terminal and optional keyboard.

Scheduled Locations

A vehicle is able to send locates to the dispatcher without the workstation sending a request.

This means a vehicle can automatically send in a locate at the end of a designated amount of time or distance. Now, if a vehicle is in motion, you will get locates at a given interval no matter if the ignition is on or not. Further, the vehicle will send in located at a given interval if the ignition is on no matter if the vehicle is moving or not (i.e. idling). By having location schedules in the Prism

TM2 , the unit changes it’s own schedule through the condition of the

Note: Scheduled Locations vehicle and doesn’t require a message with a status change be sent is not dependant upon what time of day it is, only what condition the vehicle is in.

1622-0300 B2-5 05 2006 4

Teletrac, Inc. - Prism TM2 Information and Installation Guide to the workstation in order to change it’s location schedule. Also, since a location schedule can also be stopped due to the vehicle’s condition ( Ignition off and Not moving ), a lot of unnecessary locates and locations requests are eliminated thereby, reducing airtime usage.

Teletrac, Inc. - Prism TM2 Information and Installation Guide

In Motion detection

The Prism TM2 will be capable of detecting when the vehicle is stationary or moving with +/- 1 mph accuracy. Upon detecting either of the events, the Prism TM2 can send messages or begin timers. The ultimate goal of this feature is to eliminate locations unless the vehicle is moving or the ignition is on, which will save location units. (Min. detectable speed is 3 mph due to jitter)

This feature can be used to perform several capabilities currently being done by Fleet Director but without the high rate of location requests and possibility of missed information. For example, this feature can be used as a security feature to determine if a vehicle is parked where is supposed to be without the use of Landmarks or Exception Conditions and the workstation does not have to locate the vehicle every 15 minutes to see if it is still stationary. With this feature the Prism TM2 will identify that it is stationary and send a message upon detecting movement. Once in motion, the Prism TM2 can send locates on a regular bases to keep the workstation up to date. This prevents the problems of unnecessary locations and status change requirements to get a different location. Since the Prism TM2 locates itself, there is no dropped/lost information. This feature may be used in place of the zone feature for security applications.

Zone Compliance or Landmark Detection

The feature of Zone Compliance is the capability to store a set of coordinates inside the Prism

TM2 that make up an area called a zone. The Prism TM2 can then perform certain actions upon detecting where the vehicle is in relation to the zone. This function acts similar to Exception

Conditions in the Fleet Director software depending on how it is programmed. Upon entering or leaving a zone, the Prism TM2 can send a message or change its operating condition. To most people it is obvious what zone compliance means due to the Fleet Director’s current standards, but with the Prism TM2 having the internal zone capabilities, a whole new level of zone compliance is capable.

A few examples of this new capability would be that by setting up a zone around a customer’s yard, the truck driver is no longer required to press an “In Yard” or “Left Yard” button. When set up around a customer site, the driver would no longer be required to send a message if he was at a site too long, nor would Fleet Director have to time the “At Site” condition or locate the vehicle to insure it is still there. And, when combined with the In Motion Detection feature, the customer would not have to locate his truck all night long to make sure it has not left the yard due to theft.

In addition, since the GPS Receiver is locating itself continually, the Prism TM2 would send a message with the exact time of the event happening. This would eliminate the 15-minute error factor in Fleet Director. There are a maximum of three (3) zones that can be configured into each unit.

A zone can either be a circle with a center and radius or a square with a center and distance to the edge. In order to determine a zone, you will need to find the Latitude and Longitude for the center of the zone. Next, determine the distance, in meters, from the center of the zone to its edge.

Next, you will need to determine the Hysteresis. This is a gray area outside and inside the edges of the zone that will account for jitter in the locations. You will be able to select the size of the

Hysteresis from 0 meters to 250 meters. Within the Hysteresis, you will not be considered inside or outside the zone. The vehicle will effectively be in “No Mans Land”. The Hysteresis can also be turned off so that the actual edges of the zone are used for the exception.

Teletrac, Inc. - Prism TM2 Information and Installation Guide

Speed Threshold

A natural spin-off from time and distance is speed. The Prism TM2 can detect its own speed more accurately then Fleet Director (+/- 1 mph accuracy). Because of this, the Prism TM2 can detect speed violations thus alerting dispatch of possible violations or exception condition.

Thresholds can be set in the Prism TM2 to trigger warning messages when the vehicle goes above a specific speed. Even more, a timer can be set to alert dispatch only if the threshold is detected for a required length of time. In order for the messages to be sent, the speed must pass through the set speed.

Note: The actual speed must pass through the set speed in order to trigger the message.

Dynamic Power Management

By default, the Prism TM2 is programmed with a robust interactive power management routine.

This routine forces the Prism TM2 to periodically shut down its internal high current components

(the GPRS modem and the GPS receiver) while the vehicle ignition is OFF. This feature will decrease the Prism TM2 current consumption significantly. While these components are shut down, the workstation is incapable of setting up a communications link with the Prism TM2 for the requesting of location or the sending of messages. While the Prism TM2 is asleep the ability to send messages from the MDT and do vehicle status changes (in motions, input change, etc.) will not be prevented but may suffer a slight delay caused by the Prism TM2 waking up.

To the customer (and the system) it appears as though the Prism TM2 is out of the coverage area while the Prism TM2 is asleep. To reduce the possible confusion as to if the unit is asleep or out of coverage, when the unit goes to sleep it will send a message prior to shutting down to indicate the shut down and to inform how long the unit will be asleep. Otherwise, if no message is captured then the unit is out of the coverage area.

When the unit does go to sleep, it will check it’s operating conditions to see if it is allowed to go to

Note: Unit must have sleep then, it will start a timer, if the conditions remain the same at the end of the timer then the unit will go to sleep. The unit will the following conditions in order to go to sleep: send a message to the workstations saying that in X minutes it will be going to sleep for Y hours (this message must be set up

Ignition Off

Not moving in Fleet Director as a message for now). Once the Prism TM2 has gone to sleep it is unreachable until the operating conditions change or it is time to wake up. If the unit wakes up and determines that the operating conditions have not changed it will send out the same message as above.

In order to keep a unit awake, the operating conditions must change. For instance, since the

Prism TM2 is connected to sense ignition on/off, when the ignition is turned on the unit will wake up. Another way to keep the unit awake is to keep it busy. By moving the unit into a status that locates it more frequently than the time required for it to go to sleep, it will remain awake since the timer is reset after each activity with the unit.

When a unit is out of the coverage area or asleep, it will send messages to the buffer. Once the messages are in the buffer they are stored until they are downloaded. The unit will still go to sleep with messages in the buffer. Events or reports that occur while the unit is asleep will still be stored in the buffer.

When programming the Prism TM2 , you will have the option to fill in the amount of time the unit will wait once it has determined that it can go to sleep, how long it will remain asleep and how long it will stay awake when it does wake up.

Teletrac, Inc. - Prism TM2 Information and Installation Guide

Message Store and Forward (Message History)

The unit has ability to store locations, event history and messages. Any of these pieces of data can be stored while the Prism TM2 migrates outside the GPRS coverage area. The unit will first attempt to send the message or event, if it fails, the message will be sent to a memory buffer for later delivery. When a report is run, the coverage area will appear greater. With the addition of storing message, this feature will allow the driver to continue to send status messages while outside the GPRS coverage area to time stamp his activities so a compliance report can be generated when he returns to the GPRS coverage area. Also, the messages will be stored even if the unit goes to sleep.

ISM TM2 I NSTALLATION I NSTRUCTIONS

This unit covers the installation of the PRISM TM2 . We will take a look at the equipment and walk through a typical installation. As a note, this section does not cover the programming of the

PRISM TM2 .

NOTE: This section discusses a typical installation in a step-by-step fashion. Please e-mail the

Field Service group for questions concerning special installations.

PRE-INSTALLATION CONSIDERATIONS a) Perform a Pre-installation Vehicle Checkout. Ensure that major electrical/mechanical components are in working order in the event anything happens to the vehicle at a later date.

Check the headlamps, air conditioner, dome lights, turn signals, radio, windshield wipers and, if at all possible, start the vehicle engine. b) Prior to beginning the PRISM TM2 installation, record the unit’s IP address and vehicle ID on the installation form. The stickers, created at the time of provisioning, need to be affixed to the installation forms. A set of these forms is to be left with the customer and a set placed in their file. This reduces the need to uninstall the unit then reinstall it in order to find the unit’s number. The units will have their MIN activated upon provisioning in the metro. Upon MIN activation Teletrac starts paying for it’s use and therefore, units should be installed as quickly as possible and not kept in stock. c) Next, remove the courtesy light fuse in order to avoid running the vehicles battery down during installation. d) Before beginning any work you will need to find suitable locations for the following equipment.

As a courtesy, all equipment will be installed in a manner that will conceal its location, usually behind the dashboard. You will need a flat surface for mounting. Also, keep in mind that coax for the antennas must be run behind panels and in pillars. Review the equipment location with the customer and obtain their approval.

MDT

12 VDC and ground spots e) While you are determining the mounting location use the system layout as a reference to plan the wiring harness routing and connection points. Typical locations are under or behind the vehicle dashboard. Avoid places with extreme vibration, heat or moisture. f) Once the hardware is mounted and when you are making the wiring connections, hold the

PRISM TM2 in place and route the unit’s wiring harness to the connection point at the target wire. Cut the wires to the correct length and make the connections. Once the first installation is complete you can prepare the rest of the equipment (harnesses) in advance of the actual installation.

NOTE : Due to the importance of the connections, it is mandatory that all connections be either

Soldered or Crimped with the proper crimping tool . Wrap and tape, Scotch-Loc., or T-Tap connections MAY NOT BE USED when installing this system.

GPS Antenna

Now that there are two antennas and one is a GPS antenna, placement becomes critical. The received signal levels for the GPS antenna from the satellites are very low in power

(approximately -136 dBm) so that any blockage of the antenna can affect the quality of the location computed by the receiver . The following figures show examples of good and poor vehicle

GPS antenna mounting locations.

When installing the GPS antenna on a vehicle roof, make sure there are no obstructions close to the antenna that might block the view 360

to the horizon. Nothing should block the antenna 5

° above the horizon - for example, air horns or marker lights. The best location is usually near the center of the roof, although it is also desirable to locate the cellular antenna as far from the GPS antenna as is practical. It is best to keep the antenna at least 12” from any other antenna. IF using the hidden combo antenna, it should be placed on the highest part of the dash or inside the headliner, see the note below. Be sure to use the correct antenna for this application.

Also, kinks or tight knots in the antenna cable can cause problems that will not allow the PRISM

TM2 to operate. When laying out the antenna cable, care should be taken so that the cable will not be subjected to crushing or strain.

No Blockage above 5

Examples of good and poor GPS antenna placement

NOTE : To insure that Hidden Combo – ARC antenna will function properly, mount the antenna’s base (large flat side) against a metal surface.

NEVER shorten or lengthen the antenna co-ax cable.

NEVER locate the antenna near the transceiver unit, or other black box device.

NEVER mount the antenna vertically.

NEVER mount the antenna below the “beltline” of the vehicle.

NEVER mount the antenna in the trunk or engine comparTM2ent.

NEVER use silver (metallic) duct tape to secure the antenna

GPS performance will be less than optimum when using a hidden antenna. When using this type of antenna, be aware of surrounding obstructions that could further reduce GPS operation.

GPRS Antenna

The cellular anten na used by the PRISM TM2 for GPRS service is a standard black 3dB gain whip. It mounts with a standard NMO

"Motorola" mount and requires ground plane to work properly. If possible, the GPRS antenna should be locate at least 12” from any other antenna. Ensure that the cable does not get crushed during installation.

5. Using a volTM2eter, make sure that the ignition line (white harness wire pin 6) is correctly wired to the keyed side of the ignition switch at the ACCESSORY wire. This wire goes high upon turning the key but it goes low when at the CRANK position. Also that the power input

(red wire) is connected to a constant (unswitched) +12v DC supply.

6. Verify that the existing harness has all required wires soldered or crimped for reliability.

7. Attach the VLU plus

wiring harness 37-pin connector to the adapter, tighten the screws, and then plug the adapter into the PRISM TM2 unit. the to the chassis of the vehicle utilizing the mounting tabs. Secure the unit with four (4) self-tapping machine screws.

9. A new antenna must be installed since the connectors from the Connect the SMA connector to the GPRS antenna port on the unit. Connect the SMB GPS connector to the PRISM TM2 .

10. Reattach the main vehicle power and/or replace the fuse.

PRISM TM2 New Installations

1. Find suitable locations for the PRISM TM2 , and GPS/GPRS combo antenna. Select a

PRISM TM2 mounting location that is free of moisture or heat, typically behind the dashboard or under the seat.

2. Install the GPS antenna and route the cable to the PRISM TM2 location. Typically, the installation will require a hole drilled into the vehicle. The exact size of the hole is dependant upon the antenna mount used. Keep in mind that coax must be run behind panels. Note that the GPS antenna should have no blockage 5

above the horizon. (See Antenna Placement page 5.)

3. Install the GPRS antenna and route the antenna cable to the PRISM TM2 location. This will also typically require a hole drilled into the vehicle. The exact size of the hole is dependant upon the antenna mount used. Keep in mind that coax must be run behind panels. (See

Antenna Placement page 5.) If a Combo antenna is being used only one hole will be required.

4. Apply silicone around both antenna bases if holes are required.

Global Positioning Systems - A Primer

Navigation and positioning are crucial to so many activities and over the years all kinds of technologies have tried to simplify the task including Teletrac's RF system. The U.S.

DeparTM2ent of Defense (DoD) decided the U.S. military needed a super-precise form of worldwide positioning. And fortunately, they had the kind of money ($12 billion) it took to build it.

The result is the Global Positioning System. The Global Positioning System (GPS) is a worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations.

GPS uses these "man-made stars" as reference points to calculate positions accurate to within meters. In fact, with advanced forms of GPS you can make measurements to better than a centimeter. In a sense, it's like giving every square meter on the planet a unique address.

GPS receivers have been miniaturized to just a few integrated circuits and so are becoming very economical. And that makes the technology increasingly accessible. The U.S. military was able to successfully deploy GPS for the first time during the Gulf War in 1991. It is credited as being one of the factors that led to the fast victory over Iraqi forces as our military units were "visible" (that is, their locations and movements were precisely known) to strategists at all times.

Here's how GPS works in five logical steps:

Here is a summary of each of the steps involved with GPS in order to determine a location. This is the first part of Teletrac finding the locations of vehicles using a Prism TM2 . Once a location is determined, then it is sent via another system. We'll explain each of the following points in the next five sections.

1. The basis of GPS is "triangulation" from satellites.

2. To "triangulate," a GPS receiver measures distance using the travel time of radio signals.

3. To measure travel time, GPS needs very accurate timing, which it achieves with some tricks.

4. Along with distance, you need to know exactly where the satellites are in space. High orbits and careful monitoring are the secret.

5. Finally you must correct for any delays the signal experiences as it travels through the aTM2osphere.

1622-0300 B2-5 05 2006 10

Teletrac, Inc. - Prism TM2 Information and Installation Guide

Step 1: Triangulating from Satellites

Improbable as it may seem, the whole idea behind GPS is to use satellites in space as reference points for locations here on earth. That's right, by very, very accurately measuring our distance from three satellites we can "triangulate" our position anywhere on earth. Forget for a moment how our receiver measures this distance. We'll get to that later. First consider how distance measurements from three satellites can pinpoint you in space.

DEA

EOMETRICALLY

Suppose we measure our distance from a satellite and find it to be 11,000 miles.

Knowing that we're 11,000 miles from a particular satellite narrows down all the possible locations we could be in the whole universe to the surface of a sphere that is centered on this satellite and has a radius of 11,000 miles.

Next, say we measure our distance to a second satellite and find out that it's 12,000 miles away.

That tells us that we're not only on the first sphere but we're also on a sphere that's 12,000 miles from the second satellite. Or in other words, we're somewhere on the circle where these two spheres intersect.

If we then make a measurement from a third satellite and find that we're 13,000 miles from that one, that narrows our position down even farther, to the two points where the 13,000 mile sphere cuts through the circle that's the intersection of the first two spheres.

1622-0300 B2-5 05 2006 11

Teletrac, Inc. - Prism TM2 Information and Installation Guide

So by ranging from three satellites we can narrow our position to just two points in space.

To decide which one is our true location we could make a fourth measurement. But usually one of the two points is a ridiculous answer (either too far from Earth or an impossible velocity) and can be rejected without a measurement.

A fourth measurement does come in very handy for another reason however, but we'll tell you about that later.

Next we'll see how the system measures distances to satellites.

Step 2: Measuring Distance from a Satellite

We saw in the last section that a position is calculated from distance measurements to at least three sa tellites. But how can you measure the distance to something that's floating around in space? We do it by timing how long it takes for a signal sent from the satellite to arrive at our receiver.

DEA

ATHEMATICALLY

In a s en se the w ho le thing boils down to those "velocity times travel time" math problems we did in high school. Remember the old: "If a car goes 60 miles per hour for two hours, how far does it travel.?"

Velocity (60 mph) x Time (2 hours) = Distance (120 miles)

In the cas e of GPS we're measuring a radio signal so the velocity is going to be the speed of light or roughly 186,000 miles per second. The problem is me asuring the travel time.

S YNCHRONIZING OUR W ATCHES

The timing problem is tricky. First, the times are going to be awfully short. If a satellite were right overhead, the travel time would be something like 0.06 seconds. So we're going to need some really precise clocks. We'll talk about those soon.

1622-0300 B2-5 05 2006 12

Teletrac, Inc. - Prism TM2 Information and Installation Guide

But assuming we have precise clocks, how do we measure travel time? To explain it let's use a goofy analogy:

Suppose th ere was a way to get both the satellite and the receiver to start playing "The Star-

Spangled Banner" at precisely 12 Noon. If sound could reach us from space (which, of course, is ridiculous ) then standing at the receiver we'd hear two versions of "The Star-Spangled Banner," one from o ur receiver and one from the satellite.

These two versions would be out of sync. The version coming from the satellite would be a little delayed because it had to travel over 11,000 miles.

If we wanted to see just how delayed the satellite's version was, we could start delaying the receiver's version until they fell into perfect sync.

The amount we have to shift back the receiver's version is equal to the travel time of the satellite's version. So we just multiply that time times the speed of light and BINGO! we've got our distance to the satellite.

That's basically how GPS works.

Only instead of "The Star-Spangled Banner" the satellites and receivers use something called a

"Pseudo Random Code." - which is probably easier to sing than "The Star-Spangled Banner."

A R ANDOM C ODE ?

The Pseudo Random Code (PRC) is a fundamental part of GPS. Physically it's just a very complicated digital code, or in other words, a complicated sequence of "on" and "off" pulses as shown here:

The signal is so comp licated that it almost looks like random electrical noise. Hence the name

"Pseudo-Random."

There are several good reasons for that complexity: First, the complex pattern helps make sure that the receiver doesn't accidentally sync up to some other signal. The patterns are so complex that it's highly unlikely that a stray signal will have exactly the same shape.

Since each satellite ha s its own unique Pseudo-Ran dom Code this complexity also guarantees that the receiver won 't accidentally pick up another satellite's si gnal. So all the satellites can use the same frequency without jamming each other. And it makes it more difficult for a hostile force to jam the system. In fact the Pseudo Random Code gives the DoD a way to control access to the system.

But there's another reason for the complexity of the Pseudo Random Code, a reason that's crucial to making GPS economical.

The codes make it possible to use "information theory" to "amplify" the GPS signal. And that's why GPS receivers don't need big satellite dishes to receive the GPS signals.

We glossed over one point in our goofy Star-Spangled Banner analogy. It assumes that we can guarantee that both the satellite and the receiver start generating their codes at exactly the same time. But how do we make sure everybody is perfectly synced? Stay tuned and see.

1622-0300 B2-5 05 2006 13

Teletrac, Inc. - Prism TM2 Information and Installation Guide

Step 3: Getting Perfect Timing

If meas uring the travel time of a radio signal is the key to GPS, then our stop watches had better be darn good, becau se if their timing is off by just a thousandth of a second, at the speed of light, that translates into almo st 200 miles of error!

On the satelli te side, timing is almost perfect because they have incredibly precise atomic clocks on board.

But what about our re ceivers here on the ground?

Remember that both the satellite and the receiver need to be able to precisely synchronize their pseudo-random codes to make the system work.

If our receivers needed atomic clocks (which cost upwards of $50K to $100K) GPS would be a lame duck technology. Nobody could afford it.

Luckily the designers of GPS came up with a brilliant little trick that lets us get by with much less accurate cl ocks in our receivers. This trick is one of the key elements of GPS and, as an added side benefit, it means that every GPS receiver is ess entially an atomic-accuracy clock.

The secret to perfect timing is to make an extra satellite measurement.

That's right, if three perfect measurements can lo cate a point in 3-dimensional space, then four imperfect measurements can do the same thing.

XTRA

EASUREMENT

URES

IMING

FFSET

If everything were perfect (i.e. if our receiver's clocks were perfect) then all of our satellite ranges would intersect at a single point (which is our position). But with imperfect clocks, a fourth measurement, done as a cross-check, will NOT intersect with the first thr ee.

So the receiver's computer says "Uh-oh! There is a discrepancy in my measurements. I must not be perfectly synced with universal time."

Si nce any offset from univ ersal time will affect all of our measurements, the receiver looks for a single correction factor that it can subtract from all it s timing measurements that would cause them all to intersect at a single point.

That correction brings the receiver's clock back into sync with universal time, and bingo! - you've got atomic accuracy time right in the palm of your hand.

Once it has that correction it applies to all the rest of its measurements and now we've got precise positioning.

One consequence of this principle is that any decent GPS receiver will need to have at least four channels so that it can make the four measurements simultaneously.

O.K, with the pseudo-random code as a rock solid timing sync pulse, and this extra measurement trick to get us perfectly synced to universal time, we have got everything we need to measure our distance to a satellite in space.

But for the triangulation to work we not only need to know distance, we also need to know exactly where the satellites a re.

Step 4: Knowing Where a Satellite is in Space

In this tutorial we've been assuming that we know where the GPS satellites are so we can use them as reference point s.

But how do we know exactly where they are? After all they're floating around 11,000 miles up in space.

A H IGH S ATELLIT E G ATHERS N O M OSS

That 1 1,000 mile altitude is actually a benefit in this case, because something that high is well clear of the aTM2osphere. And that will mean it will orbit according to very simple mathematics.

The Air Force has injected each GPS satellite into a very precise orbit, according to the GPS master plan.

On the g round all GPS receivers have an almanac programmed into their computers that tells th em where in the sky each satellite is, moment by moment.

ONSTANT

ONITORING

DDS

RECISION

The basic orbits are quite exact but just to make things perfect the GPS satellites are constantly monitored by the DeparTM2ent of Defense.

They use very precise radar to ch eck each satellite' s exact altitude, position and speed.

The errors they're checking for a re called "ephemeris erro rs" because they affect the satellite's orbit or "ephemeris." These erro rs are caused by gravitational pu lls from the moon and sun and by the pressure of solar radiation on the satellites.

The errors are usua lly very slight but if you want great accura cy they must be taken into account.

1622-0300 B2-5 05 2006 15

Teletrac, Inc. - Prism TM2 Information and Installation Guide

G ETTING THE M ESSAGE O UT

Once the DoD has measured a satellite's exact position, they relay that information back up to the satellite itself. The satellite then includes this new corrected position information in the timing signals it's broadcasting.

So a GPS signal is more than just pseudo-random code for timing purposes. It also contains a navigation message with ephemeris information as well.

With perfect timing and the satellite's exact position you'd think we'd be ready to make perfect position calculations. But there's trouble afoot. Check out the next section to see what's up.

Step 5: Correcting Errors

Up to now we've been treating the calculations that go into GPS very abstractly, as if the whole thing were happening in a vacuum. But in the real world there are lots of things that can happen to a GPS signal that will make its life less than mathematically perfect.

To get the most out of the system, a good GPS receiver needs to take a wide variety of possible errors into account. Here's what they've got to deal with.

OUGH

RIP THROUGH THE

ATM2

OSPHERE

First, one of the basic assumptions we've been using throughout this tutorial is not exactly true.

We've been saying that you calculate distance to a satellite by multiplying a signal's travel time by the speed of light. But the speed of light is only constant in a vacuum.

As a GPS signal passes through the charged particles of the ionosphere and then through the water vapor in the troposphere it gets slowed down a bit, and this creates the same kind of error as bad clocks.

1622-0300 B2-5 05 2006 16

Teletrac, Inc. - Prism TM2 Information and Installation Guide

There are a couple of ways to minimize this kind of error. For one thing we can predict what a typical delay might be on a typical day. This is called mod eling and it helps but, of course, aTM2ospheric conditions are rarely exactly typical.

Another way to get a handle on these aTM2osphere-induced errors is to compare the relative speeds of two different signals. This "dual frequency" measurement is very sophisticated and is only possible with advance d receivers.

OUGH

RIP ON THE

ROUN D

Trouble for the GPS signal doe sn't end when it gets down to th e ground. The signal may bounce off various local obstructio ns before it gets to our receiver.

T his is called multipath error and is similar to the ghosting you might see on a TV. Good receive rs use sophisticated signal rejection techniques to minimize this problem.

ROBLEMS AT THE

ATELLITE

Even though the satellite s are very sophisticated they do account for some tiny errors in the system.

The atomic clocks they use are very, very precise but they're not perfect. Minute discrepancies can occur, and these translate into travel time measurement errors.

And eve n though the satellites position s are constantly monitored, they can't be watched every second. So slight position or "ephemeris" errors can sneak in between monitoring times.

OME

NGLES ARE

ETTER

HAN

THERS

Basic geometry itself can magnify these other errors with a principle called "Geometric Dilution of

Precision" or GDOP. It sounds complicated but the principle is q uite simple.

Th u picks a few and ignores the rest. availa ble than a receiver needs to fix a position, so the receiver

If it picks satellites that are close together in the sky the intersecting circles that define a position will cross at very shallow angles. That increases the gray area or error margin around a position.

1622-0300 B2-5 05 2006 17

Teletrac, Inc. - Prism TM2 Information and Installation Guide

If it picks satellites that are widely separated the circles intersect at almost right angles and that minimizes the error region.

Good receivers determine whic h satellites will give the lowe st GDOP.

NTENTIONAL

RRORS

As hard as it may be to be lieve, the same government that spe nt $12 billion to develop the most accurate navigation system in the world is intentionally degradi ng its accuracy. The policy is called "Selective Availability" or " SA" and the idea behind it i s to make sure that no hostile force or terrorist group can use GPS to make accurate weapons.

B asically the DoD introduces some "noise" into the satellite's clock data which, in turn, adds noise

(or inaccuracy) into position calculations. The DoD may also be sending slightly erroneous orbital data to the satellites which they transmit back to receivers on the ground as part of a status messag e.

Together these factors make SA th e biggest single source of inaccuracy in the system. Military receivers use a decryption key to re move the SA errors and so they're much more accurate.

The Bottom Line

Fortunately all of these inaccuracies still don't add up to much of an e rror. And a form of GPS called "Differential GPS" can significantly reduce these problems.

Message Code Usage

General

NOTE : The term VLU means all Teletrac location units.

The purpose of this paper is to give guidelines on how to standardize message code usage for Fleet Director, MDTs and VLUs. The standardization of message codes is intended to help make it easier to develop and support customer applications. The following bullet list expresses the basic reasons for message code standardization.

•

Training – Standardization of codes make the code usage intuitive by using the same codes for similar messages. This helps both the newcomer and the trainer since code usage has common rules that easily understood.

•

Customer Support – As in training the code standards make it easier to support the customer when all customers are setup with common rules on code usage. This avoids the confusion associated with have multiple customer applications using similar messages but uncommon codes.

•

Installation Support – By standardizing code usage standard workstation,

MDT and VLU configurations can be developed as packages with minimal customization requirements. This prevents mistakes in application setup and decreases the cost and time to install customer equipment.

•

Code Conservation – Message codes are limited, especially for inbound messages. All messages cannot be given unique. By standardizing codes, commonly used messages can be given unique codes leaving the remaining codes for reuse in new applications.

•

Script Development – By developing standardized relationships for codes and script features and VLU hardware, script development is made less costly.

Without standardization far more scripts would need to be developed for different uses of the codes for similar functions or features. This would be very confusing since most scripts would have minor differences and keeping track of the difference would be difficult. Ultimately the support personnel would standardize on script usage by using the script most familiar to them thus achieving a similar affect as code standardization. Unfortunately different installers would have different standards and engineering would still have to produce large numbers of scripts to meet everyone’s expectations.

•

System Development – As new system capabilities are developed along with new workstation software and mobile equipment, the usage of message codes play a part on service privileges and expectations. By standardizing codes, the system can more easily be developed to handle ranges of codes or a selected

1622-0300 B2-5 05 2006 4

Teletrac, Inc. - Prism TM2 Information and Installation Guide few codes with similar function or features rather than being expected to handle all codes with different with a variety of possible functions or features.

Code standardization should take into consideration both inbound and outbound message usage. It should also consider the limitations within the System, the VLU, the MDT, and the workstation software that force some messages to be reserved or identified for special usage. For example, the MDT has built in limitations due to resource limitations and the

VLU has unchangeable firmware where codes force VLU behavior differences.

There are three forms of inbound messages: ACM which are also known as ECM or canned inbound messages, RCM_A which are known as Form Fill message and LIM which are variable length free form message, which can be either Form Fill or Free Text.

This paper focuses on only canned inbound messages. The Teletrac Air Interface protocol restricts inbound canned messages to ACM 11-99 codes. There are other message codes available for special services and emergency messages but have system restrictions due to EMS (Episode Management System) services (i.e. ACM 235-Panic,

ACM 207-Stolen, ACM 167-Roadside Assistance, etc).

There are two types of outbound message that are called FCM and Long FCM. The FCM codes are allocated by the Teletrac Air Interface Protocol and are not the subject of this paper. However, this paper does address the usage of codes within the use of FCM 220,

221 and 222. To date all outbound canned messages sent to the MDT use the FCM 220 message and send one of 256 possible codes (0-255) within the message structure as a canned message code.

Inbound Message Guidelines

As mentioned above the ACM 11-99 codes can be used for inbound canned messages.

From those available 89 message codes the following considerations must be made:

•

The MDT supports 40 canned inbound messages.

The MDT supports 10 emergency messages.

The VLU has 4 inputs capable of 8 messages (each ON and OFF).

The VLUplus & PRISM TM2 has zones requiring 2 messages each (zone entry and exit).

•

The VLUplus & PRISM TM2 will have common script functions like Power

Management and Tow-Away which require message codes.

•

The VLUplus & PRISM TM2 uses code “0” for Store and Forwarded locations.

•

The current system has allocated messages ACM 90-99 as alternate notification messages.

•

The RF VLU has special functionality for ACM 94, 97 and 99.

Although the system currently may not take advantage of these features or in the future may change the definition, the standardization of codes should expect that the codes are used as intended. The following table shows how the inbound message codes could be allocated.

Outbound Message Guidelines

As mentioned above the inbound canned message codes can be 0-255 and are sent as part of the FCM 220 message structure. From these available 256 message codes the following considerations must be made:

•

The MDT can support up to 40 canned outbound messages.

The MDT allows codes 1-6 to control its outputs.

The Prism TM2 can use any of the 256 codes for script controls and commands.

•

The Prism TM2 passes all 256 message codes to the MDT thus causing the

MDT to display text if the message is understood by the MDT.

•

The RF VLU allows message codes 80-143 to control its output, however only 20 of the codes are utilized (80-84, 96-100, 112-116 and 128-132).

Final Comments

The key to good standardization is to keep similar message grouped together and to make the code usage intuitive. Unfortunately sometimes intuitive and grouping don’t mix. The best standardization method would never use the same message code twice however we don’t have that luxury due to limited code availability (especially on the inbound messages). For Teletrac the best approach is to review our message code usage and anticipate future needs. As we already know, some messages definitions are similar and used by all customers (or nearly all-Ignition On/Off, VLU Sleep, etc.). These commonly used messages should become standardized.

We also know that some messages are used for status, some for information and others for control. We should try to group these three groups as best we can. Unfortunately, some messages can’t fit neatly into standard grouping definitions due to either multiple uses in the same installation (i.e. Panic might be in the MDT emergency menu and also in the VLU for a hidden switch). When dealing with these conflicts its best to think of installation support and script standardization. We don’t want to make it difficult on support personnel when similar functions end up being different for each case.

Furthermore, if we keep changing which message is used for standard script functions

(input activity) we will end up with a lot of scripts with minor differences that will be hard to track. For the above Panic message example it would be best to use the Input 2 message code ACM 53 for Panic in both the MDT and VLU so that the basic multi-input script could work without changes and the installer knows that input two always causes an ACM 53 message.

Simple Guidelines

Please follow these guidelines when configuring or using the Prism TM2. Violating these guidelines may be dangerous, illegal or otherwise detrimental. Further detailed information is provided in this manual.

Do Not Operate Where Prohibited

Do not allow the Prism TM2 to operate wherever wireless phone use is prohibited or when doing so may cause interference or danger. Examples include but are not limited to operation in hospitals, aircraft, near blasting sites or wherever operation can cause interference.

Interference

Like all wireless devices, the Prism TM2 may encounter electrical interference that may affect its performance.

Avoid Body Contact with Device During Operation

Do not operate the Prism TM2 in direct contact with your body. Maintain minimum separation distance of 6.2 inch (20 cm) between the device antenna and any parts of your body. Antenna must be installed on the top of the vehicle or the windshield area of the vehicle, in order to maintain a distance of 20 cm from a human body.

Qualified Service

Except for batteries and Subscriber Identification Module (SIM) card, the Prism TM2 contains no user serviceable or replaceable parts. Non-functioning units must be returned to an authorized service center for repair or replacement.

Water-Resistance

Detailed Safety Information

Exposure to Radio Frequency Signals

The Prism TM2 is a low power radio transmitter and receiver. When it is ON, it receives and also sends out radio frequency (RF) signals.

In August 1996, the Federal Communications Commissions (FCC) adopted RF exposure guidelines with safety levels for hand-held wireless phones. Those guidelines are consistent with safety standards previously set by both U.S. and international standards bodies:

•

ANSI C95.1 (1992)

•

NCRP Report 86 (1986)

•

ICNIRP (1996)

Those standards were based on comprehensive and periodic evaluations of the relevant scientific literature. For example, over 120 scientists, engineers, and physicians from universities, government health agencies, and industry reviewed the available body of research to develop the ANSI Standard (C95.1)

While the Prism TM2 is not intended for hand-held use, its design nonetheless complies with the FCC guidelines (and those standards).

Electronic Devices

Most modern electronic equipment is shielded from RF signals. However, certain electronic equipment may not be shielded against the RF signals generated by the Prism

TM2.

Pacemakers

The Health Industry Manufacturers Association recommends that a minimum separation of six (6”) inches be maintained between a handheld wireless phone and a pacemaker to avoid potential interference with the pacemaker. These recommendations are consistent with the independent research by and recommendations of Wireless Technology

Research.

Persons with pacemakers:

•

Should ALWAYS keep the Prism TM2 more than eight inches from their pacemaker with the device is operational.

•

Should not carry the Prism TM2 on their person

•

If there is any reason to suspect that interference is taking place, the

Prism TM2 battery pack should be removed immediately.

Other Medical Devices

If any other personal medical devices are used in the vicinity of a Prism TM2, consult the manufacturers of the medical devices to determine if they are adequately shielded from external RF energy. Physicians may be able to assist in obtaining this information.

Disable operation of the Prism TM2 by removing the battery pack in health care facilities when any regulations posted in these areas prohibit the use of wireless phones or twoway radios. Hospitals and health care facilities may be using equipment that could be sensitive to external RF energy.

Teletrac, Inc. - Prism TM2 Information and Installation Guide

Vehicles

RF signals may affect improperly installed or inadequately shielded electronic systems in motor vehicles. Check with the manufacturer or its representative regarding the vehicle.

Also consult the manufacturer of any equipment that has been added to the vehicle.

Posted Facilities

Disable operation of the Prism TM2 by removing the battery pack in any facility where posted notices prohibit the use of wireless phones or two-way radios.

Aircraft

FCC regulations prohibit using wireless phones while in the air. Disable operation of the

Prism TM2 by removing the battery pack prior to boarding or loading in an aircraft

Blasting Areas

To avoid interfering with blasting operations, disable operation of the Prism TM2 by removing the battery pack when in a “blasting area” or in areas posted: “Turn off two-way radio”. Obey all signs and instructions.

Potentially Explosive ATM2ospheres

Disable operation of the Prism TM2 by removing the battery pack prior to entering any area with a potentially explosive aTM2osphere and obey all signs and instructions.

Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death.

Areas with a potentially explosive aTM2osphere are often, but not always marked clearly.

Potential areas may include: fueling areas (such as gasoline stations); below deck on boats; fuel or chemical transfer or storage facilities; vehicles using liquefied petroleum gas (such as propane or butane); areas where the air contains chemicals or particles

(such as grain, dust, or metal powders); and any other area where it would normally be advisable to turn off motor vehicle engines.

For Vehicles Equipped with an Air Bag

An air bag inflates with great force. DO NOT place objects, including the Prism TM2, in the area over the air bag or in the air bag deployment area. If in-vehicle wireless equipment is improperly installed and the air bag inflates, serious injury could result.
