Safety Information Before you use your Trimble® SPS GPS receiver, make sure that you have read and understood all safety requirements. Regulations and
safety The receivers contain an internal radio-modem and can send signals through Bluetooth® wireless technology or through an external data
communications radio. Regulations regarding the use of the 450 MHz radio-modems vary greatly from country to country. In some countries, the unit can be
used without obtaining an end-user license. Other countries require end-user licensing. For licensing information, consult your local Trimble dealer.
Bluetooth and 900 MHz radio-modems operate in license-free bands. Before operating an SPS882 Smart GPS antenna, determine if authorization or a license
to operate the unit is required in your country. It is the responsibility of the end user to obtain an operator's permit or license for the receiver for the location
or country of use. For FCC regulations, see Notices, page 2.
Type approval Type approval, or acceptance, covers technical parameters of the equipment related to emissions that can cause interference. Type approval is
granted to the manufacturer of the transmission equipment, independent from the operation or licensing of the units. Some countries have unique technical
requirements for operation in particular radio-modem frequency bands. To comply with those requirements, Trimble may have modified your equipment to be
granted Type approval. Unauthorized modification of the units voids the Type approval, the warranty, and the operational license of the equipment.
Exposure to radio frequency radiation For 450 MHz radio Safety. Exposure to RF energy is an important safety consideration. The FCC has adopted a safety
standard for human exposure to radio frequency electromagnetic energy emitted by FCC regulated equipment as a result of its actions in General Docket
79-144 on March 13, 1986. Proper use of this radio modem results in exposure below government limits. The following precautions are recommended: · DO
NOT operate the transmitter when someone is within 20 cm (7.
8 inches) of the antenna. DO NOT operate the transmitter unless all RF connectors are secure and any open connectors are properly terminated. · SPS882
Smart GPS Antenna User Guide 3 Safety Information · DO NOT operate the equipment near electrical blasting caps or in an explosive atmosphere. All
equipment must be properly grounded according to Trimble installation instructions for safe operation. All equipment should be serviced only by a qualified
technician. · · For license-free 900 MHz radio1 C CAUTION For your own safety, and in terms of the RF exposure requirements of the FCC, always observe
the precautions listed here. · DO NOT operate the transmitter when someone is within 20 cm (7.8 inches) of the antenna. The minimum operating distance
between an SPS882 with an internal 900 Mhz radio transmitter and a SPS882 900 Mhz rover is 0.6 m (2 ft).
Do not co-locate the antenna with any other transmitting device. · · For Bluetooth radio The radiated output power of the internal Bluetooth wireless radio is
far below the FCC radio frequency exposure limits.

Nevertheless, the wireless radio shall be used in such a manner that the Trimble receiver is 20 cm or further from the human body. The internal wireless
radio operates within guidelines found in radio frequency safety standards and recommendations, which reflect the consensus of the scientific community.
Trimble therefore believes that the internal wireless radio is safe for use by consumers. The level of energy emitted is far less than the electromagnetic energy
emitted by wireless devices such as mobile phones. However, the use of wireless radios may be restricted in some situations or environments, such as on
aircraft. If you are unsure of restrictions, you are encouraged to ask for authorization before turning on the wireless radio. Installing antennas C CAUTION
For your own safety, and in terms of the RF exposure requirements of the FCC, always observe these precautions: Always maintain a minimum separation
distance of 20 cm (7.8 inches) between yourself and the radiating antenna.
Do not co-locate the antenna with any other transmitting device. C CAUTION The GPS antenna and its cabling should be installed in accordance with all
national and local electrical codes, regulations, and practices. The antenna and cabling should be installed where they will not become energized as a result
of falling nearby power lines, nor be mounted where they are subjected to overvoltage transients, particularly lightning. Such installations require additional
protective means that are detailed in national and local electrical codes. 1.
900 MHz radios are not used in Europe. 4 SPS882 Smart GPS Antenna User Guide Safety Information This device has been designed to operate with the
antennas listed below. Antennas not included in this list are strictly prohibited for use with this device. The required antenna impedance is 50 ohms. The
antennas that can be used (country dependent) with the 450 MHz radio are 0 dBi and 5 dBi whip antennas.
The antennas that can be used (country dependent) with the 900 MHz radio are 0 dBi, 3 dBi, and 5 dBi whip antennas. To reduce potential radio interference
to other users, the antenna type and its gain should be so chosen so that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted
for successful communication. Battery safety C WARNING Do not damage the rechargeable Lithium-ion battery. A damaged battery can cause an explosion
or fire, and can result in personal injury and/or property damage. To prevent injury or damage: Do not use or charge the battery if it appears to be damaged.
Signs of damage include, but are not limited to, discoloration, warping, and leaking battery fluid.

Power In this chapter: 3 External power Battery safety Battery performance Charging the Lithium-ion batteries Storing the Lithium-ion battery Disposing of
the rechargeable Lithium-ion battery The GPS receiver is powered by an internal Lithium-ion battery, which can be detached from the receiver for charging.
The receiver can also be connected to an external power source through Port 1. During measurement operations, each internal battery typically provides
about 5 hours of power if using the internal Rx (receive) radio and about 4 hours operating as a base station using the internal 450 MHz Tx (transmit) radio.
These times vary according to the type of measurement and the operating conditions.
SPS882 Smart GPS Antenna User Guide 19 3 Batteries and Power External power The GPS receiver uses an external power source in preference to its
internal batteries. If the receiver is not connected to an external power source, or if the external power supply fails, the internal batteries are used. While
carrying out static measurements for postprocessed computations using the internal memory, if no external power is supplied and the internal battery is
drained, the receiver shuts down. No data is lost and when power is restored, the receiver restarts in the same status as it was when power was lost. It is
possible to turn off the internal battery using the web interface.
In this case, when external power is switched off, there is a limited time (30 seconds) before the unit turns off. Battery safety The receiver is powered by one
rechargable Lithium-ion battery. Charge and use the battery only in strict accordance with the instructions in this chapter. C WARNING Do not damage the
rechargeable Lithium-ion battery. A damaged battery can cause an explosion or fire, and can result in personal injury and/or property damage. To prevent
injury or damage: Do not use or charge the battery if it appears to be damaged. Signs of damage include, but are not limited to, discoloration, warping, and
leaking battery fluid. Do not expose the battery to fire, high temperature, or direct sunlight. Do not immerse the battery in water. Do not use or store the
battery inside a vehicle during hot weather.
Do not drop or puncture the battery. Do not open the battery or short-circuit its contacts. WARNING Avoid contact with the rechargeable Lithium-ion
battery if it appears to be leaking. Battery fluid is corrosive, and contact with it can result in personal injury and/or property damage. To prevent injury or
damage: If the battery leaks, avoid contact with the battery fluid. If battery fluid gets into your eyes, immediately rinse your eyes with clean water and seek
medical attention. Do not rub your eyes! If battery fluid gets onto your skin or clothing, immediately use clean water to wash off the battery fluid. C Battery

that it is fully charged before it is stored, and that you charge it at least once every three months while it is stored. Do not allow a battery that is in storage to
discharge to below 5 V. A battery that reaches deep discharge level (5 V or less) cannot be recharged and must be replaced. (To protect a battery that is in
use from deep discharge, the receiver switches power sources or stops drawing power when the battery pack discharges to 5.9 V.) All batteries discharge over
time when not in use, and they discharge faster in colder temperatures. Do not store the receiver at temperatures outside the range 40 °C to +70 °C (40 °F to
+158 °F).
Do not store the batteries in the receiver or in the external charger unless power is applied. Keep all batteries on continuous charge when not in use. You can
keep batteries on charge indefinitely without damage to the batteries. Disposing of the rechargeable Lithium-ion battery Discharge a Lithium-ion battery
before disposing of it. Dispose of batteries in an environmentally sensitive manner, and adhere to any local and national regulations concerning battery
disposal or recycling. 22 SPS882 Smart GPS Antenna User Guide CHAPTER 4 Setup Guidelines In this chapter: 4 Base station operation guidelines Rover
operation guidelines Cellular modem and external radio GPS Real-Time Kinematic (RTK) operation provides centimeter-level accuracy by eliminating errors
that are present in the GPS system. For all RTK, Location RTK, or DGPS operations, you require both a rover receiver and a source of corrections from a
base station or network of base stations. This chapter introduces the concepts of base station and rover operation, provides information to help you identify
good setup locations, describes best practices for setting up the equipment, and outlines the precautions that you need to take to protect the equipment. Note
This chapter provides setup information for all the receivers in the SPS GPS receiver family. SPS882 Smart GPS Antenna User Guide 23 4 Setup Guidelines
Base station operation guidelines A base station consists of a receiver that is placed at a known (and fixed) position.
The receiver tracks the same satellites that are being tracked by the rover receiver, at the same time that the rover is tracking them. Errors in the GPS system
are monitored at the fixed (and known) base station, and a series of position corrections are computed. The messages are sent through a radio link to the
rover receiver, where they are used to correct the real time positions of the rover. Base station components The base station has the following components: · ·
· · GPS receiver GPS antenna Base station radio Power supply GPS receiver and GPS antenna The base station GPS receiver can be one of following types: ·
A Smart GPS antenna, such as the SPS882, which incorporates a GPS receiver, GPS antenna, power supply, and radio into a single compact unit. A Smart
GPS antenna can be rapidly set up on a tripod, fixed height tripod, or T-Bar anywhere that is convenient on the jobsite.
A Modular GPS receiver, such as the SPSx51, which incorporates a GPS receiver, power supply, and radio in a single unit. The GPS antenna (and,
optionally, the base station radio antenna) is separate from the receiver. Because the GPS antenna is separate, you can use the following optimized
components: a geodetic antenna with large ground plane, to eliminate multipath (the major source of GPS errors) at the base station a high-gain or
directional radio antenna, to increase broadcast range and to provide maximum coverage · You can also place a modular GPS receiver in an easily
accessible and secure location, safe from theft and the weather, while the antennas are placed high on a tower or building, clear of obstructions and able to
deliver maximum performance. You can use either type of receiver in a permanent, semi-permanent, or daily quick setup configuration. If semi-permanent or
permanent operation is required, however, the modular receiver delivers significant advantages.
24 SPS882 Smart GPS Antenna User Guide Setup Guidelines 4 Base station setup guidelines For good performance, observe the following base station setup
guidelines: · Place the GPS receiver in a location on the jobsite where equal range in all directions provides full coverage of the site. This is more important
on larger jobsites, where the broadcast range of the base station radio may limit the operations of the GPS system. Place the GPS antenna in a location that
has a clear line of sight to the sky in all directions. Do not place the GPS antenna near vertical obstructions such as buildings, deep cuttings, site vehicles,
towers, or tree canopy. Place the GPS and radio antennas as high as practical. This minimizes multipath from the surrounding area, and enables the radio to
broadcast to the maximum distance. · · Note The GPS antenna must have a clear line of sight to the sky at all times during operation. · Choose the most
appropriate radio antenna for the size and footprint of the site. The higher the gain on the antenna, the longer the range. If there is more focus on the
transmission signal, there is a reduced coverage area.

http://yourpdfguides.com/dref/3225832
A 3 db or 5 db gain antenna provides a mix of good range and reasonable directional coverage. Make sure that the GPS receiver does not lose power. The
GPS receiver has an integrated battery, which has to be charged. To operate continuously for more than a day without loss of power at the base station,
provide external power. Sources of external power include:
AC power 12 V car or truck battery Trimble custom external battery pack Generator power
Solar panel · When you use an external power supply, the integrated battery provides a backup power supply, enabling you to maintain continuous operation
through a mains power failure. When the GPS receiver is connected to a power source greater than 15 V, the integrated battery is continuously charged from
the connected power source. This helps to ensure that the battery stays charged (SPSx51 only). · Do not locate a GPS receiver, GPS antenna, or radio
antenna within 400 meters (about 1,300 feet) of: a powerful radar, television, or cellular communications tower another transmitter another GPS antenna
SPS882 Smart GPS Antenna User Guide 25 4 Setup Guidelines Cell phone towers can interfere with the base station radio broadcast and can stop corrections
from reaching the rover receiver. High-power signals from a nearby radio or radar transmitter can overwhelm the receiver circuits. This does not harm the
receiver, but can prevent the receiver electronics from functioning correctly.
Low-power transmitters, such as those in cell phones and two-way radios, do not interfere with receiver operations. · Do not set up the base station directly
beneath or close to overhead power lines or electrical generation facilities. The electromagnetic fields associated with these utilities can interfere with GPS
receiver operation. Other sources of electromagnetic interference include:
Gasoline engines (spark plugs) Televisions and computer monitors Alternators
and generators Electric motors Equipment with DC-to-AC converters Fluorescent lights Switching power supplies · Place the GPS receivers in a protected
and secure location. If the base station is in the center of a jobsite where heavy machinery is operating, place flags around the base station to warn operators
of its existence.
If you place the SPSx51 Modular GPS receiver in a lock box on the jobsite to protect the receiver from theft or from the weather, shield the lock box from
direct sunlight and provide ventilation for the receiver through an inlet and extractor fan. A receiver that has a broadcast radio generates significant heat. Do
not allow the temperature in the box to exceed 50 ºC (122 ºF). If working in a cold climate, you may need to provide heat to the receiver. Do not operate the
receiver below 40 ºC (40 ºF).
· · Trimble recommends that, wherever possible, you keep GPS receiver equipment dry. The receivers are designed to withstand wet weather, but keeping them
dry prolongs their life and reduces the effects of corrosion on ports and connectors. If the equipment gets wet, use a clean dry cloth to dry the equipment and
then leave the equipment open to the air to dry. Do not lock wet equipment in a transport case for prolonged periods. Avoid exposing the GPS receiver to
corrosive liquids and salt water wherever possible. 26 SPS882 Smart GPS Antenna User Guide Setup Guidelines 4 · Trimble recommends that you install
lightning protection equipment at permanent base station locations. Equipment should include a gas capsule lightning protector in the GPS and radio antenna
feed line and appropriate safety grounding. A static dissipater near the antennas can reduce the likelihood of a direct lightning strike. Also protect any
communications and power lines at building entry points. For more information, contact your local Trimble dealer, or go to the Huber and Suhner website
(www.
hubersuhnerinc.com). Trimble recommends that you use surge protection equipment on all permanently installed equipment. · Rover operation guidelines The
second part of the RTK GPS system is the rover receiver. The rover receiver is mounted on a pole, vehicle, marine vessel, or in a backpack, and is moved
between the points that require measurement or stakeout. The rover receiver is connected to a base station or to a source of RTK corrections such as a virtual
reference station system. The connection is provided by: · · · an integrated radio a cellular modem in the controller an external cellular phone that is
connected to the receiver either by Bluetooth wireless technology or by means of a cable The correction stream for some other positioning solutions, such as
SBAS (WAAS/EGNOS/MSAS), Beacon, and the OmniSTAR service1, is detected by the GPS or combined GPS/Beacon antenna itself. No integrated radio or
base station is required. Rover receiver components The rover receiver has the following components: · · · · GPS receiver GPS antenna Optional integrated
radio receiver and antenna for RTK operations Optional items for the different mounting options (see below) In most rover applications, the receiver operates
entirely from its own integrated battery unit. On a vehicle or on a marine vessel, however, an external power supply can be used.
Use an external power supply if one is provided. The internal battery then acts as a uninterruptible power supply, covering any external power failures. 1.
OmniSTAR is available only with the SPSx51 Modular GPS receivers. SPS882 Smart GPS Antenna User Guide 27 4 Setup Guidelines Choose a rover
receiver according to the needs of the job: · A Smart GPS antenna, such as the SPS882, incorporates the GPS receiver, GPS antenna, power supply, and
receive radio into a single compact unit.
A Smart GPS antenna can be rapidly set up on a pole, vehicle, or backpack. This makes it easy to carry when you are measuring around the jobsite. A
Modular GPS receiver, such as the SPSx51, incorporates the GPS receiver, receive radio, and power supply into a single unit. The GPS antenna and,
optionally, the receive radio antenna, is separate from the receiver. When you use a modular GPS receiver as a rover, you can use optimized components
placed in the best locations for your application.
For example: A small, lightweight rover antenna can be mounted on a pole or backpack; placed in a high, inaccessible location on a marine vessel mast or
cabin; or placed on a site vehicle roof or truck bed. A rubber duck radio antenna, or an external radio antenna, can be mounted on a vehicle or vessel roof to
provide maximum coverage. · A Modular GPS receiver can be placed in a location that is both easily accessible and safe from theft and the weather. The
antennas can be placed high on a vehicle or vessel roof, clear of obstructions and able to deliver maximum performance.

Rover receiver setup guidelines For good rover operation, observe the following setup guidelines: · Place the GPS antenna in a location that has a clear line
of sight to the sky in all directions. Do not place the antenna near vertical obstructions such as buildings, deep cuttings, site vehicles, towers, or tree canopy.
GPS rovers and the base station receive the same satellite signals from the same satellites. The system needs five common satellites to provide RTK
positioning. Place the two GPS antennas at least 2 meters (6.5 feet) apart and at approximately the same height.
Place the GPS and radio antennas as high as possible to minimize multipath from the surrounding area. The receiver must have a clear line of sight to the sky
at all times during operation. · C CAUTION The GPS antenna and its cabling should be installed in accordance with all national and local electrical codes,
regulations, and practices. The antenna and cabling should be installed where they will not become energized as a result of falling nearby power lines, nor be
mounted where they are subjected to overvoltage transients, particularly lightning. Such installations require additional protective means that are detailed in
national and local electrical codes. 28 SPS882 Smart GPS Antenna User Guide Setup Guidelines 4 · GPS satellites are constantly moving. Because you
cannot measure at a specific location now does not mean that you will not be able to measure there later, when satellite coverage at the location improves.
Use GPS planning software to identify the daily best and worst satellite coverage times for your location and then choose measurement times that coincide
with optimal GPS performance. This is especially important when operating in the worst GPS locations. You can download the Trimble Planning software
from the Trimble website (www.
trimble.com/planningsoftware_ts.asp). The SPS882 can track the GPS L2C modernization signal. Additionally, the SPS882 can optionally track the GPS L5
modernization signal and can also track the GLONASS satellite constellation The signals help you to get positions at the worst times of the day and in the
worst GPS locations, but do not guarantee that you will.
To get a fixed position solution with centimeter accuracy, initialize the Precision RTK rover receiver. For initialization to take place, the receiver must track
at least five satellites that the base station is also tracking. In a dual-satellite constellation operation, for example, GPS and GLONASS, the receiver must
track at least six satellites. To maintain a fixed position solution, the rover must continuously track at least four satellites that the base station is also tracking.
In a dual-satellite constellation operation, for example, GPS and GLONASS, the receiver must track at least five satellites.
The radio link between the base and rover receivers must also be maintained. Loss of the satellite signals or loss of the radio link will result in a loss of
centimeter position accuracy. From Fixed, the receiver changes to Float or Autonomous mode: In Float mode, the rover has connection to the base station
through a radio, but has not yet initialized. In Autonomous mode, the rover has lost radio contact with the base station receiver, and is working by itself with
the available GPS signals. · · · · · · On a vehicle or marine vessel, place the GPS antenna in a location as free from shock and vibration as possible. For the
modular GPS receivers, a single magnetic mount is normally sufficient to hold the antenna in a suitable location, whereas for the larger smart antenna, a
triple magnetic mount is normally recommended. Good alternatives include a 5/8" thread bolt in a suitable location on the roof or bull bars, or a doormounted pole bracket. C CAUTION The SPS882 is not suited to on-vehicle operation where it will be subject to heavy vibration, that is, operation in rough
ungraded terrain. Use in these conditions can damage the receiver. · To mount the modular GPS receiver on a pole, use two pole mounting brackets and a
second tripod clip (P/N 571 204 300).
See Figure 4.1. SPS882 Smart GPS Antenna User Guide 29 4 Setup Guidelines Figure 4.1 Rod mount for a modular GPS receiver To mount the modular GPS
receiver on a marine vessel, use the receiver bracket (P/N 56830-00). For marine moving base and heading applications, use the receiver bracket to mount
two receivers together. · Make sure that the rover receiver does not lose power. The batteries in the SPS882 can be changed when flat. (See Chapter 3,
Batteries and Power). If you do not use the rover receiver very often, ensure that it is charged at least every three months. For vehicle operation or marine
vessel operation, Trimble recommends that you use an external power source so that the internal battery can be saved for times when the receiver is being
used off the vehicle or vessel.
Do not locate the receiver or antenna within 400 meters (about 1,300 ft) of powerful radar, television, cellular communications tower, or other transmitters or
GPS antennas. Low-power transmitters, such as those in cellular phones and two-way radios, normally do not interfere with receiver operations. Cellular
communication towers can interfere with the radio and can interfere with GPS signals entering the receiver. This does not harm the receiver, but it can
prevent the receiver electronics from functioning correctly. Do not use the rover receiver directly beneath or close to overhead power lines or electrical
generation facilities.
The electromagnetic fields associated with these utilities can interfere with GPS receiver operation. Other sources of electromagnetic interference include:
gasoline engines (spark plugs) · · 30 SPS882 Smart GPS Antenna User Guide Setup Guidelines 4
· televisions and computer monitors alternators and
generators electric motors equipment with DC-to-AC converters fluorescent lights switching power supplies Trimble recommends that, wherever possible, all
GPS receiver equipment is protected from rain or water. Although, the receivers are designed to withstand all wet weather conditions, keeping the receivers
dry prolongs the life of the equipment and reduces the effects of corrosion on ports and connectors. If the equipment gets wet, use a clean dry cloth to dry the
equipment and then leave the equipment open to the air to dry. Do not lock wet equipment in a transport case for prolonged periods.
Wherever possible, avoid exposing the GPS receiver to corrosive liquids and salt water. If you are using the rover receiver in open spaces, Trimble
recommends that you stop work during electrical storms where the risk of lightning strike is high. Where cables are involved, Trimble recommends that you
use cable ties to secure the cables to the rod or other equipment to avoid inadvertent snagging while moving about the jobsite.

Be careful not to kink, twist, or unnecessarily extend cables, and avoid trapping them in vehicle doors or windows. Damage to cables can reduce the
performance of GPS equipment. · · Internal radio setup for rover operations The internal radio of the receiver is delivered with the transmit (Tx) radio
frequencies preprogrammed into the receiver. To add receive (Rx) radio frequencies to 450 MHz radios, use the WinFlash utility or web interface (see
Appendix C, Adding UHF Internal Radio Frequencies). Network channels can be selected for the 900 MHz radios. Once the radio frequencies are configured,
use the controller or receiver to select channel frequencies during base station or rover setup operations. Cellular modem and external radio Instead of the
internal radio, you can use a cellular modem or an external radio as your data communications link.
To connect a cellular modem to a Smart GPS antenna, you need the following: · · Smart GPS antenna One of the following: A Trimble Tablet or TSC2
controller with an internal cellular modem Cellular modem or a cellular phone that can transmit data SPS882 Smart GPS Antenna User Guide 31 4 Setup
Guidelines · · Serial (cell phone to DB9) cable (supplied with the cellular modem or phone). Port 2 of the Smart GPS antenna supports full RS-232 protocol,
and should function properly with most cell phone cables. Some cellular units may require custom cabling. Alternatively, the receiver also supports a cablefree Bluetooth connection with Bluetooth-enabled cell phones. For more information on using a cellular modem as a data link, refer to the SCS900 Site
Controller Software Office Guide. 32 SPS882 Smart GPS Antenna User Guide CHAPTER 5 Setting up the Receiver In this chapter: 5 Connecting the receiver
to external devices Common ways to set up a base station Common ways to set up a rover receiver In this chapter, recommendations for setting up the
receiver as a base station or for rover operations are provided. The recommendations cover a variety of common use scenarios. Note This chapter provides
setup information for all the receivers in the SPS GPS receiver family. SPS882 Smart GPS Antenna User Guide 33 5 Setting up the Receiver Connecting the
receiver to external devices You can connect a Smart GPS antenna to the following devices: · · a Trimble controller running the Trimble SCS900 Site
Controller software an external radio-modem Trimble controller with SCS900 Site Controller software You can operate an SPS GPS receiver with any
Trimble controller, for example, a TSC2® or Trimble CU controller, that is running the SCS900 software. Typically, the receiver and the controller operate
from their own individual power sources.
The receiver and controller can communicate through Bluetooth wireless technology and can be connected without a cable. However, if a cable is required,
Table 5.1 shows how to connect the cables for each combination of SPS GPS receiver and Trimble controller. Table 5.1 Connecting to a Trimble controller

indicates that the radio transmits corrections. "Rx" indicates that the receiver receives corrections. "Tx/Rx" indicates that the radio both transmits and
receives corrections.
If the Smart GPS antenna does not have an internal transmit radio, or you want to connect to a higher powered external transmit radio or cellular modem,
use the DB9 port, the Lemo port, or Bluetooth wireless technology. 34 SPS882 Smart GPS Antenna User Guide Setting up the Receiver 5 The SPS882 Smart
GPS antenna supports the following Trimble base radios: · · · · · · SiteNetTM 450 TRIMMARK 3 TRIMTALKTM 450 Trimble SNB900 Trimble PDL450
Trimble HPB450 The Smart GPS antenna also supports third-party transparent radios and third-party cellular modems. To use an external radio with the
Smart GPS antenna, you need an external power source for the radio--except for the SNB900 radio, which contains an internal battery. To configure the
radio modem separately, use the external radio's configuration program, or display and keypad. Common ways to set up a base station You can set up a base
station in different ways depending on the application, coverage area, degree of permanence versus mobility, and available infrastructure. Before you set up a
base station, please read Appendix 4, Setup Guidelines. Setting up a base station for permanent or semi-permanent installation For construction applications,
where machine and site positioning operations using GPS will be carried out over a long time (weeks, months, or years), ensure that you choose the base
station location carefully. A semi-permanent or permanent base station helps to eliminate the types of error that can result from repeated daily setups, and
ensures that you always use the GPS antenna at the exact original location. The requirement for a permanent base station setup increases as more receivers
that use the base station as a source of corrections, increases the cost of any base station downtime. On the largest jobsites, and on those that remain
operational for the longest time, a permanent or semi-permanent installation is a popular solution.
A modular GPS receiver is typically used as the base station, located in a site office or trailer where it is easy to access (to check or configure), and where it
is secure from theft and the weather. The GPS and radio antennas are normally mounted on a permanent structure on the roof of the building, where they are
high and clear from obstructions and where the radio antenna can provide the maximum range of operation. SPS882 Smart GPS Antenna User Guide 35 5
Setting up the Receiver Trimble recommends that you use the Trimble Zephyr GeodeticTM Model 2 GPS antenna. This antenna has a large ground plane that
reduces multipath, providing the best GPS performance at the base location. The antennas are connected to the receiver by high quality RF cables.
The receiver is connected to a permanent power supply (mains or generator power). The internal battery of the receiver is always being charged, and acts as
an uninterruptible power supply if there is a power failure.
