WARRANTY DISCLAIMER. EXCEPT AS EXPRESSLY SET OUT IN THIS AGREEMENT, HEMISPHERE MAKES NO
REPRESENTATION, WARRANTY OR CONDITION OF ANY KIND TO LICENSEE, WHETHER VERBAL OR WRITTEN
AND HEREBY DISCLAIMS ALL REPRESENTATIONS, WARRANTIES AND CONDITIONS OF ANY KIND INCLUDING
FITNESS FOR A PARTICULAR PURPOSE, MERCHANTABILITY, ACCURACY, RELIABILITY OR THAT THE USE OF THE
SOFTWARE WILL BE UNINTERRUPTED OR ERROR-FREE AND HEREBY DISCLAIMS ALL REPRESENTATIONS,
WARRANTIES AND CONDITIONS ARISING AS A RESULT OF CUSTOM, USAGE OR TRADE AND THOSE ARISING
UNDER STATUTE.
LIMITS ON WARRANTY DISCLAIMER. Some jurisdictions do not allow the exclusion of implied warranties or
conditions, so some of the above exclusions may not apply to Licensee. In that case, any implied warranties or
conditions which would then otherwise arise will be limited in duration to ninety (90) days from the date of the
license of the Software or the purchase of the Product. The warranties given herein give Licensee specific legal rights
and Licensee may have other rights which may vary from jurisdiction to jurisdiction.
CHANGE TO WARRANTY. No employee or agent of Hemisphere is authorized to change the warranty provided or
the limitation or disclaimer of warranty provisions. All such changes will only be effective if pursuant to a separate
agreement signed by senior officers of the respective parties.
WARRANTY CLAIM. In the event Licensee has a warranty claim Licensee must first check for and install all
Updates that are made available. The warranty will not otherwise be honored. Proof of purchase may be required.
Hemisphere does not honor claims asserted after the end of the Warranty Period.
LICENSEE REMEDIES. In all cases which involve a failure of the Software to conform in any material respect to the
documentation during the Warranty Period or a breach of a warranty, Hemisphere's sole obligation and liability, and
Licensee's sole and exclusive remedy, is for Hemisphere, at Hemisphere's option, to (a) repair the Software, (b)
replace the Software with software conforming to the documentation, or (c) if Hemisphere is unable, on a
reasonable commercial basis, to repair the Software or to replace the Software with conforming software within
ninety (90) days, to terminate this Agreement and thereafter Licensee shall cease using the Software. Hemisphere
will also issue a refund for the price paid by Licensee less an amount on account of amortization, calculated on a
straight-line basis over a deemed useful life of three (3) years.
LIMITATION OF LIABILITY. IN NO EVENT WILL HEMISPHERE BE LIABLE TO LICENSEE FOR ANY INCIDENTAL,
CONSEQUENTIAL, SPECIAL OR INDIRECT DAMAGES INCLUDING ARISING IN RELATION TO ANY LOSS OF DATA,
INCOME, REVENUE, GOODWILL OR ANTICIPATED SAVINGS EVEN IF HEMISPHERE HAS BEEN INFORMED OF THE
POSSIBILITY OF SUCH LOSS OR DAMAGE. FURTHER, IN NO EVENT WILL HEMISPHERE'S TOTAL CUMULATIVE
LIABILITY HEREUNDER, FROM ALL CAUSES OF ACTION OF ANY KIND, EXCEED THE TOTAL AMOUNT PAID BY
LICENSEE TO HEMISPHERE TO PURCHASE THE PRODUCT. THIS LIMITATION AND EXCLUSION APPLIES
IRRESPECTIVE OF THE CAUSE OF ACTION, INCLUDING BUT NOT LIMITED TO BREACH OF CONTRACT,
NEGLIGENCE, STRICT LIABILITY, TORT, BREACH OF WARRANTY, MISREPRESENTATION OR ANY OTHER LEGAL
THEORY AND WILL SURVIVE A FUNDAMENTAL BREACH.
LIMITS ON LIMITATION OF LIABILITY. Some jurisdictions do not allow for the limitation or exclusion of liability for
incidental or consequential damages, so the above limitation or exclusion may not apply to Licensee and Licensee
may also have other legal rights which may vary from jurisdiction to jurisdiction.
BASIS OF BARGAIN. Licensee agrees and acknowledges that Hemisphere has set its prices and the parties have
entered into this Agreement in reliance on the limited warranties, warranty disclaimers and limitations of liability set
forth herein, that the same reflect an agreed-to allocation of risk between the parties (including the risk that a
remedy may fail of its essential purpose and cause consequential loss), and that the same forms an essential basis
of the bargain between the parties. Licensee agrees and acknowledges that Hemisphere would not have been able
to sell the Product at the amount charged on an economic basis without such limitations.
PROPRIETARY RIGHTS INDEMNITY. Hemisphere shall indemnify, defend and hold harmless Licensee from and
against any and all actions, claims, demands, proceedings, liabilities, direct damages, judgments, settlements, fines,
penalties, costs and expenses, including royalties and attorneys' fees and related costs, in connection with or arising
out of any actual infringement of any third party patent, copyright or other intellectual property right by the Software
or by its use, in accordance with this Agreement and documentation, PROVIDED THAT: (a) Hemisphere has the right
to assume full control over any action, claim, demand or proceeding, (b) Licensee shall promptly notify Hemisphere
of any such action, claim, demand, or proceeding, and (c) Licensee shall give Hemisphere such reasonable
assistance and tangible material as is reasonably available to Licensee for the defense of the action, claim, demand
or proceeding. Licensee shall not settle or compromise any of same for which Hemisphere has agreed to assume
responsibility without Hemisphere's prior written consent. Licensee may, at its sole cost and expense, retain
separate counsel from the counsel utilized or retained by Hemisphere.
INFRINGEMENT. If use of the Software may be enjoined due to a claim of infringement by a third party then, at its
sole discretion and expense, Hemisphere may do one of the following: (a) negotiate a license or other agreement so
that the Product is no longer subject to such a potential claim, (b) modify the Product so that it becomes noninfringing, provided such modification can be accomplished without materially affecting the performance and
functionality of the Product, (c) replace the Software, or the Product, with non-infringing software, or product, of
equal or better performance and quality, or (d) if none of the foregoing can be done on a commercially reasonable
basis, terminate this license and Licensee shall stop using the Product and Hemisphere shall refund the price paid by
Licensee less an amount on account of amortization, calculated on a straight-line basis over a deemed useful life of
three (3) years.
The foregoing sets out the entire liability of Hemisphere and the sole obligations of Hemisphere to Licensee in
respect of any claim that the Software or its use infringes any third party rights.

Overview
You can use the H320 for any application
needing accurate heading or DGPS or RTK
positioning. Fitted with Hemisphere GPS’
patented Eclipse receiver technology, the
H320 computes heading and position using
two antennas. This design provides precise
heading and GPS sub-meter positioning
accuracy while stationary. And with
integrated SBAS support, you can receive
precision guidance anywhere those services
are available.
i.
3.
The H320 provides accurate, reliable
heading and position information at high
update rates. It does this by using a high performance GNSS engine for signal
processing.
The one receiver processes information from both the primary GPS antenna and
secondary GPS antenna. Positions computed by the H320 are referenced to the phase
center of the primary GPS antenna. Heading data references the vector formed from
the primary GPS antenna phase center to the secondary GPS antenna phase center.

Chapter 1: Introduction
Configuring the H320
The H320 has four communication ports: A, B, C, and D. Ports A, B, and C are fully
independent and can have different messages output at different rates. You can
configure each of these ports for external correction input or output binary message
information or RTCM corrections from an outside source. You can also configure the
output of ports A, B, or C through any of these ports. Configure the baud rates if
necessary; the default is 19200 for Ports A, B, and C.
Port D is reserved for RTCM differential corrections and may be used by the
Hemisphere GPS SBX-4™ board.
Configure the supplementary sensors if necessary. The tilt sensor operates by default
and the gyro is disabled but it is recommended that all sensors be turned on once
installation is complete.
Configure for your mode of differential operation: SBAS, beacon, or external
corrections.
NMEA 0183 Message Interface
The H320 uses a NMEA 0183 interface, allowing you to easily make configuration
changes by sending text-type commands to the receiver. For more information on
NMEA 0183 commands and messages refer to the Hemisphere GPS Technical
Reference (go to www.hemispheregps.com/support and click the GPS Reference icon).
Binary Message Interface
In addition to the NMEA 0183 interface, the H320 also supports a selection of binary
messages. There is a wider array of information available through the binary
messages, plus binary messages are inherently more efficient with data. If the
application has a requirement for raw measurement data, this information is available
only in a binary format. For more information on binary messages refer to the
Hemisphere GPS Technical Reference (go to www.hemispheregps.com/support and
click the GPS Reference icon).

Chapter 2: Board Overview
Mounting Options
There are two options for mounting the H320:
•
Direct Electrical Connection method
•
Indirect Electrical Connection (Cable) method
Direct Electrical Connection Method
Place an RF connector, heading connector, and mounting holes on the carrier board
and then mount the H320 on the standoffs and RF and header connectors. This
method is very cost effective as it does not use cable assemblies to interface the H320.
Note: Be aware of the GPS RF signals present on the carrier board and ensure the
correct standoff height to avoid any flexual stresses on the board when you fasten it
down.
The H320 uses a standoff height of 7.9 mm (0.3125 in). With this height there should
be no washers between either the standoff and the H320 or the standoff and the
carrier board; otherwise, you must make accommodations. You may need to change
the standoff height if you select a different header connector.
If you want to use a right angle MCX connector, use a taller header than the Samtec
part number suggested in this guide. This will provide clearance to have a right angle
cable-mount connector and reduce the complexity by not having the carrier board
handle the RF signals. See Table 2-1 on page 7 for H320 connector information.
Appendix C: Technical Specifications
The mounting holes of the H320 have a standard inner diameter of 3.2 mm (0.125 in).
Indirect Electrical Connection (Cable) Method
The second method is to mount the H320 mechanically so you can connect a ribbon
power/data cable to the H320. This requires cable assemblies and there is a reliability
factor present with cable assemblies in addition to increased expense.

Header and Pinouts
The H320 uses a dual-row header connector to interface with power, communications,
and other signals.
To identify the first header pin orient the board so the diamond is to the upper left of
the pins; the first pin is on the left directly below the diamond (see Figure 2-2). The
pins are then sequentially numbered per row from top to bottom.

Chapter 2: Board Overview
Signals
This section provides information on the signals available via connectors.
RF Input
The H320 is designed to work with active GPS antennas with an LNA gain range of 10
to 40 dB. The purpose of the range is to accommodate for losses in the cable system.
Essentially, there is a maximum cable loss budget of 30 dB for a 40 dB gain antenna.
Depending on the chosen antenna, the loss budget will likely be lower (a 24 dB gain
antenna would have a 14 dB loss budget).
When designing the internal and external cable assemblies and choosing the RF
connectors, do not exceed the loss budget; otherwise, you will compromise the
tracking performance of the H320.
Serial Ports
The H320 has four serial communication ports:
•
Port A, Port B, Port C - main ports
•
Port D - Exclusively used to interface with Hemisphere GPS’ SBX-4 beacon
board or an external corrections source. This port will not output normal
GPS-related NMEA messages. When communicating into either Port A, B, or
C, a virtual connection may be established to the device on Port D using the
$JCONN command. See “Communication Port D” below for more
information on Port D.
Appendix B: Troubleshooting
The H320 serial ports’ 3.3 V CMOS signal level can be translated to interface with
other devices. For example, if serial Ports A, B, and/or C are used to communicate to
external devices such as PCs, you must translate the signal level from 3.3 V CMOS to
RS-232.
Communication Port D
Port D is exclusively for external DGPS correction input to the H320, such as from
Hemisphere GPS’ SBX-4 beacon board.
USB Ports
The H320 has one USB device port and one USB host port, where:
•
USB Device port (data communication) shown in Figure 2-3 on page 13
serves as a high speed data communications port, such as for a PC
•
USB Host port (data storage) shown in Figure 2-4 on page 14 serves as a
data storage port, such as with a USB flash drive
The USB data lines are bi-directional and are differential pairs. The USB data lines
should be laid out on printed wire board (PWB) with 90 : ±15% differential
impedance. The traces should be over a solid continuous ground plane. Maintain
parallel traces and symmetry. There shall be no traces or breaks in the ground plane
underneath the D+ and D- traces. It is also recommended to leave a minimum 20 mil
spacing between USB signals and other signals. Treat the data lines as if they are RF
signals.

Appendix A: Frequently Asked Questions
Chapter 2: Board Overview
External Corrections
LED Indicators
My H320 system does not appear to be using DGPS or RTK corrections from
an external correction source. What could be the problem?
The H320 features the following surface-mounted diagnostic LEDs that indicate board
status (see Figure 2-5):
•
PWR - Power
•
PGPS - Primary GPS lock
•
SGPS - Secondary GPS lock
•
DIFF - Differential lock
Verify the baud rates used by the H320 match that of the external correction
source.
•
DGPS - DGPS position
•
HDG - Heading lock
•
The external correction should be using an 8 data bit, no parity, 1 stop bit
(8-N-1) serial port configuration.
•
L-BAND - L-band lock
•
Inspect the cable connection to ensure there is no damage.
•
Check the pinout information for the cables to ensure the transmit line of the
external correction source is connected to the receive line of the H320 serial
port and that the signal grounds are connected.
•
Make sure the H320 has been set to receive external corrections by issuing
the $JDIFF command. Refer to the Hemisphere GPS Technical Reference (go
to www.hemispheregps.com/support and click the GPS Reference icon) for
more information.
This could be due to a number of factors. To isolate the issue:
•
Make sure DGPS corrections are RTCM v2.3 protocol.
•
Make sure RTK corrections are either ROX, RTCM v3, CMR, or CMR+
protocol.
•
Installation
Does it matter where I mount the H320’s antenna?
Yes, the mounting location must provide a clear view of the sky for satellite tracking.
Additionally, the position that it computes is based on the center of the antenna. It
should be placed in the location for which the user would like a position. Often
antennas are mounted on the centerline of a vehicle or on a pole-mount for
georeference.
How will the antenna selection and mounting affect H320 performance?
For best results select a multipath-resistant antenna. Ensure the antenna tracks all the
available signals for the receiver.
Mount the antenna:
•
With the best possible view of the sky
•
In a location with the lowest possible multipath
Using a magnetic mount for the antenna will not affect performance.
Figure 2-5: Onboard LEDs
With the exception of the power LED the signals that drive the LEDs are available via
the header connector. Refer to Table 2-2 on page 9 for pin number descriptions for the
H320.
Note: Each signal pin can offer only 1 mA of current and is active low. Since 1 mA of
current may be inadequate for the application, you may want to transistor-buffer these
signals to provide more current capacity for acceptable LED luminance.
1PPS Timing Signal
The one pulse per second (1 PPS) timing signal is used in applications where devices
require time synchronization.
Note: 1 PPS is typical of most GPS boards but not essential to normal receiver
operation. Do not connect this pin if you do not need this function.
The 1 PPS signal is 3.3 V CMOS, active low with falling edge synchronization. The
1 PPS signal is capable of driving a load impendance greater than 10 k: in parallel
with 10 pF. The pulse is approximately 1 ms.
Event Marker Input
A GPS solution may need to be forced at a particular instance, not synchronized with
GPS time depending on the application, such as indicating to the GPS receiver when a
photo is taken from a camera used for aerial photography.
Note: Event marker input is typical of most GPS boards but not essential to normal
receiver operation. Do not connect this pin if you do not need this function.

The event marker input is 3.3 V CMOS, active low with falling edge synchronization.
The input impedance and capacitance is higher than 10 k: and 10 pF, respectively,
with a threshold of lower than 0.7 V required to recognize the input.
Grounds
You must connect all grounds together when connecting the ground pins of the H320.
These are not separate analog and digital grounds that require separate attention.
Refer to Table 2-2 on page 9 for pinout ground information for the H320.
Note: Speed radar output is not essential to normal receiver operation. Do not
connect these pins if you do not need this function.
The following two pins on the H320 relate to the Speed Radar.
•
How do I know if the H320 has acquired an SBAS signal?
The H320 outputs the $RD1 message that contains the SBAS bit error rate (BER) for
each SBAS channel. The BER value describes the rate of errors received from SBAS.
Ideally, this should be zero. However, the H320 performs well up to 150 BER. The
SLXMon and PocketMax utilities provide this information without needing to use
NMEA commands.
How do I know if the H320 is offering a differentially-corrected or
RTK-corrected position?
Speed Radar Output
•
SBAS Reception and Performance
Speed Radar Pulse (pin 19) - Outputs a square wave with 50% duty cycle. The
frequency of the square wave varies directly with speed. 97 Hz represents a
speed of 1 m/s (3.28 ft/s).
Speed Radar Ready Signal (pin 20) - Indicates when the speed signal on the
‘Speed Radar Pulse’ pin is valid. In static situations, such as when the vehicle
has stopped, the GPS position may still have slight variations from one
moment to the next. During these instances, the signal on the ‘Speed Radar
Ready Signal’ pin is ‘high’ or +Vcc, indicating the speed coming out of the
‘Speed Radar Pulse’ pin is erroneous and not truly indicative of the GPS
receiver’s actual speed. Therefore, it should not be referred to or be
used. Once the vehicle starts moving again and meets a minimum threshold
speed, the output on the ‘Speed Radar Ready Signal’ pin will go ‘low’
indicating valid speed information is present on the ‘Speed Radar Pulse’ pin.
Note: Neither pin 19 nor 20 has any form of isolation or surge protection. If utilizing
the Speed Radar Pulse output, Hemisphere GPS strongly recommends incorporating
some form of isolation circuitry into the supporting hardware. Contact Hemisphere
GPS Technical Support for an example of an optically isolated circuit.
The H320 outputs the $GPGGA message as the main positioning data message. This
message contains a quality fix value that describes the GPS status. If this value is 2,
the position is differentially corrected; if this value is 5, the position is RTK-corrected.
The SLXMon and PocketMax utilities provide this information without needing to use
NMEA commands.
How do I select an SBAS satellite?
By default the H320 will automatically attempt to track the appropriate SBAS satellites.
If multiple satellites are available, the one with the lowest BER value is selected to be
used to decode the corrections.
You can manually select which SBAS satellites to track (refer to the Hemisphere GPS
Technical Reference—go to www.hemispheregps.com/support and click the GPS
Reference icon—for more information); however, this is not recommended.
Should I be concerned if the H320 is frequently losing lock on SBAS due to
obstructions or low satellite elevation angles at my geographic location?
No, provided that the receiver is receiving a full set of corrections relatively often.
Using COAST technology, the H320 is able to perform well for 40 minutes or more
with aging correction data. Similar to DGPS corrections, accuracy degrades over time
and distance. To obtain a full set of corrections the H320 antenna receives the
ionospheric map over a period of a few minutes. This is the minimum amount of time
required to get a full set of corrections for SBAS operation. After this, the receiver can
coast until the next set of corrections have been received.
Accuracy is a function of correction age and current ionospheric activity, which will
increase in the coming years.
Do I need a dual frequency antenna for SBAS?
Hemisphere GPS recommends using a dual frequency antenna with the H320. While
some receiver function is possible with an L1-only antenna, full receiver performance
will only be realized with a dual frequency antenna.

Chapter 2: Board Overview
Shielding
How do I change the baud rate of a port from that port?
Connect at the current baud rate of the H320 port and then issue a $JBAUD command
to change the port baud rate to the desired rate. Now change the baud rate in your
application to the desired rate.
What is the best software tool to use to communicate with the H320 and
configure it?
Receiver Mounting
Hemisphere GPS uses three different software applications:
•
•
•
The H320 is a sensitive instrument. When integrated into an enclosure, the H320
requires shielding from other electronics to ensure optimal operation. The H320 shield
design consists of a thin piece of metal with specific diameter holes, preventing
harmful interference from penetrating, while still allowing air circulation for cooling.
HyperTerminal™ - Available on all Windows® 95, 98, ME, and XP. This tool
allows you to configure the H320 by directly typing commands into the
terminal window. The output from the H320 is simultaneously shown. When
using HyperTerminal, ensure it is configured to use the correct PC
communication port and baud rate, and that the local echo feature is on (to
see what is being typed).
SLXMon - Available at www.hemispheregps.com. This application is a very
useful tool for graphically viewing tracking performance and position
accuracy, and for recording data. It can also configure message output and
port settings. SLXMon runs on Windows 95 or higher.
PocketMax - Available at www.hemispheregps.com. Similar to SLXMon, you
can use this application to graphically view tracking performance and
position accuracy, record data, and configure message output and port
settings. PocketMax runs on multiple Windows platforms using the
Windows .NET framework.
GPS Reception and Performance
How do I know what the H320 is doing?
The H320 supports standard NMEA data messages. The $GPGSV and Bin99 data
messages contain satellite tracking and SNR information. If available, the computed
position is contained in the $GPGGA message. Additionally, the H320 has surfacemounted status LEDs that indicate receiver status.
The H320 is a precision instrument. To ensure optimal operation, consider mounting
the receiver in a way to minimize vibration and shock.
When mounting the H320 immediately adjacent to the GPS antenna, Hemisphere GPS
highly recommends shielding the board from the LNA of the antenna. This step can be
more complex than some integrators initially estimate. Attempt to confirm the
operation in your application as early in the project as possible.
Thermal Concerns
The H320 receiver consumes a few watts of power, which ultimately will generate
heat. Since this may raise the ambient temperature inside an enclosure consider
managing the heat inside the enclosure to ensure the internal temperature does not
exceed the maximum operating temperature for the H320. Some suggestions for heat
management are heat sinks, heat conductive foam, or using a small cooling fan
possibly using a thermal switch. Air moving over the H320 removes heat very
effectively.
Note: Thermal design may only be a concern if the integrated product’s maximum
design temperature is expected to be close to that of the H320.
Do I have to be careful when using the H320 to ensure it tracks properly?
For best performance, the H320’s antenna must have a clear view of the sky for
satellite tracking. The H320 can tolerate a certain amount of signal blockage because
redundant satellites are often available. Only four satellites are required for a position;
however, the more satellites that are used, the greater the positioning accuracy.

Appendix A: Frequently Asked Questions
Power, Communication, and Configuration
My H320 system does not appear to be communicating. What do I do?
This could be one of a few issues:
•
Examine the H320 cables and connectors for signs of damage or offset.
•
Ensure the H320 system is properly powered with the correct voltage.
•
Ensure there is a good connection to the power supply since it is required to
terminate the power input with the connector.
•
Check the documentation of the receiving device, if not a PC, to ensure the
transmit line from the H320 is connected to the receive line of the other
device. Also, ensure the signal grounds are connected.
•
If the H320 is connected to a custom or special device, ensure the serial
connection to it does not have any incompatible signal lines present that
prevent proper communication.
•
Make sure the baud rate of the H320 matches the other device. The other
device must also support an 8 data bit, 1 stop bit, no parity port
configuration (8-N-1). Some devices support different settings that may be
user configurable. Ensure the settings match.
•
Consult the troubleshooting section of the other device’s documentation to
determine if there may be a problem with the equipment.
Am I able to configure two serial ports with different baud rates?
Yes, all the ports are independent. For example, you may set one port to 4800 and
another port to 19200.
Am I able to have the H320 output different NMEA messages through
multiple ports?
Yes, different NMEA messages can be sent to the serial ports you choose. These
NMEA messages may also be at different update rates.
A high enough baud rate is needed to transmit all the data; otherwise, some data may
not be transmitted.
How can I determine the current configuration of the H320?
The $JSHOW command will request the configuration information from the H320. The
response will be similar to:
$>JSHOW,BAUD,19200
$>JSHOW,BIN,1,5.0
$>JSHOW,BAUD,4800,OTHER
$>JSHOW,ASC,GPGGA,1.0,OTHER
$>JSHOW,ASC,GPVTG,1.0,OTHER
$>JSHOW,ASC,GPGSA,1.0,OTHER
How can I be sure the configuration will be saved for the subsequent power
cycle?
Query the receiver to make sure the current configuration is correct by issuing a
$JSHOW command. If not, make the necessary changes and reissue the $JSHOW
command. Once the current configuration is acceptable, issue a $JSAVE command
and wait for the receiver to indicate the save is complete. Do not power off the
receiver until the “save complete” message appears.

Appendix A: Frequently Asked Questions
Integration
Do I need to use the 1 PPS and event marker?
No, these are not necessary for H320 operation.
What should I do with the 1 PPS signal if I do not want to use it?
This signal will be strobing at 1 Hz, so it should not be connected.
What should I do with the manual mark input if I am not going to use it?
Do not connect the pin because this signal is active low.
Do I need to use the lock indicators?
No, these are present for applications where it is desirable to have an LED visible to
the user. These signals need to be transistor-buffered, as these lines can only offer
1 mA. Depending on the product and the application, LEDs can be very useful to the
end user. These signals are active low.
Do I need to use a shield-can for the H320?
Not necessarily...but you may need to if there are RF interference issues, such as if the
H320 interferes with other devices. A shield-can would be a good start in terms of
investigating the benefit. If you are designing a smart antenna system, one is likely
needed. Hemisphere GPS recommends that you always conduct an RF prescan when
integrating OEM boards.
Chapter 3: Operation
Powering the H320
If my company wishes to integrate this product, what type of engineering
resources will I need to do this successfully?
Communicating with the H320
Hemisphere GPS recommends you have sufficient engineering resources with the
appropriate skills in and understanding of the following:
•
Electronic design (including power supplies and level translation)
•
RF implications of working with GPS equipment
•
Circuit design and layout
•
Mechanical design and layout
Configuring the H320
Firmware
Configuring the Data Message Output
Saving the H320 Configuration
Using Port D for RTCM Input
Configuration Defaults
What type of assistance can I expect from Hemisphere GPS when
integrating the H320?
Integration of a GPS board has such benefits as:
•
Lower system cost
•
Improved branding (rather than relabeling an existing product)
•
Better control of system design
As an integrator, you are responsible for ensuring that the correct resources are in
place to technically complete the integration. Hemisphere GPS will provide
reasonable assistance; however, Hemisphere GPS does not have dedicated
engineering resources for in-depth integration support. Hemisphere GPS will do its
best to provide support as necessary, but you should expect to have reasonable
expertise to use this Integrators Guide.

Chapter 3: Operation
This chapter provides H320 operation information, such as communicating with the
H320, firmware, and configuration defaults.
Note: Install your antenna outdoors so it has a clear view of the entire sky. If you
place the antenna indoors near a window, for example, you will likely not track a
sufficient number of satellites. With a properly installed antenna the H320 provides a
position within approximately 60 sec.
Powering the H320
The H320 is powered by a 3.3 VDC power source. Once you connect appropriate
power the H320 is active. Although the H320 proceeds through an internal startup
sequence upon application of power, it is ready to communicate immediately.
Communicating with the H320
The H320 features three primary serial ports (Port A, Port B, Port C) that you can
configure independently from each other. You can configure the ports for any
combination of NMEA 0183, binary, and RTCM SC-104 data. The usual data output is
limited to NMEA data messages as these are industry standard.
Note: You may use the three serial ports to separate the different data types and
output different rates. If the H320 is required to output different data types
simultaneously, ensure data logging and the processing software used can correctly
parse the different data from a single stream.

The software that runs the H320 is often referred to as firmware since it operates at a
low level. You can upgrade the firmware in the field through any serial port as new
versions become available.
You can have two firmware applications loaded on the receiver; however, you can
only operate one at a time.
The H320 currently ships with the rover RTK application and the base RTK/SBAS
application. Refer to the Hemisphere GPS Technical Reference (go to
www.hemispheregps.com/support and click the GPS Reference icon) for information
on the $JAPP command, which you use to change between the two H320 applications.
Configuring the Data Message Output
The H320 features three primary bi-directional ports (Ports A, B and C) and a
differential-only port (Port D). You can configure messages for all ports by sending
proprietary commands to the H320 through any port. For a complete list of commands
and messages refer to the Hemisphere GPS Technical Reference (go to
www.hemispheregps.com/support and click the GPS Reference icon).
‘THIS’ Port and the ‘OTHER’ Port
Both Port A and Port B use the phrases “THIS” and “OTHER” when referring to
themselves and each other in NMEA messages.
‘THIS’ port is the port you are currently connected to for inputting commands. To
output data through the same port (‘THIS’ port) you do not need to specify 'THIS' port.
For example, when using Port A to request the GPGGA data message be output at
5 Hz on the same port (Port A), issue the following command:
$JASC,GPGGA,5<CR><LF>
The ‘OTHER’ port is either Port A or Port B, whichever one you are not using to issue
commands. If you are using Port A to issue commands, then Port B is the ‘OTHER’
port, and vice versa. To specify the ‘OTHER’ port for the data output you need to
include 'OTHER' in the command. For example, if you use Port A to request the
GPGGA data message be output at 5 Hz on Port B, issue the following command:
$JASC,GPGGA,5,OTHER<CR><LF>
When using Port A or Port B to request message be output on Port C, you must
specifically indicate (by name) you want the output on Port C. For example, if you use
Port A to request the GPGLL data message be output at 10 Hz on Port C, issue the
following command:
$JASC,GPGLL,10,PORTC<CR><LF>

Saving the H320 Configuration
Configuration Defaults
Each time you change the H320’s configuration you may want to save it so you do not
have to reconfigure the receiver each time you power it on. To save the configuration,
issue the $JSAVE command to the Eclipse using a terminal program such as
HyperTerminal or either of Hemisphere GPS’ applications (SLXMon or PocketMax).
The H320 will take approximately five seconds to save the configuration to nonvolatile memory and will indicate when the configuration has been saved. Refer to the
Hemisphere GPS Technical Reference (go to www.hemispheregps.com/support and
click the GPS Reference icon) for more information on the $JSAVE command.
Below is the standard configuration for the H320. For more information on these
commands refer to the Hemisphere GPS Technical Reference (go to
www.hemispheregps.com/support and click the GPS Reference icon).
Using Port D for RTCM Input
Port D has been optimized to interface with Hemisphere GPS’ SBX-4 beacon board
and operates at 9600 baud (8 data bits, no parity and 1 stop bit – 8-N-1).
To configure the H320 to use Port D, issue the following command:
$JDIFF,BEACON<CR><LF>
To return to using SBAS as the correction source, send the following command to the
H320:
$JDIFF,WAAS<CR><LF>
For a complete list of commands and messages refer to the Hemisphere GPS
Technical Reference (go to www.hemispheregps.com/support and click the GPS
Reference icon).
