mitigates the impact of land-based communication instability.

Powered by Hemisphere’s Atlas L-band system service, aRTK augments the
ability to maintain an RTK solution when the original RTK data link is lost or
interrupted. The aRTK provides an additional layer of communication
redundancy to RTK users, assuring that productivity is not impacted by
intermittent data connectivity.

H328 receives aRTK augmentation correction data over satellite, while also
receiving the land- based RTK correction data. The receiver internally
operates with two sources of RTK correction, creating one additional layer of
correction redundancy as compared to typical RTK systems.

After a few seconds of RTK correction loss aRTK is established. The receiver
uses Atlas corrections in the absence of RTK. This allows for a slower

Mounting Options

Overview

There are two options for mounting the H328:

• Indirect Electrical Connection (cable) method

connection

board and then mount the H328 on the standoffs and RF and header
connectors. This method is very cost effective as it does not use cable
assemblies to interface the H328.

Note: Be aware of the GPS RF signals present on the carrier board and
ensure the correct standoff height to avoid any stress on the board when
fastening.

The H328 uses a standoff height of 7.0 mm (0.2756 in). With this height,
there should be no washers between either the standoff and the H328, or
the standoff and the carrier board. You may need to change the standoff
height if you select a different header connector.

If you want to use a right angle MMCX connector, use a taller header
connector 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 for H328 connector information.

The mounting holes of the H328 have a standard inner diameter of 3.50 mm

in the cable system. Essentially, there is a maximum cable loss budget of 30
dB for a 40dB gain antenna. Depending on the chosen antenna, the loss
budget will likely be lower (a 24dB 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

To enable Ethernet, determine if the receiver is allowed to be assigned an IP
address automatically via DHCP, or statically assigned. If you are unsure,
please contact the administrator of the network you wish to connect it to.

To enable Ethernet support with a DHCP-assigned IP address, simply use the
command:
$JETHERNET,MODE,DHCP

The receiver will attempt to get an address from the DHCP server on the
network. You should be able to see the current IP address reported by a
“$JETHERNET” query change.

To enable Ethernet support with a statically assigned IP address, use the
command:
$JETHERNET,MODE,STATIC,ip,subnet,gateway,dns

In the previous command, ip/subnet/gateway/dns are each replaced with
the relevant IP address. The gateway and dns parameters are optional, and
only useful for allowing outgoing connections from the H328 (not currently
supported) . The following is an example command:

Ethernet by default, so to make practical use of Ethernet support, enable a
service.

The only Ethernet service implemented is the PORTI virtual serial port.
Additional types of Ethernet services may be implemented in future
firmware versions.

The PORTI virtual serial port allows a listening TCP port to be opened, acting
like a local serial port of the receiver. Only one TCP client may be connected
at a time.

Note: Enabling “PORTI” on Ethernet should only be done with the H328
connected to a trusted network, since it gives full access to the receiver as a
local serial port, and has no authentication or security mechanisms.

To enable the PORTI service, use the command $JETHERNET,PORTI, port
where port is replaced with the desired TCP port number. Any port in the
range 1 to 65535 is allowable, but it is recommended to consider which TCP
port numbers are typically reserved for various common protocols and avoid
those port numbers. To disable the PORTI service, use the command

Timing Signal

1PPS timing

The one pulse per second (1 PPS) timing signal is used in applications where

signal

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 high with rising edge synchronization.

The 1 PPS signal is capable of driving a load impedance greater than 10 kΩ in

parallel with 10 pF. The pulse is approximately 1 ms. The pulse width can be
adjusted by 100 ns.

The H328 supports a programmable PPS. Users can select the frequency to
1,2,5 or 10Hz. The H328 can support widths up to 900ms.

The width command parameter is in µs (microseconds).

$JPPS,RATE,<Rate_In_Hz (limited to 1.0 ,2.0 ,5.0 ,10.0 >,[SAVE]

or if you prefer to work with the period (inverse of RATE)

$JPPS,PERIOD,<Period in seconds (limited to 1.0, 0.5, 0.2, 0.1)

PPS Width can be controlled using

$JPPS,WIDTH,<width in µs (microseconds)>,[SAVE]

Note: $JSAVE does NOT save the JPPS configuration so the desired 1PPS

configuration settings must be applied every time the receiver is powered
on. Each parameter must be individually saved as it is entered (by adding the
optional SAVE at the end of the command).

application.

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 kΩ

and 10 pF respectively, with a threshold of lower than 0.7 V required to

the H328. These are not separate analog and digital grounds which require
separate attention. Refer to Table 2-1 through Table 2-2 for H328 pin-out

Speed Radar Pulse - 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 (3.28ft./s).

Note: Speed radar output is not essential to normal receiver operation. Do
not connect these pins if you do not need this function.

Note: This pin has no form of isolation or surge protection if using the Speed
Radar Pulse output. Hemisphere GNSS strongly recommends incorporating
some form of isolation circuitry into the supporting hardware.

Contact Hemisphere GNSS Customer Support for an example of an optically
isolated circuit.

H328 requires shielding from other electronics to ensure optimal operation.

The H328 shield design consists of a thin piece of metal with specific
diameter holes, preventing harmful interference from penetrating, while still

orientation of the antennas.

Heading is calculated from the vector created between the primary and
secondary antenna.

A heading, pitch, or roll bias may need to be set after installing the antennas
so the heading, pitch, and roll are correctly calibrated. The primary antenna
is used for positioning and the primary and secondary antennas, working in

pitch, send $JATT,ROLL,NO, $JATT,NEGTILT,NO, and $JATT,HBIAS,0 to the
receiver to tell the receiver the antennas are calculating pitch instead of roll
($JATT,ROLL,NO) and that a heading bias is not necessary.

If the pitch is calculated from the secondary to the primary antenna, send
$JATT,ROLL,NO, $JATT,NEGTILT,YES, and $JATT,HBIAS,180 to the receiver to
tell the receiver the antennas are calculating pitch.

Pitch is calculated from the primary to the secondary antenna, but needs to
be calculated from the secondary to the primary antenna. Swap the sign of
the angle with $JATT,NEGTILT,YES.

Heading is calculated from the primary to secondary antenna, it will be out

Roll orientation

If the angle calculated between the primary and secondary antenna is the

roll, send $JATT,ROLL,YES, $JATT,NEGTILT,NO, and $JATT,HBIAS,-90 to the
receiver. This tells the receiver the antennas are calculating roll instead of
pitch ($JATT,ROLL,NO).

When heading should be 0 degrees, the heading output will be 90 (since the
antennas are calculating roll). Therefore, set the heading bias to -90 with
$JATT,HBIAS,-90.

If the roll is calculated from the secondary to the primary antenna, send
$JATT,ROLL,YES, $JATT,NEGTILT,YES, and $JATT,HBIAS,90 to the receiver. This
tells the receiver the antennas are calculating roll.

Roll is calculated from the primary to the secondary antenna. Swap the sign
of the angle with $JATT,NEGTILT,YES.

Heading is also calculated from the primary to secondary antenna, it will
show as 270 degrees when it should be 0. Add a heading bias of 90 with
$JATT,HBIAS,90.

Note: Regardless of which mounting orientation you use, the H328 provides
the ability to output the heave of the machine via the $GPHEV message. For
more information on this message refer to the Hemisphere GNSS Technical

Reference Manual.

Place the antennas:

• With a clear view of the horizon

• Away from other electronics and antennas

• Along the vessel’s centerline

You must install the primary antenna along the vessel’s centerline; you
cannot adjust the position readings if the primary antenna is installed off the
centerline. Positions are computed for the primary antenna.

Install on a level plane with a 20.0 m* maximum separation (default of 1.0 m)
away from radio frequencies as high as possible. For optimal performance,
orient the antennas so the antennas’ connectors face the same direction.

Note: *A multi-frequency activation is necessary if using a baseline greater
than 5m.

does not exceed the maximum operating temperature for the H328.

To achieve maximum dissipation, metal standoffs must be used on all six
mounting points of the H328. Users should implement preferred industry
standards for heat management.

Note: Thermal design may only be a concern if the integrated product’s
maximum design temperature is expected to be close to the temperature of
the H328.

values

J1000 and J2000 are for the primary and secondary
antennas.

• Heading is from primary to secondary antenna, so the

secondary antenna should be toward the bow and
primary toward the stern.

• Check the measurement of the antenna separation.

• The Measured (MSEP) and Calculated (CSEP) values are in

meters and should agree to within 1 cm. CSEP
continuously changes, so average this reading over
several minutes to obtain an approximate value.

• Check CSEP value is fairly constant without varying more

than 1 cm. Larger variations may indicate a high
multipath environment and require moving the antenna
locations.

• Reduce antenna separation - Hemisphere GNSS

recommends the separation between the antennas
remain below 5 m for accurate and timely heading
reading output

• $JATT,SEARCH command forces the H328 to acquire a

new heading solution. This should also be used after
entering a new MSEP value

• $JATT, GYROAID, YES Enable gyro aid as this will give

heading for up to 3 minutes in times of GNSS signal loss

• Enable tilt aid to reduce heading search times

• Check the applications receiver using the $JAPP query;

the receiver should answer $JAPP, MFAATT, 1,2

• Monitor the number of satellites and SNR values for both

antennas within SLXMON; at least 3 satellites should have
SNR values > 20

• Antenna connectors should both be facing the same

• Ensure the H328 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 H328 is connected to the
receive line of the other device. Also,
ensure the signal grounds are connected.

• If the H328 is connected to a custom or

special device, ensure the serial
connection to it does not have any
incompatible signal lines present which
prevent proper communication.

• Make sure the baud rate of the H328

matches the other device. The other
device must also support an 8-data bit, 1
stop bit, no parity port configuration (8-N-

serves to provide only an estimate of achievable accuracy based on specifications provided by
the US Department of Defense for GPS positioning and DGPS service provider performance
specifications, where applicable.

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.
