Operation
3. Make sure the base Sensor and the rover Sensor is connected.
4. Send the following command:
$PASHS,RTC,REM,B - to set the Sensor into RTCM remote mode, and
using port B to receive RTCM differential message.
5. Send the following command
$PASHS,CPD,MOD,ROV - to set the Sensor into CPD rover mode
6. To verify the setup, send $PASHQ,RTC and $PASHQ,CPD commands.
7. To save the above setup so it can be automatically recovered after power
loss, issue the command $PASHS,SAV.
8. The rover Sensor is now operational. Refer to “Monitoring Position” on
page 17 for more information on position information.
A typical GGA message with fixed ambiguities would be
$GPGGA,015454.00,3723.285136,N,12202.238517,W,3,08,01.0,+00012.
384,M,,M,00.123,0000
RTCM differential (pseudo-range) with type 1
message
Perform the following checklist prior to software setup.
1. The hardware setup is complete and correct.
2. All parameters are assumed to be at the factory default settings. Refer to
“Receiver Memory Reset” on page 16 on how to reset the parameters to the
factory defaults.
3. Check the options in the Sensor
• Base—‘D’ Differential option
• Rover—‘D’ Differential option or ‘U’ Differential Remote option
Refer to “Optional Features” on page 5 for information on how to verify
these options. Refer to Chapter 4, Command Response Formats for a
detailed explanation of the serial commands.
Base Setup
1. Power on the base Sensor.
2. Monitoring the satellite tracking and the autonomous position as described
in “Getting Started” on page 14.
3. Enter and verify the base coordinate as described in section Entering Base
Station Coordinates. Note the coordinates should be corrected for any
antenna phase center offsets, if applicable.
