4.11.1 INTGPS:SATellite
This group of commands describe the satellite constellation as seen by the internal GNSS receiver.
4.11.2 INTGPS:SATellite:TRAcking:COUNt?
This query returns the number of satellites being tracked by the internal GNSS receiver.
4.11.3 INTGPS:SATellite:VISible:COUNt?
This query returns the number of satellites that the almanac predicts should be visible, given date,
time, and position.
4.11.4 Internal GNSS Receiver NMEA Support
The following commands allow the RSR GNSS Transcoder™ to provide standard NMEA data from
the internal GNSS receiver. The GPGGA,GPRMC, GPGSV, PASHR and GPZDA NMEA
commands comprise all necessary information about the antenna position, height, velocity, direction,
satellite info, fix info, time, date and other information that can be used by standard navigation
applications or as a comparison with the simulation results from the target GPS receiver.
Once enabled, the RSR GNSS Transcoder™ will send out information on the USB serial interface
automatically every N seconds. All incoming serial commands are still recognized by RSR GNSS
Transcoder™ since the serial interface transmit and receive lines are completely independent of one
another. Please note that the NMEA output configured for the internal GNSS receiver appears
identical to the NMEA output for the optional external GNSS receiver. To prevent confusing the
output, only one (internal or external) NMEA sentence of each type should be enabled.
Please also note that the position, direction, and speed data is delayed by one second from when the
GPS receiver internally reported these to the RSR GNSS Transcoder™’s Microprocessor, so the
position is valid for the 1PPS pulse previous to the last 1PPS pulse at the time the data is sent (one
second delay). The time and date are properly output with correct UTC synchronization to the 1PPS
pulse immediately prior to the data being sent.
Once set, the following two commands will be stored in NV memory, and generate output
information even after power to the unit has been cycled.
