RSR GNSS Transcoder™ User Manual
4.10.7 GPS:GPRMC
This command instructs the RSR GNSS Transcoder to send the NMEA standard string $GPRMC
every N seconds, with N in the interval [0,255]. The command is disabled during the initial warm-up
phase.
This command has the following format:
GPS:GPRMC <int> [0,255]
4.10.8 GPS:GPZDA
This command instructs the RSR GNSS Transcoder to send the NMEA standard string $GPZDA
every N seconds, with N in the interval [0,255]. The command is disabled during the initial warm-up
phase.
This command has the following format:
GPS:GPZDA <int> [0,255]
4.10.9 GPS:GPGSV
This command instructs the RSR GNSS Transcoder to send the NMEA standard string $GPGSV
every N seconds, with N in the interval [0,255]. The command is disabled until the GNSS receiver
achieves a first fix.
GPS:GPGSV <int> [0,255]
Please note that due to the large number of GNSS satellites that can be tracked in this unit, more than
the customary four GSV messages can be sent once per second. With multiple GNSS systems
enabled, a typical sky view may generate up to six GSV messages per second.
To simultaneously support all available GNSS systems, the following PRN numbering scheme
modified from the traditional NMEA standard is being used:
GNSS Type SV Range GPGSV PRN vehicle

SBAS S120-S158 33-64,152-158
