For example, the following commands can be used for enabling GPS, SBAS and Gal-
ileo at the same time but outputting GGA and RMC sentences every one second with
talker ID $GP at the header:
GPS:SYST:SEL GPS SBAS GAL
GPS:GPGGA 1
GPS:GPRMC 1
3.3.33 GPS:NMEA:SVN <GP | GN>
GPS-2700 with firmware revision 0.75 and later and uBlox 8 GNSS receiver adds sup-
port for switching the talker ID mode to GP for GSV command where only $GPGSV
(i.e., no $GLGSV, $GAGSV, or $GBGSV) string will be outputted for GPS, SBAS, and
QZSS.
This command allows the GPS-2700 to include all available satellite information for
GPS, SBAS, QZSS, Galileo, GLONASS, and BeiDou in $GPGSV string when the
talker ID mode is set to GP in
Section 3.3.32 “GPS:NMEA:TALK <GP | GN>” . The
default mode for this command is GP which excludes satellite information for GNSS
systems other than GPS, SBAS, and QZSS.
This command is effective only when the talker ID mode is GP meaning that GSV com-
mand will have GNSS-specific talker ID listed in Table 3.1 for each GNSS system
enabled if talker ID mode is GN.
This command has the following format:
GPS:NMEA:SVN <GP | GN>
If talker ID mode is GP, sending GPS:NMEA:SVN GN command will include all satel-
lites in view in multiple $GPGSV sentences for up to 24 satellites.
3.3.34 GPS:JAM?
Firmware revision 0.57 and later adds support for a GNSS signal jamming-indicator.
The GNSS receiver will detect, and flag jamming interference with levels ranging from
0 (no jamming) to 255 (strong jamming). Any level exceeding 50 will cause a
SYNC:HEALTH 0x800 event to be flagged, and the unit to disable the LOCK_OUT_OK
signal on connector J1.
3.3.35 GPS:FW?
This command returns the firmware version used inside the GNSS receiver itself.
3.3.36 GPS?
This query displays the selected GNSS systems and NMEA talker ID for GPS-2700
with firmware revision 0.75 and later and uBlox 8 receiver, configuration, position,
speed, height, and other relevant data of the GNSS receiver in one convenient location.
3.4 GYRO SUBSYSTEM
The following Gyro commands are supported:
GYRO:MODE <ON | OFF>
GYRO:TRA <int> [0,255]
GYRO:PORT <RS232 | USB>
GYRO:PORT?
GYRO:CAL <float,float,float,float,float,float>
GYRO:CAL:COMP
GYRO:CAL:RESET
