3.2.3 HELP?
This query returns a list of the commands available for the Mini-JLT GNSS™ GPSDO.
3.3 GPS Subsystem
Note: Please note that Mini-JLT GNSS™ displays antenna height in MSL Meters rather than in GPS
Meters on all commands that return antenna height [the legacy Fury GPSDO uses GPS height]. The
NMEA position fixes are in the WGS84 coordinate system, while the X,Y, and Z velocity vectors are
given in the ECEF coordinate system.
The GPS subsystem regroups all the commands related to the control and status of the GNSS
receiver. The list of the commands supported is the following:
