3.3.30 GPS:JAMlevel?
This command provides 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 and loss of the 1PPS signal from the GPS will cause a SYNC:HEALTH 0x800 event to
be flagged, and the unit to disable the LOCK_OK signal on connector J3.
3.3.31 GPS:FWver?
This command queries and returns the Firmware version used inside the GNSS receiver itself.
3.3.32 GPS?
This query displays the configuration, position, speed, height and other relevant data of the GNSS
receiver in one convenient location.
