RSR GNSS Transcoder™ User Manual
This command instructs the RSR GNSS Transcoder™ to send the NMEA standard string $PASHR
every N seconds, with N in the interval [0,255]. The command is disabled until the internal GNSS
receiver achieves a first fix.
This command has the following format:
INTGPS:PASHR <int> [0,255]
4.11.11 INTGPS:HEIGHT:MSL?
This query returns the Mean Sea Level height in meters which differs from the GPS ellipsoid height
by up to +/-100 meters. This difference varies depending upon the location as reported by the internal
GPS receiver. Please note that the simulation uses GPS height in commands such as the
SIM:POS:LLH command described in Section
4.3.9
4.11.12 INTGPS:HEIGHT:GPS?
This query returns the GPS ellipsoid height in meters as reported by the internal GPS reference
receiver. It is calculated from the internal uBlox GNSS receivers’ MSL height parameter by
subtracting the MSL to GPS elipsoid height difference for the simulated position. This GPS height
should reflect the simulated height as set in the simulation commands such as the SIM:POS:LLH
command described in Section
4.3.9 .
4.11.13 INTGPS:HEIGHT?
This command returns the output from the following queries:
INTGPS:HEIGHT:MSL?
INTGPS:HEIGHT:GPS?
4.11.14 INTGPS:DYNAMic:MODE
This command allows the user to select the dynamic motion model being applied to the Kalmann
filters in the internal monitoring GNSS receiver. This allows for larger amounts of filtering for lower
velocity applications, effectively reducing noise and multipath interference. Applications with high
acceleration can now be used with fast filter settings to allow for the most accurate GPS coordinates
to be provided in high-dynamic applications such as Jet aircraft. Doppler tracking is enabled in all
airborne modes, as Carrier Phase tracking is very difficult to achieve in high velocity applications.
The GNSS receiver will perform Carrier Phase tracking for non-airborne modes.
The command has the following syntax:
INTGPS:DYNAMic:MODE <int> [0,8]
Sending the following command to the RSR GNSS Transcoder™ will select a stationary GNSS
dynamic model for example:
INTGPS:DYNAM:MODE 1
