At$Gpsflt Gps Speed Filter - Novatel MT 3050 At Command Reference

AT$GPSFLT GPS Speed Filter

AT$GPSFL- GPS Speed Filter
T
At times the GPS chipset used by this device will report non-zero speeds when the device is not
Command
Function moving. Normally, the positions are accurate but the false speeds cause errors in the generation of
the GPS idle, distance and odometer features. This filter is usually able to detect these false motions
and clamp the reported speed to 0.0 knots while still reporting valid position data.
Under normal circumstances, the default values should provide acceptable GPS performance for
most applications. Please contact Novatel Wireless customer support if you feel the filter settings
need to be changed for your application.
