The Recovery tab controls how the RT1003 will accept or reject GNSS measurements. The
GNSS control determines how many updates the RT1003 should ignore before forcing the
GNSS to be accepted. Both the velocity and the position can be controlled separately.
In the default state the RT1003 will reject up to 20 GNSS measurements before it forces the
GNSS to be accepted. However, in high multipath environments or when wheel speed
measurements are used, it may be desirable to reject more GNSS measurements. Select the
Start believing measurements after option and enter the number of GNSS measurements to
reject before the system starts believing it again.
The RT1003 GNSS receivers update both position and velocity at a rate of 5 Hz. Therefore,
to ignore updates for 60 seconds for example, the number to enter to start believing
measurements again would be 300.
The gx/ix processing algorithm makes its own decisions about when to trust and how to
recover from GNSS errors, so Use firmware defaults should be selected when using gx/ix
mode.
