IMU data failure – FDIR2 failure detected

Problem

During GNSS inertial processing, a fatal error occurs and this message is added to the log file:

IMU data failure – FDIR2 failure detected.

Solution

This issue can be caused by many different reasons. Please attempt the following:

1. If GAMS was used, verify GAMS lever-arms or turn GAMS off.

2. If DMI was used, disabled DMI.

3. Change initialization mode in GNSS-inertial processor to VNAV.

4. In some cases, this can be caused by gaps in POS data. This has been fixed in TMI version 3.2.4. Please update the TMI version in case you are under maintenance.
