11. Continuous self-monitoring of the INS health
The Inertial Labs INS has continuous built-in monitoring of the INS health. In
the main mode the INS sends out Unit Status Word (USW) in each data
block (see also Appendix C).
The low byte (bits 0-7) of USW indicates failure of the INS. If this byte is 0
then the INS operates correctly, if it is not 0, see “Appendix D. The Unit
Status Word definition” for type of failure or contact the developers directly.
The high byte (bits 8-15) contains a warning or is informative for the user.
Status of each bit of the USW warning byte is specified in the “Appendix D.
The Unit Status Word definition”.
Since INS GUI version 2.0.29.110 from 09/02/2016 the GUI software stops
the INS unit if failure of gyro or accelerometer is detected. After the INS unit
is stopped error message with a caption about failure appears.
