VOID-IMU-CAL

The VOID-IMU-CAL command only applies to the baseline IMU and instructs the DVL to mark the IMU calibration coefficients as “invalid.” The DVL will then try to save the IMU calibration coefficients the next time the IMU reports a calibration status of “3333”. The difference between “GRAB” and “VOID” is, if the power is lost before a status of “3333” is achieved, with “GRAB” the old coefficients will remain available for the next time the system is powered up, and with “VOID” the calibration process will start from scratch.
