Synchronous heave is available up to the rate of the IMU. It can also be logged 'on time' at lower rates.

This log also includes information about the estimated accuracy of the heave value through the standard deviation of the heave. This heave solution is calculated at the location entered in the SETINSTRANSLATION USER command.

You must have an inertial solution to use this log.

Refer also to information in the SETHEAVEWINDOW command.
