the correction for dopplershift is done when a offset of hertz is reached, so no update every 500ms but, when the frequence drifted more then for example 40 Hz. This reduce heave load on the interface, when the satellite is far away.

This is a good idea, the same concept is already used in the rotator controller with a variable threshold.
