Antenna tracker barometer, can it update the Pixhawk copter barometer for drift?

Hi, can somebody please tell me if the Antenna tracker is updating the airborne vehicle FC barometer? I can’t tell if it is. I see in the AT Parameter List it has “GND_ALT_OFFSET: altitude offset” but don’t see a time/frequency update parameter. Be interested to know if this is a feature (updating the drift) in AT?
