Systems and methods are described for supporting dynamic antenna platform offset calibration for an antenna system mounted to a mobile vehicle. In particular, dynamic antenna platform offset calibration can be performed while communicating user data associated with the mobile vehicle (e.g., based at least in part on alignment calibration procedures including measurements of user data signals), with an antenna platform offset being updated when alignment calibration procedures have been performed at suitably separated spatial conditions. Accordingly, antenna platform offset calibration may be performed throughout the operation of the mobile vehicle without requiring that the vehicle be proactively aligned in a particular orientation for a dedicated calibration routine prior to using the antenna for communicating user data during normal operation of the mobile vehicle.
