1. A method of controlling an airborne antenna system for a radio telecommunications network mounted on an aircraft, the method comprising:
obtaining information indicating a current direction of the antenna system relative to geographic cardinal directions;
obtaining from a memory information indicating a predefined antenna direction relative to the geographic cardinal directions;
calculating an error using the information indicating the current direction and the information indicating the predefined antenna direction; and
stabilizing a physical antenna orientation of the antenna system in the predefined direction relative to the geographic cardinal directions, wherein
the stabilizing comprises controlling a rotational actuator of the antenna system based on the calculated error.
