Abstract
A technique for controlling an airborne antenna system (304) for a radio telecommunications network mounted on an aircraft (300) is described. As to a method aspect performed by the aircraft (300), a physical antenna orientation of the antenna system (304) relative to geographic cardinal directions is determined. The physical antenna orientation is stabilized in a predefined direction relative to the geographic cardinal directions by controlling a rotational actuator (514) of the antenna system (304).
Claims18
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.
A device of controlling an airborne antenna system for a radio telecommunications network mounted on an aircraft, comprising at least one processor and a memory, said memory comprising instructions executable by said at least one processor, wherein the device is configured to perform a 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.
