Aircraft-antenna controlling device, aircraft, aircraft-antenna selecting program, and aircraft-antenna controlling method
First Claim
1. An aircraft-antenna controlling device for an aircraft having multiple antennas for communicating with a wingman aircraft in flight, the multiple antennas being provided at different points on a fuselage, the aircraft-antenna controlling device comprising:
- a wingman-aircraft-position predicting part for predicting a predicted current position of the wingman aircraft based on a temporal change in position information indicating a position of the wingman aircraft in flight;
a selecting part for selecting, from among the multiple antennas, an antenna with which elongation with respect to a center axis of the respective antenna at the predicted current position of the wingman aircraft predicted by the wingman-aircraft-position predicting part falls within a coverage angle; and
a communication controlling means for executing communication with the wingman aircraft via the antenna selected by the selecting part,wherein, in a case where the predicted current position of the wingman aircraft falls within a respective coverage angle of more than one antenna from among the multiple antennas, the antenna from among the more than one antenna is further selected based on a difference between a center axis of the respective coverage angle and the elongation of each of the more than one antenna.

Abstract
A control unit of an aircraft includes a computer that predicts the current position of a wingman aircraft based on a temporal change in wingman-aircraft position information indicating the position of the wingman aircraft; an antenna selector that selects, from among multiple antennas, an antenna with which the elongation φt with respect to the center axis of the antenna at the predicted current position of the wingman aircraft predicted by the computer falls within a coverage angle θ; and a beam controller that executes communication with the wingman aircraft via the antenna selected by the antenna selector. Thus, the control unit of the aircraft can select an optimal antenna for communication with the wingman aircraft from among the multiple antennas.
