Satellite acquisition control device and satellite acquisition control method

摘要

PROBLEM TO BE SOLVED: To provide a satellite acquisition control device which determines reliability of a measurement azimuth and reduces time required to acquire a communication satellite, and a satellite acquisition control method.SOLUTION: According to one embodiment, a satellite acquisition control device is the device of the satellite communication device performing communication via a communication satellite. Storage means stores first azimuth information being an azimuth at the time success of acquisition of the communication satellite in the past by using azimuth information. An azimuth sensor acquires second azimuth information being an azimuth of an antenna based on a position where the antenna is installed. Determination means compares the first azimuth information and the second azimuth information, and determines whether or not the second azimuth information acquired by the azimuth sensor is illegal. When the second azimuth information is determined not to be illegal by the determination means, acquisition control means performs a partial rough search with respect to a predetermined range including the azimuth indicated by the azimuth information, and when the second azimuth information is determined to be illegal, performs an omnidirectional rough search without performing the partial rough search.SELECTED DRAWING: Figure 2
