Abstract
An antenna controller comprises an antenna beam control unit for controlling the direction of an antenna beam of an antenna, an inertial navigation system for acquiring motion information on a motion of the mobile body, an antenna beam direction calculation unit for calculating the direction of the antenna based on the motion information from the inertial navigation system to direct the antenna beam toward the geostationary satellite, a motion information acquisition unit for separately acquiring motion information on the motion of the mobile body, and a motion estimation unit for estimating a delay of the motion information acquired by the inertial navigation system based on the motion information acquired by the inertial navigation system and the motion information acquired by the motion information acquisition unit, and for estimating motion information to be sent to the antenna beam direction calculation unit in consideration of the estimated delay. The motion information acquisition unit has a 3-axis angular-velocity sensor. As an alternative, the motion information acquisition unit has a 3-axis magnetic bearing sensor.
