摘要： An object of the present invention is to provide an antenna pointing control apparatus that reduces a pointing error of an antenna having a two-axis gimbal structure using a simple apparatus structure and a simple control. An antenna 200 installed on a ship hull is controlled so as to point toward a satellite by an antenna pointing control apparatus having a two-axis mechanism. Movement and rocking of the ship hull are recognized every prescribed cycle time, a satellite bearing is measured, and a pointing error of a directional antenna with respect to a satellite is detected. A determination is made as to whether or not the satellite will pass within a prescribed region A about an extension line of an AZ axis of the ship hull. If it is determined that the satellite will not pass within the prescribed region A, then a two-axis control of an EL axis and the AZ axis is executed. If it is determined that the satellite will pass within the prescribed region A, then a virtual three-axis control that assumes a virtual cross elevation axis exists and controls the EL axis and the AZ axis is executed.
