<P>PROBLEM TO BE SOLVED: To provide an antenna device that carries out highly accurate correction of direction errors occurring in a direction of antenna directivity. Ž<P>SOLUTION: A position control for AZ/EL angle instruction value is carried out by feeding back outputs of a rate sensor 13 and angle detector 14 to a servo control circuit 10. Displacement of a plurality of frame structures disposed on an antenna mount is detected by a displacement gauge group 15, and the metrology correction amount is calculated by a metrology correction portion 16, based on the data group measured by the displacement gauge group 15 and angle data detected by an angel detector 14. This results in not only adding the metrology correction amount and a device error correction amount resulting from an error correction portion 17, but also correcting the AZ/EL angle instruction value.
