PROBLEM TO BE SOLVED: To improve estimation accuracy of satellite tracking.SOLUTION: A tracking control unit 5 acquires an orbit prediction value 4 of a satellite and an antenna actual angle 3 for tracking the satellite, determines a time deviation between the orbit prediction value 4 and the antenna actual angle 3 at a scheduled time, and determines an off-set time for correcting the time deviation by a second order approximation. An antenna command value 6 is calculated by overlapping the off-set time with the orbit prediction value 4. An antenna drive unit 2 controls an attitude of an antenna 1 on the basis of the antenna command value calculated by the tracking control unit 5.SELECTED DRAWING: Figure 1 |
