ABSTRACT:
There is provided a telescope system including: a main reflector unit; a pedestal unit that bears the main reflector unit to be rotatable around AZ and EL axes; and a motor that drives the main reflector unit. The telescope system corrects deformation of the main reflector unit and the pedestal unit due to the wind force to improve pointing accuracy of the mina mirror unit and the pedestal unit. The telescope system detects motor torques on the AZ axis and the EL axis, predicts deformation of a telescope due to the wind force from torque signals of the motor torques and a pointing error due to the deformation and feeds back the deformation and the pointing error to AZ and EL command values to perform correction of the pointing error.
