The Inner Orbit Linked Antenna Pointing Control Algorithm for Tracking and Data Relay Satellite Tracking Aircraft

Aiming at the tracking and data relay satellite(TDRS) tracking target of the aircraft,the inner orbit linked antenna(IOLA) pointing control algorithm for TDRS tracking the aircraft was studied.Considering the characteristics of TDRS acquisition and tracking system and the flight of the aircraft,the pointing control algorithm of IOLA tracking the aircraft based on the prearranged path was completed.The high precise pointing movement of IOLA was executed with the control strategy using the multisection fit method and least square method with restrictions.The example of tracking control calculation was done and the control algorithm showed its high precision.
