Application and Realization of Real-Time One Key Phase-Calibration for TT&C Antenna
In this paper the limitations of routine phase-calibration are analyzed, in order to solve the problems, we study the principle of quick phase-calibration, in the end, a method of real-time one key phase-calibration is designed and realized. Using this method the antenna doesn’t need the calibration tower, even the antenna needn’t point precisely to the target satellites, and the calibration process spends only within 10 seconds, so we can carry on real-time phase-calibration based on program tracking mode when it meets the requirements. Test has proved that the method can be used in LEOP (Launch Early Orbit Phase) missions, and then we can improve emergency response capabilities of tracking faults in LEOP missions.
