The calibration maintenance adjusting and maintain the satellite ground station. It’s an important link in the construction and operation. Calibration equipment can eliminate the system errors caused by ground station in use process, but the traditional fixed calibration tower can"t meet the far field conditions of Ka band. The calibration method, that using unmanned aerial vehicle (UAV) platform to replace fixed tower, can simultaneously meet the requirements of S/X/Ka band ground station. This method make the calibration equipment more agile and flexible, and less the construction cost. Through researching the UAV laws and regulations, and the important performance index demonstration system, it is designed UAV Test Calibration of S/X/Ka band Satellite Ground Station. By adopting Ⅱ kind of unmanned aerial vehicle (UAV) platform, it’s running with carrying a payload calibration source, antenna, remote control module. It’s controlled through the ground and airborne communications link signal such as on and off, switching polarization control. The practical applications meet the S/X/Ka band satellite ground station engineering applications.
