S/X/Ka频段卫星地面站无人机测试标校设计

利用测试标校设备对卫星地面站系统进行校准维护,是卫星地面站建设和运行过程中的重要环节;标校设备能够消除地面站在使用过程中产生的系统误差,但是传统固定标校塔不能满足Ka频段的远场使用条件,因此采用无人机平台取代固定标校塔能够同时满足S/X/Ka三频段地面站使用需求,提高了标校设备使用的机动性和灵活性,降低了建设成本;通过对无人机使用的法律法规研究,对系统重要性能指标论证,设计了三频段测控数传一体地面站无人机测试标校系统,采用Ⅱ类无人机平台,搭载有效载荷标校源、天线、远控模块,通过地面与机载通信链路进行信号通断、极化切换等控制,经实际应用满足了S/X/Ka频段卫星地面站建设工程上的应用。

S/X/Ka Band Satellite Ground Station UAV Test Calibration Design

The calibration equipments adjust 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 adoptingⅡkind 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.
