标校卫星地面应用系统方案设计

卫星标校技术采用低轨卫星搭载标校载荷为地面测控设备标定系统误差，由于国内标校卫星发展较晚，相关研究主要集中于地面具体型号测控设备的卫星标校方法，缺少标校卫星地面系统研究以及真实卫星数据和试验验证手段。针对国内首个标校卫星型号“天平”一号卫星地面应用系统，设计了系统工作模式，提出了标校卫星任务规划方法，并对精密定轨调度和标校数据处理业务流程进行了分析设计。标校卫星地面应用系统面向标校用户提供测控设备标校服务，并为后续研究提供真实卫星数据和试验验证平台。

Scheme design of a calibration satellite ground application system

Satellite calibration technique employs low Earth orbit(LEO) satellite carrying calibration load to calibrate the systematic error of ground telemetry,tracking and command(TT&C) equipment.Due to the late development of domestic calibration satellite,the corresponding researches concentrate on the calibration methods of the ground TT&C equipment,and the researches on ground application system,real satellite data and the ways of experiment are lack.For the ground application system of China''s first calibration satellite TP-1,the work mode is designed,and the method of task planning is presented.Besides,the scheduling of the precise orbit determination and the calibration data process are designed.The proposed calibration satellite ground application system provides calibration service to the users,and also provides the real satellite data and an experiment platform for the future research.
