摘 要：The precision assessment of the telemetry、track and command （TT＆C）equipment are important to ensure they can work normally. A new method is proposed for precision assessment of the space TT＆C equipment in this paper. In this method, anUnmanned Aerial Vehicle （UAV）equipedwith global positioning system （GPS） receiver acts as the target, well the positioning information of target is obtained by DGPS technology and the Kalman Filtering is used to reduce the effects of disturbance to enhance the positioning accuracy. The precisionof the space TT＆C equipment is obtained through thecomparison of the positioning data by DGPS and the observation by the space TT＆Col equipment. The UAV flightadjusting system is built based on this method in this paper, and the result of flying experiment shows that this system can provide the high-precision standard data, which have many advantages such as strong mobility and wide application scope. This system provides a new efficient solution for precision assessment of space TT＆C equipment, which lays the foundation for the application of BeiDou in the precision assessment field.
