在星上单机测试过程中，需要将星上数据通过CCSDS协议及其封装下传到地面PC机上，供其解析和分析。由于地面解析软件部分设计不合理，导致数据丢失或者实时性不强，造成测试人员误判，从而引起单机性能指标的误判。针对此类问题，基于MFC设计软件，提出基于串口驱动事件的方式，对星上遥测数据包进行丢包检测，同时对星上遥测数据包遥测量进行解析和判读。通过此软件，有效地检测到星上单机软件丢包现象的情况并简易地实现了星上遥测量状态的监测。

ln testing process of satel ite machine,the data of satel ite needs to be transferred to PC on the ground under the CCSDS protocol and its encapsulation for parsing and analysis.Due to design of ground analytic software is unreason-able,it leads to loss of data or real time capability not strong,which causes testers misjudgment and leads to miscalculation of a performance index.Aiming at this problem,based on the MFC design software and the way in which a serial port driv-er,the satel ite telemetry packet loss can be detected,while the satel ite telemetry data packet parsing and interpretation.
