In view of the low reuse rate of the telemetry after-process software and the poor usability of independent version of each model, the generalized idea is used to design the telemetry data processing software that supports multiple models. The database model is established by studying the frame format of the telemetry ground receiving station, and the main functional modules of the universal telemetry data processing platform are realized by the object-oriented method, and the special problems in which the digital quantity appears in the sub-frame and the periods are different at different stages are carried out. The results show that the software can improve the reliability of the telemetry data processing and the efficiency of fault analysis, and point out the direction for the subsequent product engineering construction.
