Design of real-time simulation model based on synchronous telemetry signal processing

Satellite telemetry signal resolution is an important part of satellite integrated test system. The traditional telemetry signal acquisition scheme is based on the Windows non real-time platform, which reduces the real-time resolution and the effectiveness of the interpretation.The design idea, principle and function realization of the telemetry signal simulation model based on real time system model architecture are expounded from the point of view of the application scene of the model system of the fault plan. This method inherits the iterative characteristics of the model, and obtains the telemetry information in real time by comparing the reading of the special flow data and the recognition of the synchronous frame head in each cycle. It provides sufficient information for the design of the fault plan, and has a strong practical significance.
