Design for Automatic Generation of Spacecraft Telemetry Software Code Based on Incremental Model

This paper describes an automatic generation method of spacecraft telemetry software code based on incremental model. First of all, a spacecraft incremental telemetry design model is established, including data system architecture model, detailed design model and system integration model. Secondly, the related parameter design of each telemetry design model is completed in turn. Then, each telemetry design model is automatically transformed to software configuration code of onboard computer, which is compilable. Combination of the configuration code is used for the construction of the data pool based satellite telemetry software. Finally, the onboard software completes the telemetry data acquisition, storage, retrieval, grouping, scheduling, framing, virtual channel scheduling, the generation and transmission of telemetry frame by reading the corresponding configuration code.
