Incremental model-based spacecraft telemetering method

Abstract

The invention discloses an incremental model-based spacecraft telemetering method. The method comprises the steps of (1) building a spacecraft incremental telemetering design model which includes a data system model, a detail design model and a system integration model; (2) finishing related parameter design of the data system model, the detail design model and the system integration model in sequence; (3) converting the data system model, the detail design model and the system integration model after parameter design into configuration codes compilable for a computer; (4) finishing configuration code combination and providing the configuration codes for satellite-borne telemetering software components; and (5) reading the corresponding configuration codes by satellite-borne software, and finishing spacecraft telemetering data acquisition, storage, retrieval, packing, scheduling, framing, virtual channel scheduling and telemetering transmission frame generation and transmission. The method can ensure design information of a spacecraft telemetering system not to be repeated and omitted, thereby remarkably improving the design efficiency of the spacecraft telemetering system.

Description

technical field [0001] The invention belongs to the field of space vehicle measurement and control, relates to a space vehicle telemetry method, and is suitable for the space vehicle telemetry system design. Background technique [0002] The spacecraft telemetry system is an important functional part of the spacecraft, including functions such as telemetry data collection, storage, organization, scheduling, and downloading. The telemetry system plays an important role in the spacecraft field, covering the entire process of spacecraft system functional testing and on-orbit application. Therefore, a high-efficiency, zero-error telemetry system design method is a necessary prerequisite to ensure the safety and reliability of spacecraft system testing and on-orbit operation. [0003] "Small Satellite Software Telemetry Scheme and Modular Design Method" (Journal of Quantum Electronics, Vol. 21, No. 3, 2004) proposed a telemetry system design method based on modular design.

Problems solved by technology

There are tens of thousands of telemetry parameters for large and complex spacecraft. In the process of model development, when manually writing software codes related to telemetry parameters, the workload of program writing, testing and verification is enormous.

Due to the lack of a telemetry design model compatible with the design of spaceborne telemetry software components, models in different fields provide different levels of refinement, methods, and formats for telemetry system design inputs,
