Abstract

The present invention relates to a combined spacecraft data processing method based on layered routing, comprising the steps of: a. between each spacecraft cabin section and the ground through the three-layer identification of the spacecraft identifier, virtual channel, and data domain in the VCDU frame Realize the transmission of uplink injection data and downlink telemetry data of multiple spacecraft cabins through the space-ground link; b. Periodic interaction data between spacecraft cabins and spacecraft cabins and within each spacecraft cabin through the application in the EPDU package The progress identifier APID and the sub-leader realize the periodic interaction of data across cabins and subsystems; c. The sporadic interaction data between spacecraft cabins and spacecraft cabins and inside each spacecraft cabin is controlled by sub-package remote control The spacecraft identifier in the frame and the two-layer identification of the virtual channel realize interactive commands between different spacecraft in the combined spacecraft and different stand-alone devices on the spacecraft. According to the method of the invention, the standardization and autonomy of data processing on the device can be realized, and the system has good expansibility.

Description

technical field [0001] The invention relates to a combined spacecraft data processing method based on hierarchical routing. Background technique [0002] The information management system is an important part of the spacecraft. It is generally composed of a data management sub-system (or a satellite management sub-system) and a measurement and control data transmission sub-system. digital communication. [0003] At present, the existing spacecraft mainly use the traditional PCM format and AOS format for data framing and coding communication. In the spacecraft that fly independently or in short-term combination flight, due to the small scale of the system itself and the simple dynamic combination mode, the traditional design can already meet the needs of use. [0004] However, in a large-scale combined spacecraft, the traditional design is not versatile enough to support the dynamic access and exit of the data source of the visiting aircraft, to exchange data across spacecr...
