Satellite entry-exit independent telemetry processing control method

Abstract

A satellite entry-exit independent telemetry processing control method sets a time mark instruction group for each satellite mission. Each time mark instruction group is composed of time mark instructions with time marks, and the execution time of the time mark instructions is the time indicated by corresponding time marks. A program control cycle is set according to a satellite orbit cycle, timemark instruction groups required by one program control cycle are injected on the ground in one time, a satellite retrieves corresponding time mark instruction groups according to the current executing mission, then corresponding instructions in the time mark instruction groups are executed according to the current satellite time, and all the time mark instructions are executed sequentially according to the time marks. After one instruction is completed, the instruction is automatically arranged at the rears of the time mark instruction groups, and one program control cycle is added on an original execution time so as to serve as the next execution time. If overtime occurs in the time mark instruction execution process, the instruction is executed at once or given up. The method can achieve satellite entry-exit independent telemetry management.

Description

technical field [0001] The invention belongs to the technical field of spacecraft measurement, control and communication, and relates to a satellite autonomous telemetry control method. Background technique [0002] The telemetry data of the spacecraft generally includes the health data, working condition data, remote control response data and performance data of each subsystem and each equipment. Telemetry data is of great significance for understanding the health status and working status of the spacecraft. However, due to the limitation of the number and distribution of measurement and control points, the spacecraft has an unmonitorable arc section, which becomes a blind area for spacecraft monitoring. How to obtain the telemetry information of this working segment has become an important issue. [0003] The traditional method is that before the satellite enters the invisible arc (ie exit), the ground injection command gives the storage strategy for the telemetry in the...
