High-orbit remote sensing satellite load task execution performance method and system

Abstract

The invention discloses a high-orbit remote sensing satellite load task execution performance method and system. Through analysis of a load task instruction on a satellite, parameter calculation, configuration and scheduling performance of an equipment instruction are completed, the functions of multiple times of satellite maneuvering, load imaging and the like are completed through one-time injection of the load task instruction, and injection efficiency of the load task instruction is improved; through the scheme of performing verification during injection of the load task instruction, the reliability of performance of the load task instruction is improved; through the scheme of saving equipment instruction subsequences which are used repeatedly, performance efficiency of load task instruction configuration is improved; and through the scheme of storing the load task instruction which is not due and performing execution again after the load task instruction is due, storage space of the delayed load task instruction is saved.

Description

technical field [0001] The invention relates to a method and system for deploying and executing payload tasks of high-orbit remote sensing satellites, and relates to a method for deploying and executing payload tasks, in particular to a method for deploying and executing templated payload tasks of high-orbit remote sensing satellites when computer resources are limited. , belonging to the field of satellite mission execution. Background technique [0002] The main task of remote sensing satellites is to image the earth and complete the download of image data. A typical payload task includes the steps of data transmission subsystem equipment on / off setting, camera subsystem equipment on / off setting, satellite attitude maneuvering, camera imaging, image downloading or recording, etc. Each step needs to generate and send a series of control commands for related equipment. Different types of load tasks require different command combinations, and most of the commands configure d...

Problems solved by technology

However, this method of payload task processing will bring about two problems: First, due to the large number of payload mission remote control commands that need to be generated on the ground, especially in the case of continuous imaging or regional mobile imaging of high-orbit satellites, a single The task may be imaged and maneuvered hundreds of times, involving at least hundreds of instructions

[0006] (1) The method is mainly designed for a single imaging task of low-orbit satellites, and cannot be applied to high-orbit repeated imaging, regional splicing imaging and other working modes

High-orbit geosynchronous remote sensing satellites are relatively geostationary, and can periodically inspect the same location, or perform motorized imaging stitching on an area. Under these working conditions, a series of maneuvering and imaging actions need to be completed, and the method of using a directed graph is not applicable

[0007] (2) The method does not take into account the problem of equipment instruction verification and instruction data space occupation after expansion
