Embodiment Construction

[0013] The main difference between the autonomous operation and control system of the present invention and the traditional operation and control system is that the satellite load planning subsystem and the Beidou terminal are equipped on the imaging satellite. The re-planning subsystem mainly realizes the online task planning function of all observation tasks in the system. It can not only plan the tasks in the current task planning period according to the constraints and resource conditions at one time, but also combine the original task planning scheme to plan new arrivals. Re-planning of emergency tasks to meet the real-time requirements of emergency dispatching; Beidou terminals belong to the antenna subsystem and are used for real-time short message information interaction between satellites and users, satellites and ground support systems, that is, users can use different terminals, Use the Beidou short message to send mission demand information to the satellite, and the...

Abstract

The invention discloses an autonomous control system for an agile imaging satellite. The imaging satellite is provided with a satellite-borne replanning sub-system and a real-time task receiver; the real-time task receiver is used for carrying out real-time short message information interaction between the imaging satellite and users and between the imaging satellite and a ground supporting system; the replanning sub-system comprises a task preprocessing module, a test replanning module and a command generating module; the task preprocessing module is used for decomposing a target into a plurality of meta tasks and converting the target indication information of each meta task into target guide information; the task replanning module is used for receiving a preprocessing result and generating a new task planning scheme; and the command generating module is used for generating a satellite command from the generated task planning scheme and transmitting the satellite command to a satellite task sub-system for execution. According to the autonomous control system disclosed by the invention, the task planning scheme can be autonomously and partially adjusted according to the decided satellite task planning scheme and task requirements received in real time, so that in-time response to real-time tasks is realized, and the actual observation efficiency is improved.

Description

technical field [0001] The invention relates to an autonomous operation and control system of an agile imaging satellite. Background technique [0002] If an imaging satellite wants to efficiently realize the earth observation task, it needs the joint completion of the operation and control center, the measurement and control center, the ground station and the satellite in orbit. It is usually customary to collectively refer to the operation and control center, measurement and control center, and ground station as the ground support system. An imaging satellite itself constitutes an on-board system, which generally includes a star service subsystem, an antenna subsystem, an attitude control subsystem, and an imaging payload subsystem. system, data storage subsystem, power supply subsystem and temperature control subsystem, etc. [0003] The current observation task planning is usually carried out on the ground, and the planning period varies from one day to several days. Af...
