Autonomous operation and control system of agile imaging satellite, and operation process of system

Abstract

The invention discloses an autonomous operation and control system of an agile imaging satellite. The autonomous operation and control system comprises a ground support system and an imaging satellite. The imaging satellite is equipped with a satellite housekeeping subsystem, an antenna subsystem, rest on-satellite subsystems, a satellite-borne replanning subsystem and a real-time task receiver. After the antenna subsystem receives a multi-source task message, the task requirement message is transmitted to the replanning subsystem, and the replanning subsystem generates a new task planning scheme, on the one hand, the new task planning scheme is transmitted to the antenna subsystem and sent back to a ground operation and control center, on the other hand, an instruction is generated and transmitted to the satellite housekeeping subsystem, and after the operation and control center receives the planning program from the satellite, the control instruction and the digital transmission scheme same with the satellite are synchronously generated, and sent to a measurement and control center and a ground station. The autonomous operation and control system can enhance the ability of the satellite to perform complex tasks; the actual observation efficiency of the tasks on the satellite can be effectively improved; the pressure of a measurement and control channel can be relieved, and the complexity of ground control is decreased; and a response can be effectively quickly made to emergencies.

Description

technical field [0001] The invention relates to an autonomous operation and control system of an agile imaging satellite and its operation flow. 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 ...

Problems solved by technology

With the enhancement of these capabilities, there are higher requirements for satellite application goals. Obviously, the traditional satellite ground control mode can hardly meet the satellite observation tasks with high timeliness and reliability requirements.
