Mars capture process autonomous management method

Abstract

The invention discloses a Mars capture process autonomous management method which comprises a Mars detector rover Mars capture former management series, a Mars detector Mars capture process management series and a Mars detector Mars capture later management series which are used for managing an attitude control subsystem, a power supply subsystem, an integrated electronic subsystem and a measurement and control data transmission subsystem. Through the rational planning of detector management events before capture, in the capture and after the capture, through the multidisciplinary design optimization of energy, communication, attitude, lighting and the like, a completed capture process autonomous management series is established, and the autonomous management of the detector capture process is realized.

Description

technical field [0001] The invention relates to a self-management method of a spacecraft, in particular to a self-management method in the Mars capture process of a Mars probe. Background technique [0002] The capture stage is the most critical link in the entire ground fire transfer flight process, and the capture process determines the success or failure of the Mars exploration mission. The capture segment is defined as the flight process of the probe from entering the Mars influence sphere to the end of ignition braking. After 1990, in the Mars exploration missions that completed the escape from the earth, there were 5 failures, and the capture segment accounted for 4 times. The ground TT&C in the capture stage has a long time delay, high control accuracy and unique opportunities. It is difficult for the ground TT&C to meet the navigation accuracy and real-time requirements of the detector in the target capture stage, and the demand for autonomous control is the most ur...

AI Technical Summary

Problems solved by technology

In the capture stage, the ground measurement and control time delay is long, the control accuracy is high, and the opportunity is unique. It is difficult for the ground measurement and control to meet the navigation accuracy and real-time requirements of the detector in the target capture stage, and the demand for autonomous control is the most urgent.

However, there are many unknown factors in the space environment of the target acquisition segment, and the onboard resources are limited, which pose challenges to the adaptability, autonomy and fault tolerance of the detector navigation system.
