Problems solved by technology

The complexity and particularity of the space environment make it inevitable that satellites will be disturbed by external interference during orbital operation, and the satellite’s own components will inevitably fail during long-term operation. Due to the particularity of working conditions, fault detection, isolation, and recovery are all more indirect than ground systems. and difficulties

Embodiment Construction

[0068] The concrete implementation process of the inventive method is as figure 1 shown.

[0069] Here, the main components of a certain spacecraft (satellite) control system include primary and backup control computers, a set of 3+1S gyroscopes, 2 dual-axis digital sun sensors, 2 star sensors, and 4 pyramid configuration installations. Momentum wheels and chemical thrusters. When the satellite is in the normal ground-to-ground working mode, the star sensor and gyroscope combined filter attitude determination method is adopted on the star, and the gyroscope provides the three-axis attitude angular velocity. According to the present invention, the on-orbit stable operation capability of the spacecraft control system is constructed, and the main steps are as follows:

[0070] (1) Build data protection capabilities, that is, the ability of the system to maintain stable operation independently after the data required for the stable operation of the control system is affected by ...

Abstract

The invention relates to a spacecraft control system on-orbit stable operation capability construction method which can be used for control system ground development and on-orbit flight full life cycle, and the design method is widely applied to spacecrafts such as high, medium and low orbit satellites, airships, space stations and deep space detectors to improve the robustness of the spacecraft full life cycle. According to the spacecraft control system on-orbit stable operation capability construction method, six capabilities including the data protection capability, the data culling capability, the anomaly detection capability, the soft fault self-recovery capability, the hard fault self-reconstruction capability and the under-configuration operation capability are taken as supports. Inthe scheme design and the technical design of the control system, the attitude and the working mode of the spacecraft can be kept in a stable and continuous state according to the method.

Description

technical field [0001] The invention relates to a method for constructing the on-orbit stable operation capability of a spacecraft control system, which can be used for the development of the control system on the ground and the entire life cycle of the on-orbit flight. With the goal of improving the robustness of the entire life cycle of the spacecraft, it is proposed that data protection capabilities, data wilding capabilities, anomaly detection capabilities, soft fault self-recovery capabilities, hard fault self-reconfiguration capabilities, and under-configuration operation capabilities A total of "six capabilities" are the method for constructing the on-orbit stable operation capability of the spacecraft control system, which can be followed in the control system scheme design and technical design to maintain the attitude and working mode of the spacecraft in a stable and continuous state. Background technique [0002] The control system is the key subsystem of the spac...
