Abstract

The present application proposes a satellite attitude control system, comprising: a command processing module, an attitude determination module connected to the command processing module, an attitude control module and an information storage module, wherein the command processing module is used for receiving, interpreting, discriminating and executing Control instructions from the ground station or the star management system; the attitude determination module is used to calculate the current attitude information of the satellite according to the measurement data collected by the attitude sensitive device in the preset control stage, and the attitude control module obtains the attitude information determined by the attitude determination module. , and according to the attitude information, calculate according to the control law corresponding to the preset control stage, generate the control command of the attitude control actuator, and drive the attitude control actuator to execute the control command; the information storage module is used to store the information and attitude of the attitude sensitive device. The information of the actuator is controlled, and the stored information is composed of the whole orbit data package and transmitted to the ground station. The present application satisfies the attitude control requirements of satellites at various stages.

Description

technical field [0001] The invention relates to a satellite attitude control system (Attitude Determination and Control System, ADCS), belonging to the technical field of spacecraft attitude control. Background technique [0002] Satellite attitude control system is an important part of the whole satellite system. The attitude control system is an embedded real-time control system. It is different from the general control system, its composition is complex, and its reliability is high. The attitude control system specifically includes satellite body dynamics analysis, attitude sensors, attitude determination algorithms, attitude control algorithms, and actuators. [0003] The design goal of attitude control system software, like all software designs, is to meet the requirements to the maximum extent under the constraints of time and various resource environments. The on-orbit operating environment of the attitude control system is constantly changing. The software design ...
