Menu-type design method based on optimized information integrated GEO satellite control system

Abstract

The invention provides a menu-type design method based on an optimized information integrated GEO satellite control system. The menu-type design method comprises the following steps: four pyramid-type long-life inertial posture sensor gyroscopes are configured on the long-life GEO satellite control system; sensors needed by various users are configured according to the hardware menu type design requirement; three types of Kalman filters are sequenced: three inertial posture sensor gyroscopes and an optical posture star sensor, three inertial posture sensor gyroscopes, an earth sensor and a sun sensor, and three inertial posture sensor gyroscopes and other type measurable triaxial posture sensors; when the detection of an FDIR module in a satellite computer application software is in failure, the FDIR module can automatically generate corresponding failure alarming, and the currently selected Kalman filters conduct automatic reduced order filtering, and when the failure is still not eliminated in the preset time, the automatic recombination can be realized through the FDIR module. According to the method, the cost performance, the carrier-to-interference ratio and the reliability of a satellite platform can be improved, and the development period can be obviously shortened.

Description

technical field [0001] The invention relates to an optimization-based information fusion GEO satellite control system menu design method, which belongs to the technical field of spacecraft control. Background technique [0002] The fixed-point launch cost of geostationary orbit (GEO) satellites is much higher than that of low- and medium-orbit satellites, so it is usually required to extend the working life. GEO satellites usually have a life span of more than 15 years now, and the on-board computer has high requirements for anti-radiation. To ensure reliability , the operating frequency of the computer is usually derated, which also reduces the computing power of the computer. In order to improve the accuracy of attitude determination and attitude control, it is necessary to reduce the sampling period of filtering and control. The computer is heavy, and the radiation-resistant high-performance chip has become a key component of the high-priced GEO satellite computer. [00...
