基于姿态和角速度匹配的惯性基准快速传递方法
Inertial Reference Rapid Transfer Based on Attitude and Angular Velocity Matching
摘要
Abstract
This paper studies the fusion of star sensors and gyroscopes measurement information on satellite platform to transfer the inertial reference from the platform to the payload,such that the attitude of the payload can be controlled independently and its space missions can be accomplished after the payload is released from the platform.The primary purpose of the inertial reference transfer is to establish a reference coordinate system in the payload.Generally,the calculation of the attitude transform matrix from the platform coordinate system to the inertial coordinate system is required.In addition,the main error parameters of the inertial measurement unit on the payload should be determined.In existing methods for inertial reference transfer,the attitude of the payload and the main error parameters of the inertial measurement unit on the payload are estimated based on the star sensors on the platform.However,the typical transfer alignment time is on the order of one hour.It is difficult to meet the requirement of the space missions in the case of emergency.In order to cope with this problem,an inertial reference transfer model based on the attitude and angular velocity matching is established.Furthermore,a platform attitude maneuver optimization method based on the Cramer-Raolower bound(CRLB)is presented to improve the rapidity of the inertial reference transfer.The angular velocity measurement information of the platform is introduced for inertial reference transfer.The platform attitude maneuver time is planned based on the CRLB of the inertial reference transfer system.Then Kalman filter(KF)is designed to estimate the attitude of the payload and the main error parameters of the gyroscopes in the payload.The effectiveness of the presented method is evaluated through numerical simulations.关键词
