The main contents of this dissertation consist of the following parts : an improved unscented kalman filter using spherical simplex unscented transformation ( sukf ) is derived in an attempt to solve the attitude estimation problem with the biased gyro or not from the vector observations 主要完成了以下幾方面的工作:針對有陀螺和無陀螺兩種模式,提出了一種基于簡化球形分布sigma點ut變換的改進型ukf濾波(sukf)的衛(wèi)星姿態(tài)估計算法。
In this dissertation, the nonlinear filter methods are deeply studied on theory and application for the attitude estimation from vector observations of the three-axis stabilized satellite attitude measurement system . furthermore, for the shortages in extended kalman filter, several improved schemes are presented 本文針對基于矢量觀測的三軸穩(wěn)定對地定向衛(wèi)星的姿態(tài)確定問題,從理論和應用兩個方面對衛(wèi)星姿態(tài)確定的非線性濾波技術作了深入和細致的研究。
