基于Partial-EIV模型的TLS姿态估计方法
TLS Attitude Estimate Method Based on Partial-EIV Model
摘要
Abstract
At first the observation equation based on multiplicative attitude error is deduced.Then based on the design matrix's feature of containing error,a new method of estimating attitude parameters via total least squares is introduced in this paper.In this problem,both random elements and stable elements exist in the design matrix in which there is a structural feature.Hence,Partial-EIV model is introduced and a new model conforming to the structural feature of the design matrix is developed.The new method is comPared with those existing methods via two simulated experiments.Finally,it is concluded that the precision of the total least squares method based on Partial-EIV model is higher than that of conventional least squares method,and its solution effect is almost the same as that of the multiplicative attitude error based least squares methods.Such results prove that the validity,rationality and applicability of the new method.关键词
