一种北斗伪距单点定位的整体最小二乘(TLS)算法
首发时间:2015-09-14
摘要:目前,北斗伪距单点定位一般都采用普通最小二乘定位算法,但是,该算法只是考虑了观测方程的常数项的误差,而实际上观测方程的系数矩阵也存在误差,针对这一现象,对北斗伪距单点定位采用整体最小二乘算法,把系数矩阵和常数项的误差都考虑进去,与普通最小二乘算法相比,定位精度更高,应用范围更广。

A pseudo-range singe point positioning algorithm for the Beidou navigation system based on total least squares
Abstract:At present,BDS pseudo-range single point positioning is generally used oridinary least squares,however,the algorithm is only considered the error of constant term,in fact,coefficient matrix of observation equation is also contained error,for this phenomenon,using total least squares algorithm for BDS pseudo-range single point positioning,the error of the coefficient matrix and the constant term is considered,compared with ordinary least squares algorithm,higher accuracy and wider application.????
Keywords: GNSS single point positioning Least Squares Algorithm?????
