基于解析解的GPS伪距量测定位趋近算法

An approach algorithm of GPS pseudo range measurement positioning based on analytic solutions

用几何方法,给出了二维、三维测距定位问题解的解析表达式,在此解析解的基础上对GPS测码伪距定位问题提出一种趋近计算方法,并讨论了其收敛性,给出了其收敛的一个充分条件和解析求解中多解的裁决方法.

This paper gives analytic formulas for 2-D and 3-D positioning with range measurements by geometry method Based on these analytic solutions, an approach algorithm of pseudo range measurement positioning is put forward. Its convergence is discussed and a sufficient condition of its convergence and the method of deciding the final solution from multi-solutions are given.
