Study of Recursive Algorithm for The GPS Positioning Solution

摘要：

The traditional algorithms for absolute GPS positioning are analyzed in this paper. New methods for increasing the accuracy of the pseudorange and the speed of solutions are presented. They are using recursive emendatory Gram-Schmidt method or recursive Householder transformation to solve which based on QR-factorization. According to the theoretic analysis and simulation result, new algorithm is more accurate than the traditional, and can estimate the three-dimensional positional parameter and timing clock error parameter in GPS fast and real-timely.
