基于载波相位技术的定向系统算法研究

Arithmetic Research of heading system based on carrier phase

本文以GPS差分载波相位技术和最小二乘模糊度搜索技术为基础,引入残差灵敏度矩阵和残差传递矩阵,减小模糊度的搜索空间,快速的解算出GPS载波相位整周模糊度,进而求得载体的姿态。并且将此算法进行软件设计,在PC机上实现数据的后处理,得到高精度的载体航向。

This paper that bases on GPS differential carrier phase technology and LSAST describes a method to reduce the ambiguity searcb space and obtain the GPS carrier phase integer ambiguity quickly through introducing Residual Sensitivity Matrix and Residual Transition Matrix. The arithmetic has been implemented PC program for data post processing and get high accuracy heading.
