利用多频观测数据快速解算整周模糊度的算法研究

Research on Fast Integer Ambiguity Resolution Algorithm by Multi-frequency Observation Data

本文首先阐述了多频观测数据解算模糊度时所用到的矩阵转换的一些方法,讨论了由矩阵变换方法和CAR方法可以引申出的模糊度解算方法,指出TCAR/MCAR方法模糊度解算精度低的原因并改进,对短基线利用TCAR/MCAR方法进行模糊度解算,并与矩阵变换法做了比较。

This paper firstly gives some matrix changing methods for integer ambiguity resolution by multi-frequency observation data, and then concentrates on discussing matrix changing methods and ambiguity resolution methods detruded by CAR method,and point out the reason for poor precision to use TCAR/MCAR method on integer ambiguity resolution, and improve it, then ambiguity resolution is done by TCAR/MCAR method on short baseline, also compares with matrix changing method.
