摘 要: 随着Galileo系统的逐步建成并投入使用,以及GPS的现代化,如何利用双系统多频率的组合观测值进行高精度定位已成为目前业内关注的热点问题。本文从传统的GPS双差观测方程出发,推导出了GPS-Galileo组合定位的数学模型,提出了其组合定位中的多频周跳探测方法和整周模糊度快速求解的方法。最后利用模拟软件对GPS、Galileo以及GPS-Galileo三种定位方式对不同长度基线的解算精度进行了比较分析,实验结果证明了所提方法的正确性和可行性。
关 键 词: 大地测量学;卫星导航;周跳探测;模糊度求解

Abstract: With the developing of Galileo and the modernizing of GPS, using GPS-Galileo multi-frequency combined observations to positioning has become a hotspot in the GNSS field. This thesis deduced out the mathematic model of GPS-Galileo combined positioning, based on the traditional GPS double differenced observation equations. We presented some new methods of cycle-slip detection and ambiguity resolution, by using of GPS-Galileo multi-frequency combined observations. Some different distance baselines were tested in the simulation experiments, respectively using GPS, Galileo and GPS-Galileo. And the precision of results were analyzed in detail. The results showed that present methods are right and feasible.
Key words: geodesy; satellite navigation; cycle-slip detection; ambiguity resolution
