摘要
不同于双频数据的应用,多频数据的采用对单点定位有着特殊意义,可以更好地获得其模糊度的解。基于卫星导航定位系统多频载波相位线性组合理论,研究了具有特殊意义的组合观测值及其特性。在此基础上,通过多频观测值数据的数值仿真,采用新方法进行整周模糊度快速求解。编制了基于多频载波相位组合单点定位软件,通过结果的比较分析,得出有一定实际应用意义的结论。此方法算法简单,速度快,能够满足实时导航定位的需要,具有工程应用价值。
It is of special significance to position using multi-frequence carrier phase data other than two-frequency carrier phase data. In this way, the ambiguity resolution could easily be obstained. Based on the theory of the linear combination of multi-frequency carrier phase, this paper researched some special combination observations and their characteristics. With this new method, we simulated the multi-frequency observation data and got the rapid ambiguity resolution. We also wrote the software of point positioning based on the linear combination of multi-frequency carrier phase. From compared with and analysed the results, we got some conclusion which could be used in actual work. The algorithm was simple and it got results fast. This method can be used in engineering.
