| 摘 要： | 针对单系统RTK存在可见卫星数少等问题,文中研究BDS/GPS站间单差的RTK算法模型,该模型采用二次型函数部分最小化及LAMBDA方法联合搜索模糊度。利用该模型分析BDS/GPS组合RTK的定位性能,通过短基线实测数据分析表明:站间单差RTK模型与双差模型是等价的;BDS/GPS组合系统相比于单一系统,明显提高定位的稳健性和精度,改善模糊度固定的成功率。

| Abstract: | As to single‐system RTK ,the number of visible satellites is small .This paper studies the across‐receiver of RTK algorithm model ,which uses combined partial minimization of quadratic functions with LAMBDA method to search ambiguity .The model analyzes the positioning performance of RTK combined with BDS/GPS . The short baseline measurement data analysis shows that :the cross‐receiver of RTK model is equivalent to double‐difference model .Compared to a single system , the combined BDS/GPS system can significantly improve the positioning accuracy and robustness ,and improve the success rate of ambiguity fixing . |
