摘要(Abstract)：

针对我国地区观测数据的实验定位结果精度问题,该文提出BDS/GPS非差误差改正数的实时动态定位方法,研究了BDS/GPS单参考站非差实时动态定位算法模型,流动站使用非差误差改正数,不需要进行双差观测值的组合。参考站将非差误差改正数传递给流动站,对流动站的观测值进行误差改正,可以直接固定流动站的模糊度。实验表明:在我国南方地区BDS精度要优于GPS,而在北方地区,BDS/GPS定位精度和GPS定位精度明显优于BDS。并且与单系统相比,组合系统的可视卫星数明显增加,改善了卫星空间几何分布结构,从而提高了导航定位的可用性和精度。

关键词(KeyWords)： BDS/GPS组合系统;实时动态定位;精度分析;非差误差改正数
