摘　　要：网络RTK技术是一种高度集成的高精度定位技术。目前,基于GPS的网络RTK技术研究比较深入,已经趋近成熟,但基于北斗的网络RTK系统还不够完善。本文基于长江口北斗网络RTK试验平台的实测数据,对北斗和GPS的网络RTK线性内插算法精度进行了对比,实验证明线性内插算法同样适用于北斗网络RTK,能提供较高的精度。利用生成的虚拟参考站观测量与流动站进行事后解算,得到厘米级精度。说明基于北斗系统的网络RTK能够提供与GPS相当的精度结果。The network RTK technology is a highly integrated positioning technology with high precision. At present, the network RTK technology research based on the GPS is reaching maturity, but the BDS network RTK system is not perfect enough. This article is based on the actual measurements of the Yangtze Estuary BDS Network RTK Testing Plat- form. With comparing of the BDS and GPS network RTK accuracy based on linear interpola- tion algorithm, the experiment proves that the algorithm mentioned in this article works well for BDS network RTK with cm-level accuracy. The post processing experiments also obtain considerable accuracy.
