摘　　要：参考开源的RTKLIB代码,基于Visual Studio 2013设计开发了支持GPS、北斗卫星导航系统(BeiDou navigation satellite system, BDS)、GLONASS、GAILIEO数据的单频实时动态(real-time kinematic, RTK)解算软件MSRTK(multiple system RTK),并用实测数据对其进行了效果测试。结果表明,多模系统单频RTK解算技术是可行的,且四系统模式的定位精度要优于单系统、双系统和三系统模式的定位精度,即多模系统的引入可以提高单频RTK算法的定位精度。这一工作为多系统单频接收机的应用提供了参考。Based on Visual Studio 2013, a single frequency real-time kinematic(RTK) calculation software MSRTK(multiple system RTK)is designed and deve-loped by referring to the open source RTKLIB, which can support GPS, BDS(BeiDou navigation satellite system), GLONASS and GALILEO data. And measured data is used to test it. The results show that the single frequency RTK decoding technology of the multimode system is feasible, and the positioning accuracy of four-system mode is better than that of single-system mode, dual-system mode and three-system mode, confirming that the introduction of the multimode system can improve the positioning accuracy of the single frequency RTK algorithm. This research can provide reference for the application of multi-system single frequency receivers.
