摘　　要：针对基合导航系统的定位精度以及通信链路的稳定性问题,该文以基合导航系统和CORS为平台手段,在黑龙江省齐齐哈尔市建立单基站基合导航测试系统进行精度和稳定性测试研究。结果表明:基合导航系统静态和动态测试的定位精度达到了厘米级,具有较高的定位精度;用基合导航系统传输差分数据实现高精度实时动态定位的稳定性优于现有的移动通信技术。Terrestrial digital broadcasting technology and BeiDou satellite navigation technology were integrated, kinhood navigation system based on symbiotic FM data broadcast was borned.According to the problems of positioning accuracy and the stability of the communication link,we combined kinhood navigation system with CORS,and established a kinhood navigation system of single-reference station in Qiqihar city of Heilongjiang province for precision and stability test research.The results show that positioning accuracy of static and dynamic tests of kinhood navigation system has reached to centimeter level and has high positioning accuracy;Using CDRadio to transmit differential data for achieving high precision real-time dynamic positioning stability is superior to existed mobile communication technology.
