摘　　要：单基站CORS相对于多基站CORS具有成本低、建设时间短等优点。本文对北斗系统单基站RTD/RTK定位模型进行分析研究,并通过对实测数据对算法进行分析验证,RTD定位在东方向精度可以达到0.3 m,北方向精度可以达到0.4 m,高程精度可以达到0.8 m。RTK定位在平面精度可以达到1 cm,高程精度可以达到3 cm,可以满足不同类型的导航定位需求。Compared with multi-base CORS,single-base CORS has the advantages of low cost and fast construction time.This paper analyzes and researches the single-base RTD/RTK positioning model of Beidou system,and verifies the algorithm through the measured data.RTD positioning is in the East The directional accuracy can reach 0.3 m,the north direction accuracy can reach 0.4 m,and the elevation accuracy can reach 0.8 m.The accuracy of RTK positioning in the plane can reach 1 cm,and the elevation accuracy can reach 3 cm,which can meet the needs of different types of navigation and positioning.
