摘　　要：对SZ-GNSS CORS覆盖范围内的定位精度进行检测,可确定系统设计是否达标,使各类卫星定位作业模式的针对性更强,经济效益更高。本文对SZ-GNSS CORS的平面定位精度检测方法和检测精度进行分析,结果表明,在SZ-GNSS CORS中RTK观测模式下X和Y方向的内附合中误差为5mm左右,外附合中误差为11mm左右;动态规则几何轨迹的检测结果良好。平面定位精度达到设计要求,在很大程度上能够满足苏州城市建设和信息化建设对GNSS的需求。For SZ - GNSS CORS within range of the positioning accuracy of testing, to determine whether the system design, make all kinds of satellite positioning operation mode in a more targeted economic efficiency is higher. In this paper, the SZ - GNSS CORS plane positioning precision of the detection methods and detection precision were analyzed, and the results show that in SZ - GNSS RTK CORS in observation mode Xand Ydirection of enclosed in error is about 5 mm, outside along with the error about 11 mm; Dynamic rules of geometrical locus detection results is good. Plane positioning accuracy to meet the design requirements, to a great extent, can satisfy the suzhou city construction and information construction requirements of GNSS.
