| 摘 要： | GPS RTK定位技术,因其直观快捷、实时性强、点位误差不累积等优点在测绘生产中得到了普遍的使用,其误差由GPS的定位误差与坐标转换误差组成。文章结合该局将用GPS RTK技术在徐州新城区防洪工程进行控制测量,对利用该项技术测量的控制点相对于起始点的点位精度进行分析,并与传统导线测量的点位精度进行比较,以确保该次控制测量点的精度,并在以后的水利工程控制测量中加以应用。

| Abstract: | For the merits of intuitionistic and shortcut,strong real-time,none-accumulation end points error etc.GPS RTK poisoning technology is generally used,the difference is composed of poisoning error and coordinate transformation error.The Bureaue will use GPS RTK technology to carry out control surveying in flood-prevention project in new district of Xuzhou,the points accuracy relative to the start points by GPS RTK poisoning technology are analyzed,and compared with traditional wiremeasure methods in order to ensure the accuracy of these control points and the points are used in later hydro project control surveying. |
