基准站变化对基于CORS系统的RTK数据质量影响

利用浙江省连续运行参考站系统(CORS)获取部分诸暨市实时动态(RTK)测量数据,选取其中12个测试点,比较基准站位置变化引起的CORS系统误差对RTK数据质量的影响,实验结果表明由于基准站变化导致CORS系统的RTK测量数据的高程误差不超过7 cm,平面误差不超过3 cm,满足浙江省GPS-RTK测量技术要求.

RTK Data Quality Study for Base Station Change of the CORS

Real Time Kinematic(RTK)measurements in Zhuji of Zhejiang Province were performed using Zhejiang Continuously Operating Reference Stations(ZJCORS).Twelve points were selected to test the errors caused by the change of CORS base station.The experimental shows that the position change of the base station of RTK in the CORS can lead to stronger elevation errors which are about 7cm,and smaller planar errors which are less than 3cm.With the change of base station,the achieved accuracy meets the requirements of Zhejiang GPS-RTK planar technical measurements.
