千寻知寸FindCM在天津滨海新区的性能精度分析
|
摘要
简要介绍了千寻北斗地基增强系统及其主要产品。分别基于千寻知寸FindCM和BHCORS广域差分信号,在滨海新区的塘沽、天津港、汉沽、大港等地进行数据采集测试,重点分析其在WGS84大地坐标系下的实时定位内符合精度和外符合精度。结果表明:千寻知寸FindCM定位性能稳定可靠,在滨海新区具有实时动态厘米级精度,与BHCORS性能精度相当。
In this paper,Qianxun Beidou foundation reinforcement system and its main products were briefly introduced. Based on the wide area differential signals of FindCM and BHCORS,data acquisition tests were carried out in Tanggu,Tianjin Port,Hangu and Dagang of the Binhai New Area. The internal precision and external accuracy of real-time positioning in WGS84 geodetic coordinate system were emphatically analyzed. The results show that FindCM positioning performance is stable and reliable. It has real-time dynamic centimeter-level accuracy in the Binhai New Area,which is equivalent to the BHCORS performance precision.
