摘要
在实际项目中实验了Trimble RTX后处理在中国内陆解算精度,并且探索了基于RTX-PP获取CGCS2000坐标的可行性。实验结果显示:1)延长数据观测时长(实验数据12.15 h),RTX-PP的定位可优于1 cm精度;2)RTX-PP直接提供的CGCS2000解算结果精度在dm级别,而利用更高精度的速度场模型解算的CGCS2000坐标精度可以在cm级。
In practical projects,the accuracy of Trimble RTX post-processing in inland China is investigated,and the feasibility of obtaining CGCS2000 coordinates based on RTX-PP is explored. The experimental results showed that： 1） to extend the time of observation data（ experimental observation data length 12. 15 h）,the localization of RTX-PP can reach better than 1 cm accuracy; 2）CGCS2000 RTX-PP provides the accuracy of settlement results directly at the DM level,and the use of CGCS2000 coordinate precision field model to solve the higher precision of the speed can be at the CM level.
