基于NBCORS网络RTK的误差分析与质量控制

Error Analysis and Quality Control Based on NBCORS Network RTK—Setting Ningbo City as an Example

摘要:

基于宁波市连续运行卫星定位服务系统，通过对影响网络RTK测量时GPS卫星信号传播带来的对流层延迟、电离层延迟以及多路径效应误差分析，提出了减弱和消除其误差影响的有效质量控制措施，旨在提高网络RTK定位技术的测量精度。

Abstract:

Based on Ningbo Continuous Operating GPS system, though analysis on the tropospheric delay, ionospheric delay and multi[CD*2]path effects of GNSS satellite signal propagation error of Network RTK measurement, effective quality control measurements in order to weaken and eliminate the impact of errors have been put forward in this paper. Thus, measurement accuracy of the network RTK positioning technology can be improved.
