摘要
接收机是全球导航卫星系统实现导航定位的终端仪器,不同型号GNSS接收机RTK测量精度与周围环境条件相关。选取4种不同型号的双频GNSS接收机,分别在良好的观测环境和特殊观测环境下,采用CORS模式进行RTK观测,并对观测数据进行粗差检验和处理,分析其测量精度及影响因素,结果表明不同型号GNSS接收机在不同环境下RTK测量精度和稳定性有所差异,不同观测环境对接收机RTK测量精度影响程度不一致,以期为工程实践中仪器的选择提供参考。
In this paper, we selected four different types of dual-frequency GNSS receivers, and used CORS mode to do RTK observation in good observation environment and special observation environment respectively. Then, we tested and processed the gross error of the observed data, and analyzed the measurement accuracy and influencing factors. The results show that different types of GNSS receivers have different RTK measurement accuracy and stability under different environments. The impact of different observation environment on receiver RTK measurement accuracy is inconsistent. This study can provide a reference for the selection of instruments in engineering practice.
