宁波市网络RTK应用的可靠性及精度研究

摘要

应用NBCORS在其覆盖范围内的鄞州中心区某已知点上进行每隔30 min一次的RTK循环自动观测,共观测1 000次,历时连续20 d,通过对观测数据可靠性和精度的分析,得出NBCORS的可靠性为99.9％,精度为平面中误差1.5cm、高程中误差1.7 cm的结论.%Within NBCORS coverage downtown area in Yinzhou, on a known point once every 30 min observation RTK circulation is done, 1 000 total observations,which lasted more than 20 consecutive days and nights. Through the analysis of observational data, obtained conclusions that reliability of NBCORS is 99. 9% 5 plane mean square error is 1. 5 cm; elevation mean square error is 1. 7cm.
