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30min一次的RTK循环自动观测,共观测1 000次,历时连续20d,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1.7cm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%;plane mean square error is 1.5 cm;elevation mean square error is 1.7cm.
