摘要
介绍了重庆市GPS监测网的建设。①由12个GPS观测站同“中国地壳运动观测网络”相联的重庆市GPS监测网,构成了一个覆盖全重庆市的高精度、高时空分辨率、准动态的三维地壳运动观测网。②重庆市GPS监测网观测资料,利用GAMIT/GLOBK9.93(Linux)软件进行数据处理,采用松弛解处理模式和精密星历,并利用IGS跟踪站进行约束。③GPS观测资料经整体平差后,基线长度中误差小于4mm,基线相对中误差为10-9量级。
In this paper, GPS observation network of Chongqing City is reported. ①This network is three dimension crust movement observation network of a high accuracy and high space-time resolution and Qausi-dynamic, it is constructed by 12 GPS observation post and “Crust Movement Observation Network of China” （CMONOC）. ②Observation data are processed by GAMIT/GLOBK 9.93（Linux） software, which is adopted relax calculation dealt mode and precise ephemeris, proceed bind with IGS track station. ③GPS observation data have perfbormed an Integral adjustment, baseline length precision is better than 4mm, baseline correspondent precision is 10^-9 grade.
