摘要: 应用网络工程GPS基准站每周的数据,按非基准方法求得区域解和全球解,分析研究了基准站坐标位置及速度场的变化规律,并给出了站坐标和速度场精度的统计分析结果。结果显示,坐标分量的变化趋势为线性,坐标残差的变化为随机曲线,可靠地剔除野点后,速度场信息及其精度可靠且优于点位坐标精度。Abstract: On the basis of the observations at GPS fiducial station of crustal movement monitoring network of China from 1999 to 2001, obtained by the result of global solutio and local solution, the changing tendency of GPS fiducial station coordinate and velocity field is anasolution, the changing tendency of GPS fiducial station coordinate and velocity field is analyzed.The statistical result of accuracy of GPS coordinate and velocity field is given.
