| 摘 要： | 本文利用GPS连续观测资料,从单天误差、重复率统计两方面对比分析了Gamit/Globk中6种不同计算方案的结果,重点分析了参考框架的选取与约束,并总结了利于形变研究和形变信息提取的数据处理方案:对小的区域网形变分析而言,定框架时不宜使用过多的测站,应该选区域网周边较稳定的点做为框架点进行GLORG计算,通过IGS轨道...

| Abstract: | By using of GPS continuous observation data,and from the two aspects of single day error and repetition rate statistics,the paper comparatively analyzed the results generated by six kinds of different calculation schemes in Gamit/Globk,mainly analyzed the selection and restriction of reference frame,and summarized the data processing scheme which would be beneficial to deformation research and information extraction: For small regional deformation analysis,it is not suitable to select excess stations when c... |
