利用联测IGS跟踪站方法提高GPS控制网起算数据精度

Application of the Methods to Connect IGS Tracing Station in Improving the Accuracy of GPS Control Network Data

详细讨论了利用联测IGS跟踪站提高GPS区域控制网起算数据精度的方法,并介绍了将区域控制网框架和国际地球参考框架ITRF2000相连的方法,探讨了联测IGS跟踪站时应注意的事项,并根据实例对采用联测IGS跟踪站后对GPS网起算点的精度影响进行分析。

This paper discusses the methods to connect the IGS tracing station and get IRTF 2000 coordinates for improving the accuracy of the control points during the establishment of the GPS network for remote areas.And it also discusses the issues should be paid attention in during the field operation and data processing.At last,it analyzes the precision of the fixed points after the IGS station connection.
