基于LGO与CosaGPS的高铁CPI复测技术研究

Research on the Application of LGO and CosaGPS in Repetition Survey of High-speed Rail's Basic Horizontal Control Network

简要介绍了利用LGO进行基线解算和Cosa GPS进行网平差的操作流程,并利用这两个软件实际处理了京沈高速铁路某标段的CPI平面控制网的复测数据,展示了LGO和Cosa GPS两者协同处理数据时的高精度和高效的特性。对类似的高等级控制网解算有一定的借鉴意义。

This paper briefly introduces the usage of LGO and CosaGPS, and used the two software actual processing a program. The program is a part of basic horizontal control network of the Beijing - Shenyang high - speed Rail. It shows the two software＇S high preci- sion and high efficiency. And can be referenced by the relevant project.
