2005珠峰测高GPS测量及其数据处理

GPS Data Processing of the 2005 Qomolangma Height Surveying

介绍了各种不同GPS测量的特点和数据处理方法,结合珠峰峰顶GPS观测自然环境恶劣的特点,分析了各种计算方案,确定了一种合理的解算珠峰高程的GPS数据处理方案,取得了较为满意的计算结果。

The determination of geodetic height at the Qomolangma peak is one of the very important tasks in the 2005＇Qomolangma height surveying. There are three GPS networks in the 2005＇Qomolangma height surveying, regional GPS crustal deformation network, geodetic GPS control network, and GPS measurement at the Qomolangma peak. The data collection and data processing were introduced in the paper. The final data processing strategy and reasonable geodetic height were fairly determined based on the careful data analysis.
