英文摘要：

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.
