Abstract: Since the 1960s, China has carried out six geodetic campaigns (in 1966, 1975, 1992, 1998, 1999 and 2005 respectively) for the height determination of Qumolongma Feng (Mt. Everest, QF in short) independently or in cooperation with foreign countries. Geodetic field work, data processing and scientific researches have been executed in the campaigns. The height determination results of QF obtained by China in the past 40 years have been briefly introduced and reviewed in the paper. Emphases are given to the technical progress in the 2005 campaign. For example, GPS technique has been widely and precisely used, and the thickness of the snow-ice cover on the QF summit is measured by ground penetrating radar integrated with GPS. All these technical measurements really raise the accuracy and reliability for the height determination of QF and the thickness of the snow-ice layer on the QF summit. The orthometric height (height above sea level) of the snow surface of the QF summit is 8 847.93 m. T...更多he orthometric height of rock surface of the QF summit is determined as 8 844.43 m,and the thickness of the snow-ice layer on the QF summit is 3.50 m.
