珠穆朗玛峰高程测量

Qomolangma Height Surveying in 2005

综合利用GPS定位、水准测量、三角测量、电磁波测距、重力测量、雷达测地及大地水准面精化等技术,精确确定了珠峰顶的高程和平面位置,实现了迄今为止对珠峰高程最为精确的测量。介绍了珠峰高程控制网和GPS控制网的测量概况,阐述了利用常规大地测量和GPS技术确定珠峰高程的数据处理方法以及局部重力场精化等技术,为进一步研究珠峰地区板块运动提供了良好基础。

During the 2005 height determination of Qomolangma peak,the plane position and geodetic height of Qomolangma peak were determined precisely with the multipurpose use of GPS position-setting,leveling,triangular surveying,distance measurement with electromagnetic wave,gravitation surveying,radar geodesy and precise determination of geoid,which realized the most precise height surveying of Qomolangma peak so far.This paper mainly introduces the general surveying situation by leveling control network and GPS control network in Qomolangma peak,and describe the data processing using general geodesy and GPS as well as the technology of precise determination of local gravity field and so on.Moreover,favourable basis is provided for further study of the plate movement in the Qomolangma region.
