摘要
以往对常规测量数据进行处理时,常采用平面与高程分别平差得出珠峰峰顶(山头或觇标)相应于某椭球的平面位置(经纬度)与大地高。提出采用平面与高程进行联合处理的方法,并就这两种方法采用的模型、数据处理方法及最终结果(主要是大地高)进行讨论与分析,并与GPS的结果进行比较,分析其差异。
The plane position and geodetic height of peak or target of Qomolangma corresponding to ellipsoid was obtained separately through triangulation network adjustment and height adjustment when processing traditional survey data in Qomolangma height measurement before. The paper puts forward to do adjustment with combined data from triangulation network and trigonometric leveling . The math model, data processing method adopted in separate adjustment and combined adjustment are discussed here. The final results in these two different adjustment is also analysed and compared with GPS results. The difference between traditional method and GPS is discussed in detail in this paper.
