摘　　要：为了分析2020与2005珠峰高程测量与确定过程中的异同,该文从GNSS数据处理、高程控制网数据处理、峰顶交会数据处理、峰顶大地水准面差距计算4个方面对其进行了异同比较分析,阐述了2020珠峰高程测量的技术进步与创新。分析表明,2020珠峰高程测量从测量装备的国产化、测量手段和数据的丰富性,数据处理的高精度等多个方面,较2005年都有长足的进步。同时,中尼合作开展数据处理,共同确定了基于国际高程参考系统(international height reference system,IHRS)的珠峰正高。Since the 21st century,China has surveyed the height of Mount Qomolangma in 2005and 2020respectively.This paper compares the similarities and differences between 2020and 2005height measurement and determination of Mount Qomolangma from four aspects:GNSS data processing,elevation control network data processing,summit intersection data processing,and calculation of the summit geoid separation.It also expounds the technical progress and innovation of the 2020height surveying of Mount Qomolangma especially.The results show that 2020height surveying of Mount Qomolangma has made great progress compared with 2005in terms of localization of measuring instrument,richness of measuring means and data,and high accuracy data processing.Moreover,China and Nepal collaborated on the data processing and jointly determined the orthometric height of Mount Qomolangma.
