Issue Date: | 2003 | Source: | 地球物理學報 (Chinese journal of geophysics), Sept. 2003, v. 46, no. 5, p. 595-599 | Abstract: | 从分析GPS技术在确定地球形状中的作用入手 ,论述了建立一类新的大地边值问题———GPS 重力边值问题的意义 ,给出了GPS 重力边值问题的定义及数学描述 ,推导出GPS 重力边值问题的逼近解式 ,并给出了应用GPS 重力边值问题确定 (似 )大地水准面、地面垂线偏差及外部重力场的基本公式 .对GPS技术用于物理大地测量的优势及有待解决的问题进行了简要归纳 . A new geodetic boundary value problem: GPS/Gravity-BVP is studied in this paper. Firstly, the definition and integral equation of GPS/Gravity-BVP are given, then an approach solution of GPS/Gravity-BVP is obtained. Also, the formulas for determining quasi-geoid, deflections of the vertical and external gravity field are given by use of the solution of GPS/Gravity-BVP. Furthermore, the advantages and problems of GPS/Gravity-BVP in physical geodesy are discussed. |
Keywords: | GPS/ Gravity-BVP Integral equation Quasi-geoid Deflections of the vertical External gravity field. |
