The paper introduced geoid status in southwest region of Tarim Basin that is low precision in distance difference of geoid and even absent and its effect on precision of oil geophysical prospecting, brought up that in order to transform geodetic height measured from GPS to sea level elevation. It needs to transform geodetic height in GPS 84 coordinate to geodetic height in Beijing 54 coordinate, and then obtain sea level elevation after adding difference of geoid to geodetic height in Beijing coordinate. It has been adopted 7 known heights of state-control point in the area in the paper and used second curved surface fitting to calculate GPS sea level of whole grid. The fitting results basically meet the need for oil exploration. Meanwhile made a suggestion on ultimately solving the geoid problem in the area.

本文介绍了塔里木盆地西南部地区大地水准面差距值精度偏低甚至为空白的现状及其对石油地球物理勘探的影响 ,提出了由 GPS测量得到的大地高转换成海拔高 ,需将 WGS84坐标系大地高转换成北京 5 4坐标系的大地高 ,再将北京 5 4坐标系大地高加大地水准面差距值后得到海拔高程。文中采用该地区已知的 7个国家控制点高程 ,用二次曲面拟合归算全网 GPS的海拔高程 ,拟合结果基本满足石油勘探的要求 ;同时对最终解决这一地区的大地水准面问题提出了建议。

In order to solve the shelter problem of GPS network and state control points conjunction, a method of constructing virtual vector was put forward in this thesis. By using constructing elements between GPS net work point and state control point determined by ordinary survey instruments and making use of converting formula of the WGS-84 coordinate system and occupation station original based grid system, the WGS-84 coordinates of the state control point were calculated. Then the virtual vectors are constructed...

In order to solve the shelter problem of GPS network and state control points conjunction, a method of constructing virtual vector was put forward in this thesis. By using constructing elements between GPS net work point and state control point determined by ordinary survey instruments and making use of converting formula of the WGS-84 coordinate system and occupation station original based grid system, the WGS-84 coordinates of the state control point were calculated. Then the virtual vectors are constructed according to the format of GPS process programmer and put into whole GPS network.

针对GPS控制网与国家控制点联测时遮挡严重的问题,提出了一种虚拟基线的方法,即通过常规方法测出GPS网中某点与国家控制点之间的基线构造元素,并利用WGS84地心坐标系与站心地平直角坐标系之间的转换模型计算出国家控制点的WGS84地心坐标,然后根据GPS商业处理软件的基线格式构造出GPS网中某点与国家控制点之间的虚拟基线,并入整个GPS控制网中进行平差解算.从而解决了与国家控制点联测时因遮挡等原因GPS基线不合格或质量不高而使整个控制网精度下降的问题.并通过实例对其进行了检验,达到了较好的效果.

Starting from the problems encountering in GPS net work establishment and linking with the national control points, the rational disposal of observation program for GPS control net work is discussed under such conditions as under the targets , near obstacles, etc The relation accuracy factor concept and betterment way are put forward It has certain guidance in practice
