摘要
GPS定位技术是现代大地测量发展的重要标志,它可以直接精确地测定地面点的三维大地坐标。利用GPS定位技术所获得的三维坐标中的大地高分离求解正常高或海拔高,必须具有区域似大地水准面的成果。GPS快速、高效、高精度的技术特点,使得建立高精度高分辨率大地水准面的工作日益迫切,使其能和GPS大地高精度相匹配,实现替代水准测量的目的。
The GPS position technology is the modern geodetic survey development important symbol,which can survey decide the ground three dimensional geodetic coordinates directly and precisely.The ellipsoidal height in the three dimensional coordinates obtains which using the GPS position technology solves normal height or the elevation height by separation,must have the achievement of region to the geoid precision.The fast,highly effective,high accuracy technical characteristic of GPS,causes the work to establish the geoid precision high accurately and high resolution to be day by day urgently,enables its to match with the GPS accuracy ellipsoidal height,realization substitution level survey goal. This thesis integrates a project in my partment,analysises the ellipsoidal and the normal height linely in long region which obtained by GPS.At last,this thesis obtaines the relation in the ellipsoidal. and the normal height linely in long region.
