| 摘 要： | 介绍了利用EGM96重力场位模型,结合GPS水准数据,采用移去恢复(RCR)法求解未知点高程异常的方法.和用单纯的GPS水准拟合法相比,精度有明显改善,并与CG01C重力场位模型进行了对比.文中给出了具体计算步骤,并将拟合模型分为函数模型和随机模型进行说明,最后结合算例说明了此方法的可行性.

| Abstract: | Introducing the method of using the Earth's Gravity field model EGM96, integrating GPS level data,using the remove-compute-restore method to gain the elevation abnormality of unknown points. With comparing to the general fitting of GPS/leveling, the fitting precision is superior to improve, and contrasting with the model of CG01C. The paper has given the detailed calculation process, and divided the fitting models into functional models and statistical models to explain. Finally, the text has illuminated th... |
