模拟大地水准面应用于GPS水准内插的研究

Application of Simulated Geoid to GPS-Leveling Interpolation

  • 摘要: 采用移去 恢复技术和多面函数法对已知GPS水准数据进行了内插处理。试验结果表明,利用实际地球物理资料得到的模拟大地水准面精度最高

     

    Abstract: According to the topography\|isostatic theory, an isostatic\|geoid can be calculated; at the same time, the model\|geoid can be derived directly from earth's gravity field model. In this paper, the "remove\|restore" technique and multi\|quadratic function are used to interpolate the known GPS/leveling data. The experimental results show that the accuracy of simulated geoid by practical geophysical data is better than other geoids.
