| 摘 要： | 小区域的工程建设中,为充分利用GPS测得的大地高成果,通常采用几何拟合法和移去恢复法计算当地的大地水准面模型,通过具体算例对常用的拟合模型和几种移去恢复法进行分析比较,提出基于CQG2000的移去恢复法,试验表明该法较其它方法精度有明显提高。

| Abstract: | In order to fully use GPS measures achievement,we generally calculate geoid model with geometrical fitting and remove-restore method in small area engineering construction and compare several kinds of fitting model and remove-restore algorithms.The research deals with geopotential mode CQG2000-based remove-restore method,and has obvious accuracy rise in the experiment. |
