| 摘 要： | 结合GPS控制网和三等精密水准网的对比试验,构建了GPS测高技术中高程拟合模型,据此对锦赤铁路三标段工程项目进行分析。实例中选取多项式曲面拟合方法,进行高程内插计算,并将拟合结果与水准测量结果进行对比,结果表明：GPS高程拟合的内、外符合精度完全满足铁路工程精度要求,精度可达到2～3cm。

| Abstract: | Through comparative trial of GPS control network and third order precise leveling network,has modeled elevation fitting model in GPS altimetric surveying technology,hereby carried out analysis of the Jinzhou-Chifeng railway third bit lot engineering project.In the instance,polynomial surface fitting has selected to carry out elevation interpolating,and compare the fitting results with leveling measured results.The result has demonstrated that： internal and external accordant accuracies from GPS elevation fitting can fully satisfy requirements of railway engineering with accuracy 2~3cm. |
