| 摘 要： | GPS定位技术发展日趋成熟,已被广泛应用于各项工程建设中,GPS平面精度很高但高程精度还不能满足某些工程的要求,精度较高的工程大多由水准测设高程。针对某具体项目测设的GPS拟合高程与水准测量的高程,通过比对两者观测数据,分析两者的精度,得出小范围平坦地区可用GPS拟合高程代替水准高程。

| Abstract: | The current GPS technology gradually become mature and has been widely used in engineering construction, the GPS plane precision is accurate but elevation precision can＇t meet some engineering requirements, high standard of accuracy engineering is mostly set by the leveling surveying. The elevation of GPS measurement and the leveling surveying based on a project is analyzed. By comparing both observation data, the conclusion is got that GPS fitting elevation can instead of the leveling surveying in flat small range. |
