中小城市连续运行参考站脱离水准测量应用研究

Application Research on CORS in Small and Middle-sized Cities with Leveling Off

文章结合泉州市连续运行参考站的建立实例,通过加入精化水准面模型和未加精化水准面模型两种实验数据比对,分析在建设CORS过程中,用精化水准面模型为基准才能得到更加精确的高程数据,中小城市在没有精化水准面模型前提下用坐标联测并进行高程数值拟合的方法求解出近似似大地水准面而得出的高程在测图方面也是可行的。

This paper uses the establishment instance of CORS in Quanzhou City,through the comparison of models with Quasi-geoid and models without Quasi-geoid,analyzes that during the building of CORS,using Quasi-geoid models as standard then we can obtain much more accurate elevation data.Without the Quasi-geoid in small and middle-sized Cities,it is also feasible in mapping to gain the elevation using coordinate connection survey and elevation fitting to calculate the Quasi-geoid.
