矿山GPS控制网的高程拟合

Height Fitting of Mine GPS Control Network

矿山控制网的布设,一般采用GPS静态技术解决平面控制的问题,而高程控制的问题则大多数采用电磁波测距三角高程的技术来解决。通过实际算例得出,在高山区矿区控制网布设中,利用GPS静态测量技术,通过增加起算点数量和采用曲面拟合的方法,能满足矿区控制网的高程精度要求。

In mine control network lay-out, static GPS survey technique is applied into the plane control, whereas the trigonometric leveling of the electro-magnetic distance measurement is applied into height survey. In mine control network, static GPS surveying technique can satisfy the precision requirement of control network height, through adding the amount of original points and using surface fitting method.
