摘要
结合工作实际,提出了3种基于不同间距的控制点定点方法 :伪距法单点定位、RTK测量技术、非差相位精密单点定位(PPP),其中PPP方法可以实现m级间隔的野外控制点确定,对控制网改造和野外找点具有一定的指导意义。
Combined with practical work,we put forward several methods to confirm the control points based on different spacing.The result shows that the non difference carrier phase precise point positioning(PPP) method can determine the control points in meter interval,and has a certain guiding significance for control network reconstruction and field to find points.
