The present invention relates to a system for checking the existence of a GPS geodetic survey change per each control point caused by a precise geomorphic survey and is provided to enable a precise survey for confirming geodetic survey changes in the control points by improving the receiving sensitivity by adjusting the height of an antenna. Furthermore, the present invention stably and easily moves a GPS surveying instrument to a measuring position, thereby improving user convenience and preventing damage to the GPS surveying instrument. |
