APPARATUS FOR MEASURING ORIENTATION AND INCLINATION OF GEOLOGICAL STRUCTURE SURFACE BY USING TWO GNSS ANTENNAS AND ORIENTATION AND INCLINATION MEASUREMENT METHOD USING SAME

摘要

The present invention relates to a method for easily measuring the orientation and inclination of a geological structure surface by using two GNSS antennas, including (a) measuring primary measurement phase center coordinates of first and second GNSS antenna units and secondary measurement phase center coordinates of the first and second GNSS antenna units measured after base line arrangement in a direction orthogonal to the direction of the base line during primary measurement with a measuring device in which the first and second GNSS antenna units are fixed at both ends of the base line formed along the longitudinal direction of a case; (b) deriving coordinates of three points on the geological structure surface through the primary measurement phase center coordinates and the secondary measurement phase center coordinates; (c) obtaining a normal vector of a plane to which the derived three points belong; (d) deriving an orthogonal vector and its unit vector in the X-Y plane through the normal vector of the plane; (e) calculating an orientation value through an orthogonal vector in the X-Y plane and a Y-axis direction unit vector; and (f) calculating an inclination value through the normal vector and the Z-axis direction unit vector.;COPYRIGHT KIPO 2019
