A method for the determination of coordinates of satellite navigation system signal observation points includes reconnaissance of the most close known points of geodesic network and survey object, placement of the points in question on the upper parts of constructions and outer parts of facades of buildings and on the Earth surface, determination of accuracy of coordinates of the most close known points, determination of needed accuracy of specific and head-of-the-line points in question, carrying out measurements, determination of coordinates of the head-of-the-line point in question with laying tacheometrical traverse from the most close known points of geodesic network. The reception of the signals of the satellite navigation system is carried out in two-three intermediate points placed in any point of flat roof of a house, at safe distance from its edge. Coordinates of specific points in question that are the tops of trihedral angles of intersection of facades and the plane of the upper horizontal edge of the wall are determined from intermediate points with direct analytical geodesic intersection. Coordinates of the head-of-the-line point in question on the Earth surface are determined from specific points in question with reverse analytical geodesic intersection, and necessity of use of satellite navigation system is determined by a given formula. |
