METHOD FOR JOINT DETERMINATION OF COORDINATES, HEIGHTS AND DIRECTIONAL ANGLES Russian patent published in 2023 - IPC G01C1/02 G01C3/02 

FIELD: measuring technology.

SUBSTANCE: invention can be used in geodetic works. Reference networks are created in the execution area in the form of triangles fixed on the ground by reference marks (RM). Then two goniometers are installed on tripods outside the centres of the starting points, and the third device is inside the network being created. According to the measurements on the RM of the original network, the orienting angles of the first and second devices, their coordinates and heights are determined. An unmanned aerial vehicle (UAV) of a helicopter type is brought out sequentially at three points to a height at which its visibility is ensured from the points of the initial and created geodetic network. Horizontal and vertical directions on the UAV are synchronously measured with three instruments; the coordinates of the UAV are calculated by the long-base method, and the height of the UAV is calculated by trigonometric levelling. The directional angles of the directions of the overhead lines between the positions of the UAV are calculated. Upon completion of measurements on the UAV, an additional third device measures the elevation, direction and distance to the stationary sighting marks of the points of the network being created.

EFFECT: reduced labour costs and increased efficiency of geodetic work.
