MODE OF DEFINITION OF THE SHORTEST DISTANCE AND DIRECTION TO AN ELECTRICITY TRANSMISSION LINE Russian patent published in 2008 - IPC G01S13/93 

FIELD: the invention is directed on increasing of accuracy of definition of the shortest distance and direction to an electricity transmission line.

SUBSTANCE: the indicated result is achieved due to the fact that aboard a flying vehicle they measure in a combined system of coordinates of mutually orthogonal components B₁, B₂, B_{3 .}of_{the vector of the induction of the magnetic field of the industrial frequency, calculate them into components Bx, By, Bz of the vector of the induction of the magnetic field in the Earth's mathematical Decart system of coordinates combined with the direction of the horizontal motion of the flying vehicle and on them they define the azimuth Z, the angle of place E and the shortest distance D to the electricity transmission line according to proposed formulas in which they register the current and the previous meaning of the vector of the induction of the magnetic field, effective altitude of the suspension of the wires of the electricity transmission line over the surface of the Earth and also the orientation of the flying vehicle, the altitude over the level of the sea and its horizontal speed.}

EFFECT: increases accuracy of definition of the shortest distance and direction to an electricity transmission line.
