METHOD OF LOCATING NAVIGATION OBJECT Russian patent published in 2016 - IPC G01S13/00 

FIELD: radio navigation.

SUBSTANCE: invention relates to radio navigation and can be used in local navigation systems and networks for controlling movement of mobile objects in local navigation areas. Specified result is achieved by the fact that the method is based on emitting by object of navigation of a high-frequency harmonic signal, its reception in several reference radio navigation points with known coordinates, at that from the navigation object during the given time interval additionally emit a second high-frequency harmonic signal, frequency of which differs from the frequency of the first high-frequency harmonic signal by a given value, in each of the reference radio navigation points that signal is received together with the first, form from received signals the signals of different frequency, transmit the generated signals to central processing station, where is measured the phase difference of the signals of difference frequency received from different reference points, and these measurement results are fixed, all the described actions, starting from the radiation of the second high-frequency harmonic signal are repeated, having changed the frequency of the second harmonic of high-frequency signal so that the new difference frequency increased approximately an order, interval of the same time, during which the frequency of the second harmonic signal remains constant, selected sufficient for measuring phase difference of differential frequency signals received from the reference radio navigation points, upon completion of measurements of all fixed values of phase differences are recalculated in coordinates of navigation object taking into account mutual arrangement of the central processing station and reference radio navigation points.

EFFECT: achieved technical result - increase of accuracy of determining coordinates of navigation object.
