METHOD OF DETERMINING COORDINATES OF OBJECT Russian patent published in 2017 - IPC G01S5/10 H04W64/00 

FIELD: radio engineering, communication.

SUBSTANCE: stations of a transmitting system that are stationary or moving as a unit, arranged in a predetermined manner in a three-dimensional Cartesian coordinate system associated with the transmitting system, synchronously transmit radio signals with known on the object for each radio signal by time shifts of transmission in a given time reference system associated with the transmission system, and on the object they are received in the time reference system associated with the object, the moments of the reception times are recorded, the relative time deposits the reception of radio signals from stations and correcting them taking into account time shifts. According to the corrected relative time delays in the reception of radio signals, the relative ranges are determined and, according to the expressions given in the claims, the distances from the antenna phase centers (FCA) of the stations to the FCA of the object are determined. From the given spatial coordinates of the FCA of the stations and the indicated distances, the spatial coordinates of the FCA of the object in the indicated coordinate system are determined.

EFFECT: increasing the accuracy and reliability of determining the spatial coordinates of objects.
