OBJECT COORDINATES DETERMINATION METHOD Russian patent published in 2017 - IPC G01S13/06 

FIELD: measurement equipment.

SUBSTANCE: radio signals transmitted by the ground stations with the specified coordinates of phase centers of their antennas, are formed as harmonic oscillations with frequency predetermined for each station, modulated functions as a product of at least two functions, each of which may be sinusoidal or cosinusoidal, with the set frequency of the first and subsequent functions. At the object, quadrature reception is performed with the given oscillator frequency, relative delay times are determined for radio signal reception from stations in the timing system associated with the object, and according to the set spatial coordinates of station antenna phase centers and relative distances from them to the object, obtained by the corrected relative time of radio reception delay, the spatial coordinates are uniquely determined of the antenna phase center of the object located in any point in space.

EFFECT: improved accuracy and reliability of the spatial coordinates measurement of functionally related objects.
