FIELD: instrument making.
SUBSTANCE: radio beacon simultaneously from two points spatially distanced in the plane of measurements with available coordinates radiates orthogonally linearly polarised electromagnetic waves with equal amplitudes, phases and wave lengths. At the same time information on angular position of the mobile object is contained in difference of phases between orthogonally linearly polarised electromagnetic waves received on board of the mobile object and is measured relative to equisignal direction that matches with the normal line to the middle of the base formed by transmitting antennas.
EFFECT: efficiency and accuracy of measurements with availability of strict limitations to dimensions of a receiving antenna of a mobile object, higher accuracy of measurements at equisignal direction and in directions close to equisignal one.
