METHOD OF LOCATING OBJECTS FOR LOCAL NAVIGATION SYSTEMS Russian patent published in 2016 - IPC G01S5/10 G01C21/00 

FIELD: radar and navigation.

SUBSTANCE: invention may be used in navigation systems and local area networks to control the movement of mobile objects in local zones navigation. Method is based on generation by a navigation object two high-frequency harmonic signals with different frequencies, their simultaneous radiation from navigation object and reception in several reference radio navigation points with known coordinates, generation in said points of differential frequency signals received from a navigation object high-frequency signals, transmitting generated differential frequency signals in central processing station, where phase difference of differential frequency signals coming from different reference points results of measurements of phase differences taking into account mutual arrangement of central receiving station and reference radio navigation points are recalculated in coordinates of navigation object, wherein both generated on navigation object harmonic signals, before radiation, are synchronously phase modulated with same pseudorandom binary sequence with phase deviation of 180°.

EFFECT: high noise-immunity.
