BROADBAND PHASE-DIFFERENTIAL LOCAL RADIO NAVIGATION SYSTEM Russian patent published in 2016 - IPC G01S5/00 G08G1/123 G01S3/46 

FIELD: radar ranging and radio navigation.

SUBSTANCE: invention relates to radio navigation and can be used in local navigation systems and networks for controlling the movement of mobile objects in local navigation areas. Mentioned result is achieved due to, that the system comprises arranged on the navigation object a support quartz generator, a frequency divider, a generator of pseudorandom binary sequence, two frequency synthesizers, two phase modulators, two amplifiers of high-frequency signals, a common transmitting antenna, three receivers, three receiving antennae installed in the reference radio navigation points with known coordinates, three measurement channels (differential frequency forming channels),three phase detectors, three analogue-to-digital converters and a computer of coordinates of the navigation object, herewith each of the measuring channels comprises a balance mixer, a narrow-band filter, a limiting amplifier and a resonant amplifier. Listed components are connected to each other in a certain manner.

EFFECT: higher noise-immunity of the system and higher accuracy of determining coordinates of a navigation object.
