SATELLITE RADIO NAVIGATION SYSTEM OF LANDING USING PSEUDOSATELLITES Russian patent published in 2012 - IPC G01S19/11 H04B7/185 

FIELD: radio engineering.

SUBSTANCE: on board of aircrafts there is a retransmitter of pseudosatellites signals, which comprises a board receiver of pseudosatellites receiver from a receiving antenna of the retransmitter facing towards the Earth at the inlet, step-down frequency converters that increase frequency converters, units of capacity limitation, a board transmitter of converted pseudosatellites signals with a transmitting antenna of the retransmitter at the outlet, and a frequency synthesiser, at the same time the board receiver of satellite signals is a standard navigation receiver of satellite signals with a board receiving antenna at the inlet, and information communication is carried out with the pseudosatellites. Also a version of the system is proposed, differing by higher range of action due to additionally included unit of automatic capacity adjustment, calculator of distances from an aircraft to each pseudosatellite and functional converter of distance into a signal level.

EFFECT: higher reliability of air craft landing system using a standard navigation receiver of satellite signals.
