METHOD AND SYSTEM TO LOCATE MOVING TRANSPORT FACILITIES Russian patent published in 2011 - IPC G01S5/00 

FIELD: transport.

SUBSTANCE: proposed system comprises transceiver of the main transport facility to transmit first signal to first repeater and second repeater communicated with secondary transport facility. First repeater antenna and second repeater antenna are connected with reference points of secondary transport facility. First signal received, first repeater transmits second signal to first beacon of the main transport facility and to first transceiver. Transmitter antenna and first beacon antenna are communicated with reference points of the main transport facility. First signal received, second repeater transmits third signal to first beacon and to main transceiver. Data processor or estimation unit estimate relative position of the main transport facility with respect to secondary transport facility proceeding from reference points of the main and secondary transport facility reference points and definite run times.

EFFECT: correlation and coordination of primary and secondary positions of transport facility.
