METHOD OF TECHNICAL MAINTENANCE OF VEHICLE LOCATION MANAGEMENT DURING RECOVERY OF INFRASTRUCTURE OBJECTS AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2020 - IPC G08G1/00 G01S1/02 B61L1/02 B61L25/02 

FIELD: positioning systems.

SUBSTANCE: invention relates to a logistics management systems based on a global positioning system. Logistics system with control of vehicle location implementing proposed method comprises global system of vehicle positioning on railway track, satellites, a power supply connected to the solar battery panel from photoelectric converters, actuators, a GPS signal receiver, a microprocessor and a modem. First and second modems comprises microprocessor, master oscillator, phase manipulator, first heterodyne, first mixer, first intermediate frequency amplifier, first power amplifier, duplexer, transceiving antenna, second power amplifier, second heterodyne, second mixer, second intermediate frequency amplifier, multiplier, band-pass filter, phase detector, oscillatory circuit, narrow-band filter, amplitude detector, threshold unit and switch.

EFFECT: higher noise-immunity of duplex radio communication.
