METHOD OF CALIBRATING TIME SCALE Russian patent published in 2014 - IPC G04R20/00 

FIELD: physics.

SUBSTANCE: equipment of a mobile facility of a control and monitoring centre implementing the method according to the invention comprises a frequency and time standard, two heterodynes, a pseudonoise signal generator, a switch, an OR element, two mixers, a first intermediate frequency amplifier, two power amplifiers, a duplexer, a transceiving antenna, a second intermediate frequency amplifier, first and second clippers, first and second buffer storages, a device for measuring delay and derivatives thereof, a multiplier, a bandpass filter, a phase detector, an onboard controller, a master generator, a phase-shift modulator, sensors which characterise the technical state of the mobile facility, an onboard recorder, a receiving antenna, a power amplifier, a mixer, a second intermediate frequency amplifier, a multiplier, a bandpass filter, a phase detector, a first narrow-band filter, a phase inverter, an adder, a frequency selector, a second narrow-band filter, an amplitude detector, a threshold unit and a switch.

EFFECT: high selectivity, noise immunity and reliability of two-way communication between a monitoring and control station and mobile facilities by suppressing spurious signals received over additional channels.
