FIELD: radio engineering, communication.SUBSTANCE: invention can be used in very long baseline radio interferometry, as well as in the frequency and time synchronisation service. The device which carries out the disclosed clock synchronisation method includes a frequency and time standard 1, first 2.1 and second 2.2 heterodynes, a pseudorandom signal generator 3, a switch 4, first 5 and second 13 mixers, a first intermediate frequency amplifier 6, first 7 and second 12 power amplifiers, a duplexer 8, a transceiving antenna 9, first 10, second 15, third 32, fourth 33 and fifth 34 clippers, first 11, second 16, third 35, fourth 36 and fifth 37 buffer storage devices, a second intermediate frequency amplifier 14, first 17, second 38, third 39 and fourth 40 devices for measuring delay and derivatives thereof measuring, a first summation frequency amplifier 18, a second summation frequency amplifier 19, first 20, second 21, third 28 and fourth 29 amplitude detectors, first 22, second 23, third 30 and fourth 31 switches.EFFECT: wider operating frequency range without expanding the frequency tuning range of the second heterodyne and simultaneous duplex radio communication with multiple ground-based stations using additional receiving channels.2 cl, 4 dwg |
