METHOD OF CLOCK SYNCHRONIZATION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC G04R20/02 

FIELD: radio engineering, communication.

SUBSTANCE: device, implementing the proposed method contains the artificial earth satellite and five ground stations, each containing the frequency and time standard 1, heterodynes 2.1 and 2.2, the pseudo-random signal generator 3, the switch 4, the mixers 5, 13, 19, the amplifier 6 of the first intermediate frequency, the power amplifiers 7 and 12, the duplexer 8, the transmit and receive antenna 9, the clippers 10, 15, 33, 39 and 45, the buffer memories 11, 16, 34, 40 and 46, the amplifiers 14, 20 of the second intermediate frequency, the meters 17, 35, 41 and 47 delays and their derivatives, phase shifters 18, 21, 27 for 90º, the adders 22, 28 and 50, the multipliers 23, 29, the narrowband filters 24, 30, the amplitude detectors 25, 31, the switches 26, 32, 38, 44, the signal processing units 48.1, 48.2 and 48.3, units 49.1, 49.2 and 49.3 of time series formation of the total electronic content, the threshold unit 51, the computer 52.

EFFECT: extension of the functional capabilities of the known technical solutions by determining the propagation velocity and the direction of the ionospheric disturbance arrival, caused by various destabilizing factors, due to the restoration of the ionosphere total electron content spatial distribution according to the atmosphere continuous electromagnetic transmission probing data by the repeated signals.
