METHOD FOR CLOCK SYNCHRONIZATION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC G04C11/00 

FIELD: radio engineering, communication.

SUBSTANCE: device for synchronizing clocks that implements the inventive method comprises a center (40) for information processing and three ground points A, B and C, each of which comprises a standard (1) of frequency and time, heterodynes (2.1 and 2.2), a generator (3 ) of pseudorandom signals, a switch (4), mixers (5, 13, 19, 28, 30), an amplifier (6) of the first intermediate frequency, power amplifiers (7 and 12.1), a diplexer (8), a two-way transmission antenna (9), clippers (10 and 15), buffer memories (11 and 16), a meter (17) of delays and their derivatives, a phase shifter (18) for 90°, amplifiers (14 and 20) of the second intermediate frequency, a phase shifter (21) for -90°, an adder (22), multipliers (23 and 34), a narrowband filter (24) and an amplitude detector (25), a key (26), a unit (27) of reference frequencies, an amplifier (19) of the third intermediate frequency, filters (31 and 35 ) lower frequencies, a meter (32) of Doppler frequency, a correlator (33), an optimizing peak-holding controller (36), a unit (37) of variable delay, a indicator (38) of distance and communication lines (39.1, 39.2, 39.3). The information processing center contains phase doublers (41.1, 41.2 and 41.3), dividers (42.1, 42.2 and 42.3) of phase by two, narrow-band filters (43.1, 43.2 and 43.3), phase meters (44.1, 44.2 and 44.3), correlators (45.1, 45.2 and 45.3), multipliers (46.1, 46.2 and 46.3), filters (47.1, 47.2 and 47.3) of lower frequencies, optimizing peak-holding controllers (48.1, 48.2 and 48.3), adjustable delay units (49.1, 49.2 and 49.3) and a computer (50).

EFFECT: improved accuracy of synchronization of remote time scales by precise and unambiguous measurement of angular coordinates of the satellite relay and improved accuracy of determination of its location and movement in space.
