METHOD FOR LOCKING INTO SYNCHRONISM PSEUDONOISE SIGNALS ON DELAY AND DEVICE FOR REALISING SAID METHOD Russian patent published in 2011 - IPC H04L7/00 

FIELD: physics, radio.

SUBSTANCE: invention relates to radio engineering and specifically to transmission of information in space command radio links which use pseudonoise signals. At the receiving side, the j-th phase of the reference signal is linked to a network of time pulses of a local time scale which is synchronised from the navigation signal receiver of the GLONASS system (GPS), and the j-th phase of the pseudonoise signal is transmitted in advance on the time for propagation on the communication channel from the transmitting side and corrections of time mismatch is transmitted between the receiving and transmitting sides, where during switch to the mode for tracking the received signal, jam sync of the phase of the reference signal is switched off. The device for locking into synchronism pseudonoise signals on delay has an N-channel quasi-optimum pseudonoise detection circuit, a GLONASS system (GPS) navigation signal receiver, a frequency standard, a local time scale, an AND circuit, a digital inverter, a unit of switches, RAM, all connected to each other.

EFFECT: cutting on time for locking into synchronism during successive search and cutting on the number of channels for parallel search for pseudonoise signals.
