Abstract

In the method of multiple-station communication for low-orbit satellite systems, according to which service information modulated pseudirandom synchronization signals are emitted from a satellite transponder over the entire band of the transmission spectrum, information packets are received. from user stations, mismatches by frequency and delay are measured, and the mismatches and information portions of the packets are memorized, they are reswitched and reemitted with spatial, frequency- and time-division multiplexing; all the user stations receive the synchronization signals and the information packets assigned to them, with the transmitters being autotuned by frequency and delay with multibase information encoding; there are provided high-orbit satellite transponders for integration with the low-orbit satellite transponders; search of signals and initial synchronization of channels owing to linear discrete scanning of the clock-frequency signals of the user station transmitters with compensation for the Doppler shift by the clock frequency, evaluations of the instants of correlation convolutions of the relayed signals with reference signals in two points by each user, calculation of the number of the scanning steps between the convolutions and evaluation of the delay introduced into the emitted signal.
