ABSTRACT:
A satellite communication system wherein transmissions from a plurality of ground stations are transmitted via a satellite in a time-multiplex manner and where each station is assigned a particular time slot wherein for synchronizing a ground station into its time slot there is provided a time synchronizing means which first synchronizes the initial portion of the incoming stations transmission to a time delayed from its desired time after which when the signal has been accurately positioned to such delayed time it is shifted a pre-set time in its time slot such that the transmission from said incoming ground station is accurately positioned at its correct time slot.
