Abstract
A communication system comprising a satellite, a master earth station (MES), and a plurality of small earth stations (SESs) provides signal transmissions addressed and transmittable to a selectable other SES via the satellite, the MES, and then the satellite again. The signal transmissions consist of bit representing pseudo random sequence (PRS) signals PRS.sub.SES which in turn consist of chips arranged in predetermined and identifiable patterns and with the bit and chip occurrence rates C.sub.SES and B.sub.SES of each SES being synchronized with each other as they arrive at the MES. The satellite responds to the signal transmissions from the SESs to retransmit the signal transmissions to the MES, which in turn responds to the signal transmissions from the satellite to amplify and retransmit such signal transmissions back to the satellite again. The satellite again responds to the signal transmissions from the MES to retransmit them to the SESs. The MES and SESs further include apparatus to maintain synchronism between the chip and bit rates of the PRS.sub.SES signals as they arrive at the MES.
