A satellite communication system has a hub earth station and a plurality of terminal earth stations. Each inbound satellite communication link from a terminal earth station to the hub earth station carries digital data packets encoded in CDMA code for code division multiple access at a first bit rate during synchronized time slots on a contention channel. An outbound communication link from the hub earth station to the terminal earth stations sends time division multiplexed digital data at a second bit rate higher than the first bit rate. A number of systems may share the same hub, with each system using a different CDMA code.

Satellite communication network

A communication system includes a hub station and a plurality of terminal stations. An inbound satellite communication link from each of the terminal stations to the hub station sends digital data packets encoded with a CDMA code for code division multiple access during synchronized time slots on a contention channel. Each of the digital data packets is encoded with the same CDMA code during a first transmission, but each packet is encoded with an alternate CDMA code during any subsequent transmission.
