Arrangement for transmitting digital information by satellite from a plurality of ground stations

摘要

The transmission system includes a uplink channels (2a-6a,2b-6b,3n-6n) for sending digital information packets, e.g. MPEG-2 video data, from a number of ground stations to a satellite, using different frequencies. A module on the satellite receives and reformats the digital information. The information is then broadcast to earth using a time division multiple access downlink.
