Telematic services via satellite in Europe
Abstract
Telematics in Europe is intended to provide service through five satellites: Eutelsat, Telecom 1, Unisat, DFS, and Italsat. A 'Central Europe' zone will have coverage from the five satellites simultaneously; Eutelsat will be at the hub of the network and will have the largest coverage of all. Two to five transponders per satellite are to be used for telematic special services on the 12.5-12.75 GHz down-link band; Italsat will use a 20 GHz down-link. The ground segment will use several hundred small 3.5 m dish antennas and SCPC or 25-60 Mb/s TDMA equipment. Among many services, telematics will include videoconferences, computer-to-computer data transfer, high speed facsimile, and transatlantic digital business. Although all five networks will operate independently, future interconnection among them will allow efficiency improvements.
