Canadian MSat program moves out
Abstract
The probable technologies, configuration and applications of a mobile satellite telecommunications link system under development by Telesat of Canada are described. Operating in the WARC-approved 821-825 and 866-870 MHz bands in Canada and the U.S., respectively, the two nations would be covered with a two-beam system on the first generation, 5-m diam antenna spacecraft system. The second generation would have a 9-m antenna and accommodate 4/3 frequency reuse. Using 5 kHz intervals, each beam would need a gain of 4-8 dBi and a 5 W transmit power, thereby costing $3500-4500 or less for first generation equipment. A single satellite system, with ground control station and 35,000 mobile users, could be set up for $500 million. The users would be vehicle fleets, dispatchers, public telephones, data systems and paging services.
