LEASAT (Syncom IV)
The five satellites of the 1980s Leasat (Leased Satellite) program (Leasat F1 through Leasat F5) were alternatively named Syncom IV-1 to Syncom IV-5. These satellites were considerably larger than Syncoms 1 to 3, weighing 1.3 tonnes each (over 7 tonnes with launch fuel). At 4.26 meters (14.0 ft), the satellites were the first to be designed for launch from the Space Shuttle payload bay.
Hughes was contracted to provide a worldwide communications system based on four satellites, one over the continental United States (CONUS), and one each over the Atlantic, Pacific, and Indian oceans. Five satellites were ordered, with one as a replacement. Also part of the contract were the associated control systems and ground stations.
Anik-D2
The Anik satellites are a series of geostationary communications satellites launched by Telesat Canada for television in Canada, from 1972 through 2007. Some of the later satellites in the series remain operational in orbit, while others have been retired and are derelict. In Inuktitut, Anik means "little brother".
Anik D1 & D2 series C-Band satellites were launched in 1982 and 1984. They were based on the Hughes 376 design. Anik D1 carried the CANCOM package - a group of television signals for use by cable companies.
