Historical Development: The Alouette Program
In the 1950\u27s at the height of the Cold War, Defence Research Bureau (DRB) laboratories, located in Ottawa, were involved in research and development to keep Canadians abreast of leading edge technology and ensure that Canadian forces were adequately equipped for their defence role
Historical Development: Hermes Satellite
In the early 1960\u27s, international communication satellites using the 6/4 GHz bands and positioned in the geostationary satellite orbit were found to be capable of providing high quality telecommunications services. Domestic satellite communications systems were planned and were implemented, beginning in 1972, with the Telesat Canada ANIK-A System
Historical Development: MSAT Program
As early as 1967, Canadian researchers had been involved in trials with the U.S. on the use of UHF satellites for mobile services primarily for defence operations. The use of UHF frequencies, with satellites such as LES-5, LES-6 and TACSAT offered the possibility of small lightweight mobile or transportable terminals, and several demonstrations were carried out in the land, maritime, and aeronautical environment. The world\u27s first direct aircraft-to-aircraft voice communications via satellite was carried out May16, 1970 between two Canadian DND aircraft
Historical Development: Anik A Series
The Department of Communications of the Federal Government ran a competition across Canada to name Telesat\u27s first series of satellites. In November 1969, the winner of the contest was announced. A St. Leonard, Quebec, supermarket employee, Mary Frances Czapla suggested ANIK which means brother in the language of the Inuit. It was selected as the winning entry by a panel of judges which included Marshall McLuhan
SatCom Today in Canada: Communications Research Centre
The Communications Research Centre has been committed to applied and basic research in communications and related technologies since the late 1940s. Over the last 50 years many scientific and engineering milestones have been achieved, contributing to Canada\u27s position as a world leader in wireless and satellite communications and broadcast technologies
Historical Development: Anik B Hybrid Systems
Because of the success of the Hermes program and under an arrangement between Telesat Canada and the federal government, the next satellite commissioned by Telesat-Anik B-was equipped with 4 experimental 14/12 GHz transponders in addition to 12 commercial radio frequency channels in the 6/4 GHz band used by the earlier Anik A satellites. Spacecraft construction was awarded to RCA Astro-Electronics Division
Proceedings of the Third International Mobile Satellite Conference (IMSC 1993)
Satellite-based mobile communications systems provide voice and data communications to users over a vast geographic area. The users may communicate via mobile or hand-held terminals, which may also provide access to terrestrial cellular communications services. While the first and second International Mobile Satellite Conferences (IMSC) mostly concentrated on technical advances, this Third IMSC also focuses on the increasing worldwide commercial activities in Mobile Satellite Services. Because of the large service areas provided by such systems, it is important to consider political and regulatory issues in addition to technical and user requirements issues. Topics covered include: the direct broadcast of audio programming from satellites; spacecraft technology; regulatory and policy considerations; advanced system concepts and analysis; propagation; and user requirements and applications
Addendum to the Proceedings of the Third International Mobile Satellite Conference (IMSC 1993)
Satellite-based mobile communications systems provide voice and data communications to users over a vast geographic area. The users may communicate via mobile or hand-held terminals, which may also provide access to terrestrial cellular communications services. This Third IMSC focuses on the increasing worldwide commercial activities in Mobile Satellite Services, along with technical advances in the field. Because of the large service areas provided by such systems, it is important to consider political and regulatory issues in addition to technical and user requirements issues. The official Proceedings presented in 11 sessions include: direct broadcast of audio programming from satellites; spacecraft technology; regulatory and policy considerations; hybrid networks for personal and mobile applications; advanced system concepts and analysis; propagation; and mobile terminal technology; and mobile antenna technology
