Canadian Satellite Communications Inc. It's a satellite that orbits the earth at a height of approximately 36,000 km., moving in exact synchronization with the earth's rotation. This makes the satellite appear stationary to an observer on earth. At this location, the centrifugal force that wants to push the satellite off into space is directly balanced by the pull of gravity.
Many countries have their own satellites.
Canada's are called Anik E1 and E2. Cancom uses the Aniks as well as the U.S. satellites GE III and Telstar 5.
