The First Commercial North American Satellite For Television
Posted by admin under on September 21st, 2011.On the clear day of November 9, 1972 and a Delta 1914 rocket rose into the sky the worlds of satellite and telecommunication technology were revolutionized by the Boeing Anik A1. As the first national synchronous satellite in the world, the Anik A1 was launched to herald a new interconnected era. Groundbreaking technology in the Anik A1 brought the entirety of Canada within immediate communication range. Now people from the Alaskan border and Vancouver to the west, all the way to St. John-s Newfoundland in the east were united under one signal.
In the early 1970-s the Canadian Broadcasting Corporation needed a broadcasting method that could reach the entire country. In addition, they didn-t want to disrupt other countries with their broadcasts. The broadcasts had to not only cover all of Canada, but they had to only cover Canada. To this end, the CBC decided on a single satellite. Using a new shaped beam technology made possible by the special parabolic antenna; the broadcast would only cover Canada. And with the Anik A1-s 12 C-Band transponders all of Canada could receive 12 color television channels. And by placing the satellite in a orbit synchronous to Canada, the broadcast was available 24 hours a day, 7 days a week. Maintained there by the satellite-s rotation, and attitude thrusters. The antenna was kept pointed towards the ground by revolving it counter to the satellite.
In the coming decades satellite television would boom. Dozens of satellites have been launched to cover the Earth from a variety of orbits. These radio signals connected the world as never before. As people grew used to the immediate access to information their desire for interconnectedness exploded. What started with connecting one nation to reliable information grew to our modern world of high speed internet and cell phones.
