Happy 89th Birthday to Sir Arthur C Clarke - Saturday 16 Dec. One of Arthur C. Clarke's most well known inventions is that of the geostationary orbit of satellites. Stationary satellites orbit at altitudes around 22,300 miles. Back in 1945, science-fiction author Arthur C. Clarke imagined communications satellites in stationary orbits where they would travel around the world at the same speed the globe is spinning, making them hang stationary over one spot on Earth's surface. A satellite on its way to stationary orbit is fired to a special equatorial orbit known as a geostationary transfer orbit (GTO). In this highly-elliptical orbit, the satellite swings out 22,300 miles and back in to an altitude of 100 miles above Earth. At an assigned time and place, a "kick motor" attached to the satellite pushes it on out to a circular orbit at 22,300 miles altitude. The stationary-orbit region of space is referred to as the Clarke Belt. That name is in honor of Arthur C. Clarke, of course. Satellites in the Clarke Belt are said to be stationary, geostationary, synchronous or geosynchronous. Happy birthday Sir Arthur Charles Clarke. ____________ Account frozen... | |
