iSpy in the iSkye

Here is the spy-bird view of our home via GoogleEarth. Amazing.
It was Sir Arthur C. Clarke’s proposal of geostationary satellite communications that led to the development of this technology. Like most individuals who think outside the box, his idea wasn’t taken seriously when it was published in Wireless World magazine in 1945. Obviously he got the last laugh on April 6, 1965 when Intelsat I Early Bird became the first commercial geostationary communication satellite. Check out NASA J-Track 3D to view a database of over 900 satellites.
What exactly is geostationary orbit? OK, you asked...A satellite in an equatorial circular orbit at a distance of approximately 42,164 km from the center of the Earth, i.e., approximately 35,787 km (22,237 miles) above mean sea level has a period equal to the Earth's rotation on its axis (Sidereal Day=23h56m) and would remain geostationary over the same point on the Earth's equator. Got it? It is just easier to appreciate and enjoy the technology.
