Overview
"In 1963 Hughes Aircraft and NASA achieved geosynchronous orbit (known as GEO today) with the successful launch of the Syncom satellite. The satellite was placed in an orbit of approximately 36,210 km, a distance that allowed it to remain stationary over a given point on Earth's surface."[1]
