Andover Earth Station. Andover, Maine.
The site of the Andover Earth Station satellite ground station was selected by AT&T in December 1960. The main factors were the topography of the land and the radio interference signal level. Other factors included a location in the Northeast United States to give a short great circle path to Western Europe, it was located close enough to existing transcontinental radio relay television and telephone routes to facilitate interconnection. In addition, the site had to be large enough to accommodate an antenna structure and control building, and provide for expansion, if necessary. Telstar was launched on July 10, 1962 from the Cape Canaveral Air Force Station and went into orbit at 4:46 a.m.. The engineers at the Andover Earth Station would have to wait 15 hours for the satellite, traveling at a rate of 5 miles per second (8 km/s), 3000 miles (4,800 km) above the earth to reach within their “view”. The engineers successfully sent a signal to Telstar, which amplified it 10 billion times and relayed it back to Andover.
