A 2.5 m parabolic dish antenna for bidirectional satellite Internet access. A very-small-aperture terminal (VSAT) [1] is a two-way satellite ground station with a dish antenna that is smaller than 3.8 meters. The majority of VSAT antennas range from 75 cm to 1.2 m. Bit rates, in most cases, range from 4 kbit/s to 16 Mbit/s.
The Near Earth Network (NEN, formerly GN or Ground Network) provides orbital communications support for near-Earth orbiting customer platforms via various ground stations, operated by NASA and other space agencies. It uses a number of different dishes scattered around the globe.
Parkes Observatory pointing toward the Moon, receiving data from Apollo 11 mission back to Earth. A ground station, Earth station, or Earth terminal is a terrestrial radio station designed for extraplanetary telecommunication with spacecraft (constituting part of the ground segment of the spacecraft system), or reception of radio waves from astronomical radio sources.
After examining many potential sites, the Deutsche Bundespost began construction of the first civil satellite ground station in Germany in 1963. Its construction allowed for satellite communications between Europe and North America for the first time. It was used to transmit, among other things, the Apollo 11 Moon Landing and the 1972 Munich ...
Land earth station, here: aerial for feeder link (uplink). A land earth station (also: land earth radio station) is – according to Article 1.70 of the International Telecommunication Union's (ITU) ITU Radio Regulations (RR) [1] – defined as "An earth station in the fixed-satellite service or, in some cases, in the mobile-satellite service, located at a specified fixed point or within a ...
Aerospace Data Facility-East (ADF-E), also known as Area 58 and formerly known as Defense Communications Electronics Evaluation and Testing Activity (DCEETA), is one of three satellite ground stations operated by the National Reconnaissance Office (NRO) in the continental United States.

The engineers at the Andover Earth Station would have to wait 15 hours for the satellite, travelling at a rate of 5 miles per second (8 km/s), 3,000 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.
