Telstar 1 is a defunct communications satellite launched by NASA on July 10, 1962. One of the earliest communications satellites, it was the first satellite to achieve live transmission of broadcast television images between the United States and Europe.
A medium-altitude satellite, Telstar was placed into an elliptical orbit completed once every 2 hours and 37 minutes, inclined at an angle of approximately 45 degrees to the equator, with perigee about 952 km (592 mi) from Earth and apogee about 5,933 km (3,687 mi) from Earth [7]: 3-5 This is in contrast to the 1965 Early Bird Intelsat and ...
Telstar 12 is a K u band satellite with coverage of North America as far west as Cleveland, Ohio, the majority of South America and Europe. Telstar 12 also has the capability to provide intercontinental connectivity including trans-Atlantic to the Mid-East. [3] Eutelsat uses four transponders on the satellite for services between Europe and the ...
Telstar 18V (Telstar 18 Vantage / APStar 5C) is a communication satellite in the Telstar series of the Canadian satellite communications company Telesat. [1] T18V will be equipped with C and Ku-band transponders and operate from 138° East.
The following tables show the frequencies assigned to analog broadcast television channels in various regions of the world, along with the ITU letter designator for the system used. The frequencies shown are for the analog video and audio carriers. The channel itself occupies several megahertz of bandwidth. For example, North American channel 1 ...
Andover Earth Station was one of the first satellite earth stations, located at Andover in the US state of Maine. It was built by AT&T in 1961 to communicate with the Telstar 1 satellite, the first direct relay communications satellite. It provided the first experimental satellite telephone and television service between North America and Europe.
The satellite was designed to provide additional capacity over the North Atlantic region. [3] As of 26 July 2018, Telstar 19V is the heaviest commercial communications satellite ever launched, weighing at 7,076 kg (15,600 lbs) [ 4 ] and surpassing the previous record, set by TerreStar-1 (6,910 kg/15230lbs), launched by Ariane 5ECA on 1 July 2009.
Telstar 18 is designed for a mission life of 13 years. [1] Although fuel use from trim-maneuver thrusters can impact adversely the useful lifespan of a geostationary. The satellite was projected to have enough fuel left to exceed the planned 13 year lifetime. [2] Telstar 18 provides Ku-band voice, video and data services to China, Hawaii, and ...
