On April 6, 1965, Intelsat ’ s first satellite, the Intelsat I ( nicknamed Early Bird ), was placed in geostationary orbit above the Atlantic Ocean by a Delta D rocket.

* 1964 – The opening ceremony at The 1964 Summer Olympics in Tokyo, Japan, is broadcast live in the first Olympic telecast relayed by geostationary communication satellite.

Also, it is trivial to transmit a carrier radio signal to a geostationary satellite and thus interfere with the legitimate uses of the satellite's transponder.

Artsutanov suggested using a geostationary satellite as the base from which to deploy the structure downward.

By using a counterweight, a cable would be lowered from geostationary orbit to the surface of Earth, while the counterweight was extended from the satellite away from Earth, keeping the cable constantly over the same spot on the surface of the Earth.

This " orbital tower " is a giant structure rising from the ground and linking with a satellite in geostationary orbit at the height of approximately 36, 000 kilometers ( approx.

** NASA launches Syncom 2, the world's first geostationary ( synchronous ) satellite.

In 1960 TIROS-1, NOAA's first owned and operated geostationary satellite was launched.

A satellite in a geostationary orbit appears stationary, always at the same point in the sky, to ground observers.

Communications satellites are often given geostationary orbits, or close to geostationary, so that the satellite antennas that communicate with them do not have to move, but can be pointed permanently at the fixed location in the sky where the satellite appears.

In the special case of a geostationary orbit, the ground track of a satellite is a single point on the equator.

If one could see a satellite in geostationary orbit, it would appear to hover at the same point in the sky, i. e., not exhibit diurnal motion, while the Sun, Moon, and stars would traverse the heavens behind it.

The first communications satellite placed in a geostationary orbit was Syncom 3.

Communications satellites and weather satellites are often given geostationary orbits, so that the satellite antennas that communicate with them do not have to move to track them, but can be pointed permanently at the position in the sky where they stay.

A geostationary transfer orbit is used to move a satellite from low Earth orbit ( LEO ) into a geostationary orbit.

) The first satellite placed into a geostationary orbit was the Syncom-3, launched by a Delta-D rocket in 1964.

A statite, a hypothetical satellite that uses a solar sail to modify its orbit, could theoretically hold itself in a geostationary " orbit " with different altitude and / or inclination from the " traditional " equatorial geostationary orbit.

Satellites in geostationary orbits are far enough away from Earth that communication latency becomes significant — about a quarter of a second for a trip from one ground-based transmitter to the satellite and back to another ground-based transmitter ; close to half a second for a round-trip communication from one Earth station to another and then back to the first.

For example, for ground stations at latitudes of φ = ± 45 ° on the same meridian as the satellite, the time taken for a signal to pass from Earth to the satellite and back again can be computed using the cosine rule, given the geostationary orbital radius r ( derived below ), the Earth's radius R and the speed of light c, as

Maneuvering into a large circular orbit, e. g. a geostationary orbit, requires a larger delta-v than an escape orbit, although the latter implies getting arbitrarily far away and having more energy than needed for the orbital speed of the circular orbit.

The transfer to a graveyard orbit above geostationary orbit requires the same amount of fuel that a satellite needs for approximately three months of stationkeeping.

In order to obtain a license to provide telecommunications services in the United States, the Federal Communications Commission ( FCC ) requires all geostationary satellites launched after March 18, 2002, to commit to moving to a graveyard orbit at the end of their operational life.

Applying a delta-v at the LEO of only 0. 78 km / s more ( 3. 20-2. 42 ) would give the rocket the escape speed, while at the geostationary orbit a delta-v of 1. 46 km / s is needed for reaching the escape speed of this circular orbit.

A combination of lunar gravity, solar gravity, and the flattening of the Earth at its poles causes a precession motion of the orbital plane of any geostationary object, with a period of about 53 years and an initial inclination gradient of about 0. 85 degrees per year, achieving a maximum inclination of 15 degrees after 26. 5 years.

At latitudes above about 81 °, geostationary satellites are below the horizon and cannot be seen at all.

A synchronous orbit about the Earth that is circular and lies in the equatorial plane is called a geostationary orbit.

While a majority of artificial satellites are placed in LEO, making one complete revolution around the Earth in about 90 minutes, many communication satellites require geostationary orbits, and move at the same angular velocity as the Earth.

Broadband applications benefit from low-latency communications, so LEO satellite constellations provide an advantage over a geostationary satellite, where minimum theoretical latency is about 125 milliseconds, compared to 1 – 4 milliseconds for a LEO satellite.

It wasn't until 1985 that Australia's first geostationary communications satellite was operational ; by late 1990 it had debts of about $ 400 million.

The use of EGNOS on the ground, especially in urban areas, is limited due to relatively low elevation of geostationary satellites: about 30 ° above horizon in central Europe and much less in the North of Europe.

At about 3: 55 p. m., the IUS fired the first of two burns that would put TDRS-G into its proper, 22, 000-mile-high geostationary orbit above the central Pacific Ocean at 178 degrees West longitude.

It covered about 40 % of the Earth's surface, from its geostationary orbit.

The ASO is analogous to a geostationary orbit ( GSO ) about Earth.

The group listed three missions for the initial Saturn vehicle: unmanned lunar and deep space missions with an escape payload of about 4, 500 kg ; 2, 250 kg payloads to geostationary orbit ; and manned spacecraft missions in low orbits, such as Dyna-Soar.

* There were similar concerns about the allocation of the geostationary orbit ( parking spots in space ) for satellites.

On November 9, 1972, Canada's first geostationary satellite serving the continent, Anik A1, was launched by Telesat Canada, with the United States following suit with the launch of Westar 1 by Western Union on April 13, 1974.

* Communications satellites are typically 1. 337 light-milliseconds ( low earth orbit ) to 119. 4 light-milliseconds ( geostationary orbit ) from the surface of the Earth.

A Soyuz rocket with a 1. 7 tonnes to geostationary transfer orbit ( GTO ) performance from Baikonur, will increase its payload potential to 2. 8 tonnes from the Guiana launch site.

In late 1993 NSAB acquired Marco Polo 1, a Hughes 376 geostationary communications satellite, from British Sky Broadcasting.

Bell TV broadcasts from four geostationary satellites: Nimiq 1, 2, 3 and 4iR.

Westar 1 was America's first domestic and commercially launched geostationary communications satellite, launched by Western Union and NASA on April 13, 1974.

" A single SkyTower platform can provide over 1, 000 times the fixed broadband local access capacity of a geostationary satellite using the same frequency band, on a bytes per second per square mile basis.
