Orbits[ change change source ] A satellite in a geostationary orbit. A synonym for disposal orbit. Polar-orbiting satellites orbit Earth in a north-south direction from pole to pole, so as Earth spins underneath, these satellites scan the entire globe strip by strip.

Currently there are approximately 1, [19] artificial satellites orbiting the Earth. Pseudo-orbit classifications[ edit ] Horseshoe orbit: Polar sun synchronous orbit: A geostationary satellite orbits Earth from west to east over the equator.

Navigation satellites were developed primarily to satisfy the need for a navigation system that nuclear submarines could use to update their inertial navigation system. Transit satellites provided a constant signal by which aircraft and ships could determine their positions with great accuracy.

Artificial Satellites

Low orbits work well for satellites that take pictures of the Earth. Orbits[ change change source ] A satellite in a geostationary orbit.

Nuclear power sources Radioisotope thermoelectric generator have also been used in several successful satellite programs including the Nimbus program — Eccentricity classifications[ edit ] Circular orbit: Satellite Facts for Kids Check out these fun Satellite facts for kids.

Nuclear power sources Radioisotope thermoelectric generator have also been used in several successful satellite programs including the Nimbus program — To move this way, the satellite must be straight above the equatorand 35, kilometers 22, miles above the ground.

An elliptic orbit where the perigee is at the altitude of a Low Earth orbit LEO and the apogee at the altitude of a geosynchronous orbit. The limitations of the Transit system spurred the next advance in satellite navigation: An orbit which combines altitude and inclination in such a way that the satellite passes over any given point of the planets' surface at the same local solar time.

Besides this eccentricity an orbit of a satellite about the earth is characterized by its plane with respect to the earth. Artificial satellites can have a range of missions, including scientific research, weather observation, military support, navigation, Earth imaging, and communications.

The orbital characteristics of Earth's Moon.

Artificial Satellites

There are estimated to be more than 8, pieces of space junk; dead satellites or pieces of debris going around the Earth as well. The list includes the European Space Agencya multi-national state organization, but does not include private consortiums.

What Are Satellites Used For?

Receiving uplinked radio signals from earth satellite transmission stations antennas. This means a satellite dish a type of antenna must be always moving in order to send or receive communications with that satellite. End of life[ edit ] When satellites reach the end of their mission this normally occurs within 3 or 4 years after launchsatellite operators have the option of de-orbiting the satellite, leaving the satellite in its current orbit or moving the satellite to a graveyard orbit.

It began operations is with 10 satellites, succeeding an experimental system that became operational inand is planned to utilize 35 satellites when completed in.

Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as Earth's Moon. In the Soviet Union launched the world's first artificial satellite, Sputnik 1.

Since then, about 8, satellites from more than 40 countries have been launched. satellite, artificial Artificial object placed in orbit around the Earth or other celestial body. Satellites can perform many tasks, including sending back data or pictures to the Earth.

Satellites, Non-Governmental High Resolution

Satellites. This is a list of all Indian (wholly or partially owned, wholly or partially designed and/or manufactured) satellites, both operated by the Indian government (ISRO, Indian defence forces, other government agencies) or private (educational and research) entities.

Collection of information about natural resources of earth Artificial satellites are also used for collecting information about natural resources of earth like oil wells, underground water, minerals, natural gas and coal deposits etc.

A satellite is an artificial object that is deliberately sent into orbit in space, usually in order to send, receive or bounce back information to different areas of Earth. Artificial satellites are man-made satellites, they differ to natural satellites such as the Moon which orbits Earth and Earth itself which orbits the Sun.
