There may be as many as 25,000 artificial satellites orbiting Earth, although only around 8,300 are on record and less than 5000 are active. Our planet has only one natural satellite, the Moon.
The main type of satellites are:
1) Geostationary
2) Polar
The name of the second satellite can vary depending on the context. It could be any specific satellite's name, such as "Hubble Space Telescope," "GPS satellite," or "ISS (International Space Station) satellite."
There is an orbit called a geosynchronous orbit (GEO), which is a satellite that travels around the Earth in the Earth's exact speed, so it's always in the same position as the Earth. GEOs are used for communication nowadays, and so ground stations are always in contact with the satellites. That means that your T.V. programs and phone calls are never interrupted! :D
A rocket has three parts all have tanks containing rocket fuel and oxygen. The first part lauches from earth than the secon part brings you closer the the targerted spot in space, The oxygen is needed because spase has no oxygen. Later the second part is released than the top containing the people is left with enough fuel to finish the job.
India has the best spy satellite...... Most people do not know this..........
i dont know. i dont even know what a moral issue is!
Generally unguided rockets used as weapons do not travel as far as missiles, which is the term for guided weapons. Rockets used as fireworks only travel a few hundred feet vertically. Model rockets may reach a height of a mile or more. Rockets used to launch satellites propel the payload above the atmosphere, which expends most of their fuel.
Because satellites lack the geographic constraints of terrestrial systems, they are better suited for long-distance, point-to-multipoint transmissions such as television broadcasts
satellite should be at least 42000Kms from center of earth .As the radius of earth is around 6370Kms ,the height reduces to 35000Kms.
The satellite is used to receive foreign broadcast from other network stations and send it home users
AnswerSatellite communication is a process where a radio signal is transmitted to a satellite above your horizon. That satellite rebroadcasts that signal, on a different frequency, either to a ground station, or to another satellite to be relayed further. It allows communications without any local infrastructure, such as wires, towers, or other equipment. All that is needed is a receiver/transmitter which operates in the correct frequency bands, and which has sufficient power and sensitivity to communicate with a satellite, and the satellites.
Satellite communication allowed the boats in the Volvo Round the World Ocean sailboat race to communicate with the race headquarters, irregardless of where in the world the boats were.
