What is a non Geo stationary satellite?
Non Geo stationary satellite is that satellite which has different angular velocity from earth and not placed on the height of 36000 Km from the earth. If you use Geo stationary satellite than only 3 satellites are enough to cover whole world. most of satellite are geostationary and they are(most of them) active satellites too.
Who invented artificial satellite?
Arthur C Clarke the science fiction author of 2001 a Space Oddysey wrote a speculative scientific paper published in the UK Wireless World magazine in 1945. He proposed a geostationary satellite which could be used as a fixed radio relay station in space. The editors thought he was crazy but a brave sub editor went ahead and published it to his credit.
What orbit would allow a satellite to see all parts of the globe?
A geostationary orbit would allow a satellite to see all parts of the globe as it orbits the Earth at the same speed that the Earth rotates. This means the satellite remains fixed above the same point on the equator, providing continuous coverage of that area.
Is sputnik 1 a probe or satellite?
Sputnik 1 was the world's first artificial satellite. It was launched by the Soviet Union in 1957 and played a significant role in the space race. It transmitted radio signals back to Earth and orbited the planet for three months before its battery ran out.
What do you mean by satellite?
A satellite is an object that orbits around another object. A satellite can either be natural, like a moon, or man-made like the satellites that help bring Internet and television from around the world.
How does the satellite transmit tv programs inspite of the fact that it moves all the time?
Answer: A geostationary satellite is any satellite which is placed in a geostationary orbit. Satellites in geostationary orbit maintain a constant position relative to the surface of the earth. Geostationary satellites do this by orbiting the earth at approximately 22,300 miles above the equator. At this altitude, the speed of a satellite's rotation around the world is identical to the rotational speed of the world itself. While the satellite is actually moving; but moving at the same speed as the rotational speed of the world itself, it is always appears in the same azimuthal (angle); latitudinal and longitudinal position of the sky over the equator. Being geostationary allows an earth receiving & transmitting station to maintain bidirectional communications with satellites without the need of having to always reposition the earth based "dish" like antenna. A practical example is one's home whose television is connected to a unidirectional (receives only) dish antenna. If the satellite that the dish antenna is aimed at was not geostationary, people would lose the satellite's signal as soon as it deviated one degree from its position. In general, all data, audio & video satellites are launched into a geostationary orbit.
When was satellite radio invented?
The idea of sending a satellite to geostationary orbit was first published in 1928 by Herman Potocnik, however this was widely overlooked. Science Fiction writer Arthur C. Clarke is often credited for the proposal of creating geostationary communication satellites after his article "Extra-Terrestial Relays--Can Rocket Stations Give Worldwide Radio Coverage?" was published in the magazine Wireless World in 1945. However, it wasn't until 1964 that Syncom 3, the first geostationary satellite, was actually launched. Since then, many satellites have been sent to geostationary orbit. Most communication and broadcast satellites use a geostationary orbit because it is ideal for sending signals to a specific region.

Why is geostationary important?
A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 kilometers (22,300 miles) directly over the equator, that revolves in the same direction the earth rotates (west to east). At this altitude, one orbit takes 24 hours, the same length of time as the earth requires to rotate once on its axis. The term geostationary comes from the fact that such a satellite appears nearly stationary in the sky as seen by a ground-based observer. In other words a satellite that orbits a specific part of the earth while the earth is rotating so it looks like the satellite doesn't move. For example if you put a satellite over over the geographic US it will stay over the US and turn with the earth around the axis without ever loosing site of the US.
What are the main features of geostationary orbits?
In the geostationary orbits, the angular speed of the satellite will be the same as that of the earth. Hence the satellite will be at the same location above our head all the time, if it is installed so. If three such geostationary satellites each above Atlantic, Pacific and Indian Ocean inclined at angle 120 degree from one another are installed, then the whole world will be connected round the clock from nook and corner.
Why is a satellite necassary to send tv signals around the world?
Television channels used to only be available to the homes were the cable wires were placed. Satellite allowed television channels from all over the globe become available to every household.
What was the satellite TV network?
Orbita (1967) - first national network of satellite tv which was created in Soviet Union Anik 1 (1972) - first domestic north American satellite to carry television in Canada ATS-6 (1974) - world's first experimental educational and direct broadcast satellite Ekran (1976) - the first soviet geostationary satellite to carry direct-to-home television
What do broadcasting stations use to send their signals around the world?
Broadcasting stations use television satellites to send their signals around the world.
What satellite helps to map windspeed?
The series of NASA satellites called GOES (Geostationary Operational Environmental Satellites) monitor storms and other conditions, especially in the world's oceans.But a specialized satellite, that mapped geographical wind speeds from 1999 to 2009, was the QuikSCAT satellite. It replaced an original wind observation device (NSCAT) that functioned aboard a Japanese satellite from 1996 to 1997.
Did eygptians watch TV?
Egyptians, like the rest of the world, (Mexicans, Italians, Japanese, etc) receive over the air TV signals, satellite TV signals, and cable TV signals. So the answer to this astoundingly stupid question is YES!
What are the main differences between geostationary orbit and polar orbit?
A polar orbit is an Orbit in which a Satellite passes above or nearly above both of the Geographical poles of the body (usually a planet such as the Earth, but possibly another body such as the Sun being orbited on each revolution. It therefore has an Inclination of (or very close to) 90 degrees to the Equator. Except in the special case of a polar Geosynchronous orbit, a satellite in a polar orbit will pass over the equator at a different Longitude on each of its orbits.A geostationary orbit (GEO) is a circular orbit directly above the Earth's Equator From the ground, a geostationary object appears motionless in the sky and is therefore the Orbit of most interest to operators of Communication Satellites. Their orbital periods (time taken to revolve around earth) is exactly the same as the planet's (such as Earth's) rotational period. The Geosynchronous orbit is approximately 36,000 km above Earth's surface.geostionary satellites are positioned at an exact height above the earth, at this height they orbit the earth at the same speed at which the earth rotates on its axis whereas polar satellites have a much lower orbit, orbiting the earth quite quickly, scanning different areas of the earth at fairly infrequent periods.
