What is a satellite that stays in one location is called?
No satellites stays exactly still as they could not remain in orbit, but probably you are meaning a geostationary satellite. The orbit of these satellites matches the speed of the earth turning underneath them, so they remain above the same geographical point on the earth.
Where are the satellites?
satellites are located 37,000 km above the earth's equator.
What is meant by a geostationary orbit and what is it used for?
A satellite in a geostationary orbit goes around the earth at the same angular speed that the earth spins on its axis. So to someone on the earth the satellite looks like its not moving because its always at the same location above the earth. These satellites are used for communication purposes. For example, TV stations can reflect their signal off of such a satellite by aiming their transmitter at it. They don't have to change their aim because the satellite is always there. Satellite dish receivers can easily pick up the reflected signal just by aiming the dish antenna at the satellite and again you don't have to change this aim because the satellite is always there. The satellites have to be in a circular orbit above the equator in order for it to be put in a geostationary orbit.
Which atmosphere are satellites found in?
Low earth orbit (LEO) satellites are defined as any artificial object between 160 km and 2000 km altitude. Any satellite from 160 km to 690km are in the Thermosphere.Any satellite in the region between 690km to 10,000 kmaltitude are in the Exosphere.10,000 km is considered the very top of the atmosphere. Any satellites above this altitude is not considered in the atmosphere. Geostationary satellites for example are at an altitude of 35,786 km.
Why do communication and weather satellites always appear at the same place in the sky?
That is because those satellites are in geostationary orbit, which ensures that they stay always above the same spot on the earth's surface. This is possible only if the satellite is placed in orbit at about 22,000 miles above sea level.
Why are satellite dishes in the Northern Hemisphere pointed south and in the Southern Hemisphere there pointed north?
Satellite dishes in the Northern Hemisphere are pointed south to align with geostationary satellites above the equator, while in the Southern Hemisphere, they are pointed north for the same reason. This alignment ensures optimal reception and transmission of satellite signals.
Do satellites go into the mesosphere?
No, satellite orbits are above the mesosphere in the thermosphere, which extends from about 100 to 600 km above the Earth's surface.
How far above the earth is geostationary orbit?
Geostationary satellites are in an orbit that's 22,282 mi (35,786 km) above the surface of the Earth. For more on Geostationary satellite orbits, visit http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx

What is isochronous satellites?
An isochronous satellite is one that orbits the earth in one day. So it orbits the earth as the same speed as the earth rotates. Most satellites that are isochronous are infact geostationary satellites as they also stay in the same position above the earth. However these satellites occupy a very specific orbit above the equator. It is possible to have isochronous satellites that aren't geostationary however getting them to remain in orbit would prove difficult.
What is a geostationary satellite?
Geostationary is the moving orbit in the plane of the equator. Geostationary satellites are 22,300 miles above the Earths surface, and remain stationary at a fixed point. Weather and communication satellites are examples of geostationary satellites.
How do GPS satellite systems orbit?
GPS satellites orbit at 11,000 nautical miles above the Earth
What is the inclination of a satellite to the earths equator?
There is no set inclination of a satellites orbit to the earth's equator. Once in space, the spin of the earth or where it's poles happen to be become irrelevant to the satellite. Many satellites like spy and weather satellites orbit over the two poles (north and south) while communication satellites are placed in orbit directly above the equator at a height that is synchronised with the earth's orbit. This way they stay permanently above the same place on the equator and do not APPEAR to move at all.
What is a geostation satellite?
Geostationary satellites orbit high above the surface of the earth at about 35,000km, directly above the equator. The take the same time to complete one orbit as the earths surface as it rotates meaning it is always above the same point on earth. They are used for TV and telephone signals as well as weather imagery, among other things. A satellites period, the time it takes it to go around the earth, is determined, in part, by its altitude. The further away it is then the longer it will take. You can calculate an altitude where it will take just one day to make an orbit. If this is done then though the satellite orbits the earth it appears to be stationary above one point of the earth. This orbit must be above, or very near to, the equator. For the earth this altitude is approximately 36,000 km (22,000 miles)
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.
Where are the satellites?
satellites are located 37,000 km above the earth's equator.
How are satellite pictures of hurricanes taken?
The National Oceanic and Atmospheric Administration, or NOAA, has Geostationary Operational Satellites 22,300 miles above the Earth's equator. Since the satellite is rotating as fast as the Earth, it can constantly monitor weather systems and capture pictures.
