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 layer of the atmosphere is satellites located?
If they are in the atmosphere (low earth orbit), satellites are in the ionosphere. If they are in higher orbits, satellites are considered to be outside the atmosphere.
What is non-geostationary satellite?
A geostationary orbit is an orbit of the Earth that is circular, over the equator, and at the right distance to have a period of 24 hours. A satellite in such an orbit appears to hang motionless, always at the same point in the sky Anything else is a non-geostationary orbit. A satellite in one of those appears to move in the sky, so that if you want to communicate with it, you need a movable dish.
What is the difference between a goes satellite and a poes one?
The GOES are as they say, Geostationary 22,300 miles above the Earth's surface. Gathering information every 15 to 30 minutes. The POES are Polar-Orbiting because the orbit from one polar regoin to the next staying mostly parallel to the meridian line 530 miles above Earth's surface. With the Earth's rotation from west to east the images observe to the west of the last scanned area. The satellites orbit 14.1 times a day putting them at different locations at different times of the day.
Which source of gravity is maintaining all four satellites around the earth?
Satellites of the Earth are held in their orbits by the Earth's gravity. That includes the Moon and all the artificial satellites etc. that are up there.
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 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 type of satellite orbits the earth at 22300 miles above the earth?
A satellite in a geostationary orbit orbits the Earth at around 22,300 miles above the equator. Geostationary satellites appear to be stationary in the sky relative to a fixed point on the Earth's surface, making them ideal for communication and weather monitoring.
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.
Can five satellites cover the whole surface of the earth?
Actually only 3 geostationary satellites are enough to cover the earth.
Is the Hubble telescope a geostationary satellite?
No, the HST orbits at 570 km above Earth (and not 36,000 km as the geostationary satellites do). It flies round Earth (= one orbit) in 97 minutes, the speed is about 28,000 kilometers per hour.
Why does a satellite travel over different parts of the earth?
Because most satellites are not 'geostationary'. A geostationary satellite orbits the Earth at the same speed that the Earth spins on its axis - such as the GPS grid, or TV relay satellites. Most satellites travel faster or slower than the Earth spins.
What is a satellite that stays in one location is called?
A satellite that stays in one location is called a geostationary satellite. These satellites orbit at the same speed and direction as the Earth's rotation, allowing them to remain fixed above a specific point on the planet's surface.
Do all space satellites stay in the thermosphere?
No. That only applies to low Earth orbit. Geostationary satellites orbit beyond it.
How far away are satelites from earth?
Satellites in Low Earth Orbit (LEO) are typically around 160-2,000 kilometers away from the Earth's surface. Geostationary satellites, on the other hand, orbit at an altitude of about 35,786 kilometers above the equator.
Whats the altitude of satellites?
Satellites typically orbit in low Earth orbit (LEO) at altitudes ranging from 160 to 2,000 kilometers, in medium Earth orbit (MEO) around 10,000 kilometers, or in geostationary orbit (GEO) at around 35,786 kilometers above Earth's equator. The altitude depends on the purpose and function of the satellite.
What is the definition of a geostation?
A geostationary orbit is a circular orbit above the Earth's equator at an altitude where the orbital period matches the rotation period of the Earth. This results in the satellite appearing stationary relative to a fixed point on the Earth's surface. Geostationary satellites are commonly used for telecommunications, weather monitoring, and broadcasting.
