tell me about GEO satellites?

Answer 1

wikipedia is you friend

Answer 2

Geosynchronous Earth Orbiting (GEO) satellites are in orbit above the equator of the Earth in a high enough orbit such that the orbital speed is the same as the Earth's rotation (24,000 miles up) so they stay above the same spot on the Earth's equator.

All your dish-TV, cell phone and GPS satellites are located here. Its prime real estate.

Now, if you had a really big satellite in GEO and had a rope long enough and strong enough, you could lower it to the earth and lift stuff up! This concept is called the Space elevator, and its not as preposterous as it sounds; we have material strong enough to use one on the Moon.

Answer 3

You have had several answers that mentioned the orbit altitude is 42,164 km (26,200 miles), and the rotational speed of the satellite matches that of earth, so the satellite remains over the same location at the equator.

A Geosynchronous orbit can only occur at 42,164 km (26,200 miles) for the earths gravitational field. Any lower and the satellite speed is slower, and any higher and the satellite speed is faster, which means the satellite would move in relation to it's location over the earth.

Answer 4

(Geostationary Earth Orbit) A communications satellite in orbit 22,282 miles above the equator. At this orbit, it travels at the same speed as the earth's rotation, thus appearing stationary. GEOs are excellent for TV broadcasting, but produce distracting, half-second delays in interactive voice conversations, because of the long round trip from earth and back. LEOs and MEOs, which are closer to the earth, are being deployed for interactive services. LEO (low earth orbit) and MEO (medium earth orbit).

GEOs Appear Stationary
GEOs rotate at earth speed and thus appear stationary. LEOs and MEOs are closer to earth and revolve around the planet.

Answer 5

Geo satellites travel at earth's rotation speed and will rotate along with the earth's rotation. For example, a satellite placed on America will be focused on America for all 24 hours.

Polar Satellites do not travel along with earth and will not focus on one region. A polar satellite focussing america at noon will focus on India during 10 pm.

Answer 6

Geosynchronous Earth Orbit is when a satellite obits the Earth over the same point on the equator. This occurs when the period of orbit is 24 hours. The altitude is about 22,500 miles.
