They take 24 hours to orbit earth so they will always be in the same place in the sky. This makes it easier for setting up satellite dishes for example, since they have to be pointed toward the satellite.
The most likely factor that would cause a communications satellite orbiting Earth to return to Earth from its orbit would be atmospheric drag. As the satellite moves through the Earth's atmosphere, it experiences friction with air molecules which can slow it down and cause its orbit to decay, eventually leading to re-entry into Earth's atmosphere.
It is a little strange that things in higher orbits actually travel more slowly than things in lower orbits. The Space Shuttle and the International Space Station both orbit in about 90 minutes, while the Moon - 250,000 miles away - take a whole month to orbit the earth. There is one kind of orbit that has a special name and a special purpose. A satellite that orbits at 22,300 miles high will orbit the Earth in 24 hours. You might notice that the Earth revolves around its axis in 24 hours. So a satellite at that altitude orbits the Earth at the same rate that the Earth turns, which means that the satellite is moving just as fast as the Earth does. So the satellite appears to stand still in the sky! We call this a geo-synchronous orbit. Geo, for Earth; synchronous, for "equal time". This is an especially handy orbit for things like communications satellites, which "hover" over the same spot on the equator.
If a satellite is in geosynchronous orbit, it will take the satellite 24 hours, a day, to orbit the Earth once. This is so because geosynchronous orbit is when a satellite orbit the Earth at such a time, that is is over the Earth at all times.
The period of a satellite is the time it takes for the satellite to complete one orbit around its parent body, such as a planet or a star. It is typically measured in hours, days, or years depending on the size and speed of the satellite's orbit. The period is determined by the satellite's orbital velocity and the mass of the parent body it is orbiting.
A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period.
The most likely factor that would cause a communications satellite orbiting Earth to return to Earth from its orbit would be atmospheric drag. As the satellite moves through the Earth's atmosphere, it experiences friction with air molecules which can slow it down and cause its orbit to decay, eventually leading to re-entry into Earth's atmosphere.
Satellite phones work by connecting directly to a communications satellite in orbit, which then routes the call to a standard phone network. Because the satellites are in orbit the phone can work anywhere on earth.

The time it takes for a satellite to complete one full orbit around the Earth, known as its orbital period, can vary depending on the altitude of the satellite. On average, a satellite in low Earth orbit (LEO) typically takes about 90 minutes to complete one orbit, while a geostationary satellite orbits the Earth every 24 hours.
A Geostationary orbit - it means that the satellite will always stay above the same point on Earth. Hope that helps
That depends on the altitude. Low altitude satellites, about 140 miles up, take about 90 minutes to orbit. Communications satellites 23,000 miles up take 24 hours. The higher the orbit, the longer it takes.
Geo
You can use Kepler's Third Law to calculate this.
A satellite in orbit around Earth acts as a communications relay, collects data for research, monitors weather patterns, and provides navigation services.
As a noun: The rocket placed the satellite into a high Earth orbit. As a verb: The satellite had to travel very fast to orbit the Earth.
The altitude of the satellite is critical depending on the purpose of the satellite. Low-Earth Orbit (LEO) satellites are fairly close to the Earth, and is good for photographic reconnaissance; it's a lot easier to get a good photo from 140 miles up as opposed to 23,000 miles up. The LEO satellite passes quickly over the surface, and isn't visible above the horizon for more than a few minutes per orbit, so LEO satellites work poorly for communications purposes. Geo-synchronous Earth Orbit (GEO) satellites orbit the Earth at an altitude of about 23,000 miles, and orbit the Earth in 24 hours - meaning, they orbit the Earth in the same time that it takes for the Earth to spin once. So a GEO satellite that's over the equator will appear to be in a fixed position in the sky, and doesn't appear to move. These are excellent for ground communications and relay purposes, because the ground antenna doesn't need to move; it's always pointed at the satellite. Polar orbit satellites will pass over every point on the Earth; the satellite is going around the world while the Earth spins beneath it.
umm if my calculations are correct the period of a low earth orbit (LEO) is approximately 40000000000069 years. as extrapolated from Kepler's equation.
