There are two special locations for satellites:
* geostationary orbits
* polar orbits
For satellite communication, it is very convenient if one can align fixed ground antenna to point at the satellite.
The only way to get a satellite to stay exactly in front of a fixed ground antenna is to put it in geostationary orbit -- an altitude of 35,786 km above sea level above the equator.
Other than geostationary orbit, there are a few other orbits that hold a satellite approximately in front of a fixed ground antenna for several hours -- the Molniya orbit and the Tundra orbit.
Satellites designed to take photos of Earth (weather satellites, spy satellites, etc.) are typically in a polar orbit.
Sooner or later, a satellite in polar orbit will end up directly overhead any given point on Earth.
Typically these satellites are in an orbit very roughly 1000 km above sea level (roughly 100 minute orbit), because higher orbits are more expensive, and orbits less than a few hundred km rapidly decay from air friction.

How does satellite technology use a transponder?
Satellite technology uses a transponder to receive sings and then transfer them to satellites in other locations. They are used for purposes of space satellites and GPS.
What is the acronym for the system of US Department of Defense satellites which are used to establish exact locations on Earth?
GPS
What types of artificial satellites are there?
There are several types of artificial satellites, including communication satellites for transmitting signals between locations, weather satellites for monitoring and predicting weather patterns, navigation satellites for providing accurate positioning information, and observation satellites for taking images of Earth's surface for various purposes. Additionally, there are also scientific research satellites for conducting experiments and gathering data in outer space.
What does ASAT stand for?
An ASAT is an anti-satellite weapon, a space weapon designed to incapacitate or destroy satellites for strategic military purposes.
How were satellites used in war?
If you're thinkiing of WW2, there were no such things as satellites at that time. In fact the first artificial satellite of the earth was launched by the Russians around 1957/58!
What are the names of the earths satellites?
Earth has only one natural satellite and that is the moon. There are however over 13,000 artificial satellites, and the most widely recognized is the International Space Station (ISS). There are lots of programs and websites where you can see the names and locations of all these satellites, there are just too many to list here - search WIKIPEDIA for List of Earth observation satellites.
