There are nine types of artificial satellites. Here is the list: Astronomical satellites, Biosatellites satellites, Communication satellites, Miniaturized Satellites, Navigational satellites, Reconnaissance satellites, Earth observation satellites, Space stations, and Weather satellites.
Within communicators there are comm relay satellites, and signaling sats. The former receive a signal from the ground and relay it to another location in some way. Some examples are ground station to ground station, like geosynchronous comm birds, ground station to distributed receiver, like direct broadcast satellite, or store-and-forward LEO like Orbcomm. Signaling satellites include navigation satellites like GPS or GLONASS.
Remote sensors have some sort of device for detecting some signal and relaying it to the ground. Some examples are: GOES and TIROS weather satellites, which detect reflected light or other emitted radiation from the atmosphere. Visible spysats, which look at the ground Chandra X-ray Observatory, which images deep space in the X-ray bands THEMIS, which measures the magnetic field that it is in. Signals intelligence sats, which listen for interesting radio. (I differentiate these from com sats in that the person generating the signal isn't trying to get it relayed to another listener.)
Another orthogonal classification system could be made based on the type of orbit the satellite is in. (Orthogonal meaning that any of the above could be in any of the following orbits.)
LEO = low earth orbit, generally less than 12 hours GEO = geostationary earth orbit, a 24 hour equatorial orbit HEO = high earth orbit, more than 12 hours, but not GEO Solar orbit = no longer in earth orbit.
These could be further subclassified, but that's probably enough.
AnswerDifferent satellites are at different heights. They can be anything from hundreds to thousands of miles above us.Answer
There are currently (mid-2012) in excess of 3 000 satellites orbiting Earth, and a handful orbiting other planets.
There are in excess of 26 000 arbitrary pieces of space junk orbiting Earth, and sufficiently large as to justify tracking. (Old rocket casings, results of collisions, and so on.) Unfortunately, there are great numbers of smaller pieces that may still be dangerous, not accounted for. A number of these were created when two different satellites were destroyed in orbit, and a couple of satellites collided.
Each GPS-type system consists of a constellation of about 24 satellites, plus a few spares. Currently GPS, Galileo, Glonass, and a Chinese and (a Japapese system ?) are systems fully or partly in orbit.
Some of the observation satellites look towards space.
It is very difficult to provide secure and jam-proof communications with and from satellites.
This depends on your definition of satellite, meaning if you are referring to man made orbital satellites or natural satellites such as the moon.
Natural satellites can take many forms such as a moon, comet, etc. However man made are generally communication satellites used for relaying information around the world. However some can be used for observation purposes such as satellites containing photo lenses to map or observe the Earth itself.
-> Sputnik - 1 (the first artificial satellite)
-> Osumi (first Japenese)
-> Verena 7
-> Luna 16
-> Aryabhatta 1 (first Indian)
-> Landset 1
-> Terra
-> Kalpana 1
communication navigation monitoring the weather observing the Earth exploring the Solar System
There are more than two types of satellites, but almost basically only two types of orbit, geostationary and polar.
sputnik 1
sputnik 2
There are two types of satellites that are located in a foxed spot over earth the first is reconnaissance satellites for observation of earth and usually used by the military.. The second is earth observation satellites and are intended for environmental monitoring
Mars has two natural satellites. Earth has one.
Meteosat..,syncom3
There are more than two types of kickboxing. The main ones are American and Thai, but in Thai there are several different kinds.
Those satellites be closer to earth than other satellites because then it can find out about earth's weather because if it's close to earth then it get in the way of weather so it can send message about the weather faster than others
There r two different types
Natural satellites such as moons and man made satellites such as a space station.
Two main types of satellites are: Communication(s) Remote Sensing
GPS satellites are used to help us accurately determine the current time and our location. GPS satellites are not directly used to help us predict the weather. Weather satellites use many imaging and sensing technologies to help us predict the weather, but they are not useful in helping us determine our location. They are two different types of satellites with two different purposes. There are many other types of satellites too, such as communication satellites (such as used with Direct TV), space telescopes (such as Hubble) etc.
The main type of satellites are: 1) Geostationary 2) Polar

Yes, GPS and GeoStationary satellites are two different things.
There are billions and billions of satellites they are all diffrent shapes and sizes here is a list of types.NavigationCommunicationExplorationWeatherAstronomyMilitaryReserch
One type of artificial satellite is called a navigation satellite. Two other kinds of artificial satellites are called weather satellites and communications satellites.
geostationary andGeosynchronous satellites
weather and spy satalites
Well two of the four are ,the first is a Scientific satellites . The second is a Applications satellites.
