Global Transmission Services (GTS) is s new system for transferring radio signals from the International Space Station (ISS). Starting in the year 2000 it will be tested in the framework of a pilot project. GTS is the first experiment on the new space station and at the same time the possibilities of future commercial uses of the space station as a space-born platform will be investigated. The experiment is being supported by Daimler-Chrysler, Fortis Swiss Watches as well as the German Aerospace Center (DLR) and the European Space Agency (ESA).  \nTwo areas of applications will be investigated during the first phase of the experiment: the worldwide synchronization of watches and the deactivation of stolen vehicles.\n   \nThe new system consists of a computer system and a radio transmitter onboard the ISS. The system is controlled by a new ground control center located directly in Stuttgart. The monitoring and processing of the data take place in the control center on Earth. The data are then sent down to Earth from the transmitter in space.   \n\n\nFor additional information such as the advantages and disadvantages of such a system, click the link below and continue the article.

A radio relay station in orbit above the earth that receives, amplifies and redirects analog and digital signals contained within a carrier frequency. There are three kinds. Geostationary (GEO) satellites are in orbit 22,282 miles above the earth and rotate with the earth, thus appearing stationary. The downlink from GEOs back to earth can be localized into small areas or cover as much as a third of the earth's surface.\n\nLow-earth orbit (LEO) satellites reside no more than 1,000 miles above the earth and revolve around the globe every couple of hours. They are only in view for a few minutes, and multiple LEOs are required to maintain continuous coverage. Medium-earth orbit (MEO) satellites are in the middle, taking about six hours to orbit the earth and in view for a couple of hours.\n\nI hope this helps...\n\nDon

The astroid belt is a region between mars and jupiter that is densly populated with asteroids...scientists believe that this debris are the remains of a planet that existed once.

Sorry, but as far as I can tell, it doesn't exist.\n\nThen again, I know nothing about this area of interest.\nI like enio_giacomini's answer. Go with that.\nThen again, he answered that "magnet" question with "In center," which makes no sense at all.  Whatever. Your call.

The system was developed by the US DOD to simplify accurate navigation.\n\nSatellites were built and launched by US government over several years, and are maintained by them.\n\nSatellites are called NAVSTAR: Navigation System with Time and Ranging. The satellites are positioned in space so that no matter what time it is or where you are on the face of the earth, you should be able to receive signals from at least four satellites. This means that the system is usable anywhere in the world, 24 hrs a day.\n\nWhile the US government owns the satellites, GPS receivers are manufactured and sold by private companies.\n\nyou can get more info from this site:\nhttp://pigseye.kennesaw.edu/~aht5576/Introduction%20to%20GPS.htm

It has to be at the equator.  It is the same reason that geostationary satellites are in orbit over the equator ...they always remain in the same position over the same spot of the Earth.

Sun synchronous orbit - a low earth orbit with a period of two hours.  If at the correct inclination, the satellite will be over the same point on earth at the same time each day.\n\nGeosynchronous orbit - a high orbit with a period of twenty four hours.  At this altitude, the satellite appears to be fixed over the same spot on the equator.\n\nMolnaya orbit - a highly eliptical orbit with a period of twelve hours.  Because the satellite accellerates as it approaches earth and decellerates as it moves away from earth, a satellite in a Molnaya orbit is visibile to polar regions during much of its orbit.  A constellation of three satellites in Molnaya orbit can provide continous visibility to polar regions.

To get a good GPS fix you need to receive signals from several satellites at large angular separations from each other, along the dimension that you're trying to get a fix for.  If all the GPS satellites were in geosynchronous orbits (and therefore in the plane of the equator) there would never be much separation in the north-south direction, so you couldn't get a good latitude fix.  Even the longitude fix would be poor (compared to the present configuration), since the satellites would not have quite as much east-west separation (as seen from the US, for example).  This separation problem exists even in the current system when you try to determine altitude with GPS.  Since all the visible satellites are "up" and none are "down," the altitude determination is a lot less accurate than the determination of latitude or longitude.

The earth has an electromagnetic field that is generated by the earth's core.  The core is a ball of hot liquid iron and nickel spinning around, and the spinning of the metal generates the magnetic field. \nIt surrounds the earth, connecting to the earth at the north and south poles.\nIs that what you mean by "themagenet in earth not found in space?"\nIf that's not what you mean, perhaps you need to reword your question into more understandable English.

Here are some of the questions you need to answer first. Is this a geosynchronous satellite (which means stationary with respect to our view from earth), or a low earth orbiting (LEO) satellite. LEO satellite goes around the earth, typically once every 90-100 minutes. Are the signals powerful enough to do it from your home satellite dish, like that of DirecTV. Do you know the frequency? Do you know where in space it is? There are web sites where you may be able to find the locations of these satellites. Do you have the right equipment, e.g. descrambling signals that may be scrambled. Trying to install a DishTV or DirecTV dish all by yourself is the best exercise to gain some experience in this.

I assume that by the question you mean "What keeps the satellite in orbit?".  It is a balancing act. Gravity is trying to pull the satellite back to Earth. The velocity of the satellite exactly counteracts the pull of gravity and in effect the satellite is falling around the Earth instead of falling to the Earth. \n\nThe speed of the satellite dictates the height of the orbit. There is exactly one height for a satellite that falls around the Earth at exactly the same speed that the Earth rotates--35,786 km. Communication satellite reside at the orbit so that they are always above the area of the globe with which they are used to communicate. \n\n What eventually happens to many satellites is that the friction of the wisps of atmosphere that the satellites transverse tends to slow them down. When that happens, gravity takes control and pulls the satellite back to Earth. Skylab was a good example of that happening.

The main advantage is a somewhat "fixed" location in the sky relative to the Earth, and relative ease in repositioning them into other fixed positions. There are also some advantages to lower orbits. \n\nGPS satellites are NOT geostationary.  They rely on precise on board time signals and precise knowledge of their orbital ephemerii and a large enough "constellation" such that 3 or more are above the horizon and able for your receiver to pick up at any point in time over nearly the whole planet. \n\nWith a sophisticated control system you can make do with several low orbiting satellites.  The advantage with a low orbit is they are cheaper to launch, and can cover a broader range of latitudes ( geostationary orbits MUST orbit over the equator to be geostationary.  That means at higher latitudes they are lower on the horizon.  At some point they become unusuable, so are not suitable for high bandwidth or reliable communications in places like northern Europe or Russia.) Geo satellites would make EXCELLENT relay satellites for constellations of lower orbiting spacecraft, permitting spacecraft to spacecraft communication. Instead of having to relay between several to get around the globe (*) You could go up to a geo, over to another geo and back down to the other low orbiter and get almost anywhere.  You might need two hops between geos in some circumstances.\n\n(*)which would also require a much more densly populated constellation.  Iridium was named that because the original plan was to have as many satellites as the element Iridium has electrons; 77!

The Van Allen belts have very little to do with the earth's core as the other answer suggested. They are believed to be created by the eath's magnetic field interacting with charged particles known as solar wind.  To the extent that we believe the earth's core responsible for creating the earth's magnetic field, I guess the earth's core has some relevance. \n\nAs the solar winds encounter the earth's magnetic field, the radiation becomes trapped within the field. They are repelled from areas of stronger magnetic field where field lines converge. \n\nTwo alternative hypotheses have been proposed. Possibly the Van Allen Belts are lefor over from the aurora, and another argument is that they are the result of volcanic activity of the earth. \n\nSome scientists beleive that they may have a beneficial effect on the planet providing some protection from solar wind, and that weakening them would harm both electronics and living organisms.  there has been a proposal to reduce the charge of the belts, which are a hazard to satellites.

Picture a weight on a string that you spin overhead. The shorter the string, the faster you have to spin the weight to keep it horizontal. It's the same with an orbiting body. A geostationary satellite is placed at the proper orbital radius that its rotational velocity is the same as that of the Earth, so it remains placed over the same spot on the globe as it speeds forward in its orbit.
