There are currently 32 satellites, a gps system needs to receive a signal from at least 3 of them to function. Older systems only used 3-4 but new systems can use up to all 32 the more satellites that a system uses....the greater the accuracy.

What kind of a signal does a GPS give off?
Your hand-held GPS is a receiver. It listens to signals fromGPS satellites, and doesn't "give off" any signal of its own.
How many satellites do you need for a GPS to find your position on earth?
There are 24 satellites in the United States GPS system that are active. There are 6 more that are "asleep" and saving power until they are activated to replace one of the 24 satellites that has to be taken off line for maintenance, damage, and so forth.The Russians also have roughly that number of satellites in their GLONASS system.Europe is deploying satellites in its Galileo positioning system.Japan has or will launch its first satellite in its QTZZ positiong system.There are also about 4 satellites in WAAS, the Wide Area Augmentation System that makes GPS more accurate. Europe's version of this is EGNOS, or European Geostationary Overlay Service. It has 4 or 5 satellites.
Does a gps give off radiation?
No. GPS receivers do not transmit or radiate anything. They just listen to radio wave radiation from the constellation of GPS satellites that orbit about 11,000 miles above the Earth.
Can GPS work in Barbados?
Yes, GPS can work in Barbados. It is a global positioning system that uses satellites to provide accurate location information. As long as you have a GPS-enabled device and you are within range of satellite signals, you should be able to use GPS in Barbados or any other location worldwide.
How can you be invisible from GPS signals?
It is difficult to be completely invisible from GPS signals, as it is a passive technology that relies on receiving signals from satellites. However, you can reduce the accuracy of your GPS location by turning off GPS services on your device or using a GPS jamming device. Keep in mind that interfering with GPS signals may be illegal in some jurisdictions.

Can the GPS system be turned off on an ipod touch?
There is no GPS system on the iPod Touch. The iPod Touch does not have Global Positioning System capabilities at all. Therefore, there is no need to turn off what is not there.
How much would GPS be off if time corrections due to speed and gravitational pull of earth were not made?
Time in the GPS satellites run 1/3 of a billionth of a second faster than time on Earth. This could potentially make the GPS systems off by 6 miles.
Can GPS work in Barbados?
Yes, GPS can work in Barbados. It is a global positioning system that uses satellites to provide accurate location information. As long as you have a GPS-enabled device and you are within range of satellite signals, you should be able to use GPS in Barbados or any other location worldwide.
Can you give me a name for gps that can work underground or in pipeline?
None of them do, as the can't pick up radio waves from the satellites down there. You'd need either an INS or a system using specially deployed beacons to pull that off.
How do you delete addresses off the GPS system?

How does a GPS work and where can I get one?
Conventional GPS operation uses radio signals from satellites. In very poor signal conditions, for example in a city, these signals may suffer multipath where signals bounce confusingly off buildings, or be weakened by passing through walls or tree cover_ An A-GPS system can address these problems in several ways, using an assistance server or other data from a network.
Why are gps data not enough to confirm that the earth's surface has been moving for many years?
because scientificly , the Earth is just to much for the GPS to keep track of. Also the GPS runs of off satellites and different types of plates in the ground so it cannot tell if the Earth's bin moving for many of the years.
How does GPS know where you are?
A GPS receiver determines its location by analyzing signals it receives from GPS satellites orbiting around Earth. Signals from satellites that are farther away take longer to reach the GPS receiver. Distances to several satellites are calculated based on the amount of time their signals took to reach the receiver. After determining its distance from at least three satellites, the GPS receiver can calculate its own position using triangulation. (Any location can be identified using distances from three other know locations.)
