How does Global Positioning System GPS work?

Answer 1

SYSTEMATICALLY

Answer 2

A GPS works by satellites that are located in outer space. These satellites are connected with cameras that show the whole earth. You GPS and the satellites systems are working together to provide maps for you.

Answer 3

In GPS (global positioning system), special satellites orbiting the earth transmit radio signals. A GPS receiver on earth receives signals from several GPS satellites and can figure out its location from the signals. The satellites know their own positions and transmit this information as part of the signals. They also have precise atomic clocks and transmit timing information as part of the signals. The receiver can estimate the distance to each satellite from the timing information. It can then figure out its own location using the known positions of the satellites.

Answer 4

GPS stands for "Global Positioning Satellites" there are currently 32 of these in space. These satellites send a constant signal to earth, if you use a satellite receiver such as a common hand held, like will say Tom Tom it receives these signals. You have to have line of sight to at least three of these satellites to get a position. The receiver takes the signal from all available satellites and using triangulation pinpoints the receiver's location. The more signals a receiver can use the more accurate the position.

Answer 5

To put it as simple as possible, a GPS uses the principle of triangulation to calculate it's location. Orbiting satellites transmit a precise time signal to the GPS unit. Calculating the difference in time from when the signal was sent to when it was received (knowing that it was transmitted at the speed of light), it can determine a distance from the satellite. Imagine this distance plotted as a sphere coming out from the satellite. It then calculates this data from at least two other satellites. Naturally, the point at which these three spheres intersect, the only point at which the appropriate distances can be achieved from each satellite, is the position of the GPS receiver. In an enhanced system, called WAAS (Wide Area Augmentation System) that is used in most modern-day receivers, additional data is supplied from various land based beacons that allows for an even more accurate location fix.

Answer 6

Theb GPs receives signals from satellites.
