GPS works like a distance measuring device using a laser.... the only difference is it uses time intervals. GPS consist of some components such as the satellite receiver , atomic clocks, power supply and etc.
Lets start from GPS satellite... in these satellites they have we so called the atomic clocks. These clocks gives time and being sent by the transmitter in the satellite in all direction and within this direction the GPS receiver we have onland or on seas can detect this and try to calculate at what time it received the signal. This calculation will give you the bearing(direction) and distance travelled by this signal, with 3 satellites it can give you the accurate position of your receiver by plotting these distances and directions(cross-bearings).
The verizon GPS phones work by getting a GPS signal to pinpoint your location. You can use Maps if you have an iPhone or Android smartphone, which is perfect.
i think because the gps doesnt work well because of the sun
No, GPS doesn't work outside the US.
GPS on phones are very accurate. They work just as good as a regular car GPS because they both work off of a satelite that feeds them information.
A GPS holder is not a necessity. The GPS will work just fine without it. Having a GPS holder will, however help you protect the GPS and prolong its useful life.
A GPS will work anywhere it can receive adequate signals, and assuming you have a decent antenna, any GPS will work in an airplane. However, a GPS that is not programmed for aviation uses will not be nearly as useful as one that is. A car GPS or trekking GPS may give you lat/long readouts, which may be of some use in an aircraft, but they will be of limited use for a flight.
yes , GPS is fully equipped to work for people walking on foot.
That depends if you have the maps downloaded, if so then it will work fine. The terrain should not and will not affect the GPS unless you are working with a GPS that communicates via Wi-Fi.
GPS is electronic because it needs electricity to make it work.
A GPS (Global Positioning System) device purchased anywhere will work anywhere.
Portable GPS units work anywhere, in any car or handheld. A factory installed GPS unit generally cannot be moved to another car.
The Navigon GPS works internationally, like most other gps systems. They are run through satellites, which would not cease to work overseas in Europe or Asia.
