How it works
GPS satellites circle the earth
twice a day in a very precise orbit and transmit signal information to
earth. GPS receivers take this information and use triangulation to
calculate the user's exact location. Essentially, the GPS receiver
compares the time a signal was transmitted by a satellite with the time
it was received. The time difference tells the GPS receiver how far away
the satellite is. Now, with distance measurements from a few more
satellites, the receiver can determine the user's position and display
it on the unit's electronic map.
