GPS satellites circle the earth twice a day in an exact 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 precise position. Your GPS Tracking & Safety tracker receives signals from these satellites, then transmits it’s position to our secure servers over wireless networks. You can then access your data on our web-based software.
