You may have GPS vehicle tracking or be looking at installing GPS vehicle tracking into your company vehicles, but are wondering how they work. How does it keep a live and constant update of where your vehicles are at all times? See the below infographic to see how it works.
The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides critical capabilities to military, civil and commercial users around the world. It is maintained by the United States government and is freely accessible to anyone with a GPS receiver.
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.
