Do You Really Know How GPS Tracking Systems Work?

When many people think of a GPS tracking system they're really thinking about GPS receivers. These are the basis of navigational aids that receive signals from satellites in the Global Positioning System and use trilateration to determine the unit's location. GPS tracking systems utilize a separate connection to the GPS receiver to acquire its data. Some GPS-capable devices don't provide information wirelessly, but historical location data can be downloaded when the device is connected to a network.


Do you have to subscribe to gps service?

The signals that a GPS receiver or Sat Nav system uses to calculate its position are broadcast freely and globally by the GPS satellites orbiting earth 20,000Kms away. As there is no way for the GPS satellites to know who or what is receiving or using the signals that they broadcast, it would be impossible to charge people for their use. Much like free to air TV or radio. Subsequently, the GPS service is free. The hardware required to use it however will cost you.
