- A GPS antenna is tethered to the unit with a lead wire (typically 10-15 feet).
- The GPS antenna collects the GPS data and feeds it to the unit.
- The unit does some processing of events and speeds.
- Additionally, the GPS vehicle tracking unit has a wireless modem inside, similar to ones found in cell phones.
- This modem is used to communicate with Global Tracking’s systems.
- The GPS data is sent directly from the vehicle’s unit to our servers.
- where we process the information for the user.
A GPS tracking unit is a device that uses the Global Positioning System to determine the precise location of a vehicle, person, or other asset to which it is attached and to record the position of the asset at regular intervals. The recorded location data can be stored within the tracking unit, or it may be transmitted to a central location data base, or internet-connected computer, using a Cellular ( GPRS), Radio, or Satellite modem embedded in the unit. This allows the asset’s location to be displayed against a map backdrop either in real-time or when analysing the Gps track later, using customized software.
