In simple terms, the GlobalTrack onboard system reads the GPS position data and then transmits the data to a tracking server and then on to the user’s monitoring computer. The data from the vehicle to the tracking server can be transmitted over the mobile telephone network (GSM/3G/4G), WiFi network, or Satellite connection. From there the connection to the user’s computer is either sent over the user’s local network (LAN), or via the internet.
At a minimum, the onboard equipment consists of a computer (tracking device), GPS antenna, and GSM, 3G, 4G, WiFi or satellite antenna. In addition, many types of optional sensors can be added to give additional information.
