Real Time Tracking means that a GPS Tracking device sends its location to the end user at a consistently high frequency.
GPS Tracking devices communicate their positions by taking the signals received from Satellites and transmitting them to a server, which then sends this information to the program being used to see the tracking device.
Many GPS tracking devices rely on the user sending a request to the server which activates the tracking device and gets it to transmit its location back to the program being used. If your tracking device is on the move, this means that the location your receive is not the real location of your device, as there is an extended delay between the positional update and the tracker location.
Trax devices update their location in the Trax app up to every 10 seconds. This means that you can see your Trax device moving on the map as it receives new positions, in real - real time!
