tracker A tracker is a device capable of determining its position using GPS satellites.

Trackers determine and record their position at a predetermined interval and send this information to the IneTrack servers through the very same GSM network that is used by mobile phones. For this communication, a SIM card is needed, just like in the case of regular mobile phones. Tracking devices also have built-in memory, where they can store the recorded data, so there is no data loss even if the tracker cannot establish a connection with the servers for some reason.

To interpret GPS signals, trackers contain a GPS receiver unit, which is responsible for calculating the position of the device.

Besides recording position data, some trackers can also react to certain events, such as the turning of the ignition switch, opening of a door, SOS signal, and so on.
