Eyetek sell two types of car tracking devices The first and by far most popular type is the live car tracker  this type of tracker reports back in real time showing the trackers position on a  moving map display as often as every 5 seconds.
The tracker obtains its position by using the GPS  system (Global Positioning System)  The GPS system uses 24 satellites travelling in 6 orbital paths around the Earth at a distance of 12,600 miles. These satellites transmit a low power signal The pattern of their orbit is calculated so that a GPS receiver on the earth’s surface is always ‘visible  to at least 4 of these satellites. From these 4 satellite transmissions your GPS Tracker can work out its location to within a few metres. This is the same system used by car sat nav systems and is extremely accurate.
The tracker then sends its position data back to our web server via  GPRS on the mobile phone network to report its position this can be as often as every 5 seconds or if regular updates are not required much longer time spans can be selected.

Data loggers which records the historic data every few seconds and stores this in its onboard memory for download to your PC at a later date, with this type of device the logger needs to be removed from the target and plugged into your PC via the USB port to download the data and view via the mapping software.
