Off the shelf GPS trackers are normally accurate to within 10 metres, which for most on a regular basis use is sufficient. They are also available in codecs; the primary, information pullers give a live, real time update of the trackers place, through the use of a computer, linked to mapping software equivalent to Google Earth.

The second system requires a person to request the gadgets location, knowledge pullers. Sending it a textual content message usually does this. The GPS tracker then replies, sending back a textual content message with its present mapping co-ordinates, which in turn might be fed into a pc or traced via a mapping app on a contemporary GPRS mobile phone.
