As far as James Bond style gadgets go GPS has got to be the best available to non 00 agents.
GPS, like most technology, has come down in price dramatically as more companies produce them.
Basically they tell you where you are and how to get to here you want to go. The system uses satellites to triangulate your position. The satellites are owned and operated by the US Department of Defence and until recently they held a few tricks up their sleeve. For them GPS is a military system, so they wanted to stop other users getting the most accurate reading. They added a code to the satellites signal and they only gave the code to their very best friends. The code is known as Selective Availability (SA) and can result in your position being as much as 250m out, and the altitude it gives is virtually useless.
GPS has taken on such a commercial importance for navigation, surveying etc. that private companies were considering sending up their own satellites. If this happened the US DOD would lose the ability to control the system. So they have decided to turn off SA, until the next war.
Good news for those that use it privately as positions will now be very accurate.
