Today GPS (Global Positioning System) has become very popular. The system consists of 24 satellites that can be used for tracking and navigation. Personally I have been thinking about getting some kind of GPS for my boat so I can mark on a map where I got caught big amounts of fish. This would make it very easy to find the same fishing spot again as you are able to mark with an accuracy of a few meters.

Another use of GPS is vehicle tracking where you can track every movement that a vehicle is doing.
A company that sells a tracking system like this is Vehicle-Tracking.com. With their small tracking key you can track every movement of a vehicle. The device sends out a signal every second and is able to record the position within 2.5 meters, making the system very accurate.
Another great feature with this system is that you can upload the recorded data to Google Earth and since the tracking key got USB you can connect it directly to any computer making it easy to use. By using Google Earth you get to see in great detail every movement that the vehicle has been doing.
The tracking key has a magnet mount and is water resistant so you can even put the small and easily concealable device on the underside of a vehicle.

Vehicle-Tracking.com ships their vehicle tracking system to all states in the US.
