The Global Positioning System (GPS) is a combination of satellites which is able to accurately identify the location, direction, speed and time of a person anywhere on Earth. The US military developed GPS over twenty years ago and US President Ronald Regan allowed the public access to the system during his time in the oval office. This means that today anyone can use the system provided they have a working GPS device.

In recent times there have been some tremendous advances in the technology behind GPS or Global Positioning Satellites, and now this exciting technology is available to the general public. There are many uses for GPS, but the particular use we will be looking is the benefit relevant to the motorist. Car GPS units enable you to navigate your car anywhere in the world. Tracked by GPS satellites, they are able accurately tell where you currently are, how to get to your chosen location and the best route to get there.

The in-car system comprises of an easily mounted small unit which you attach to your windscreen or place on your dashboard. The great benefit is that once you have the unit installed in your car, you just key in your required destination, it will then give you turn by turn directions by voice and in real time. This is extremely useful for any travelers who are in an unfamiliar area, which of course applies to most of us at one time or another. A lot of car rental firms are installing GPS systems in their entire fleet of vehicles as an aid to their customers, and of course this also has advantages for them.
