Differentiating Between GPS and Sat Nav

GPS or Global Positioning System is the name of a satellite group which is orbiting around the planet. Decades ago, the United States Government placed them there. But it was only during the Reagan administration that they were made available for public use. A person can get his precise location on the planet, provided as a set of coordinates by utilising a GPS receiver. This is a tiny device that can receive and send signals from any of these satellites within range. When you know the coordinates for your own location, you can use a GPS receiver to guide you to any place utilising an arrow icon on your device. Theoretically, if you know the GPS coordinates of your office, you can find your way using a receiver even if you are in the middle of the Sahara desert. There are now many gadgets that come with a built-in GPS receiver such as mobile phones, motorbikes, cars, sea vessels, and many more. A lot of PDAs and smart phones often have a built-in GPS feature. It is possible to use he GPS applications to direct you to any destination such as a restaurant, cinema, tourist spot, and more. There are even a few digital cameras fitted with a GPS which record exactly where the person took a particular photograph. Meanwhile, Sat Nav or Satellite Navigation is a very intelligent software that utilises GPS signals. It combines the coordinates coming from the GPS signals with a comprehensive map. When you use the software and input your destination, it will calculate a route for you which will lead to where you wish to go. Since the GPS signal is regularly updated, the Sat Nav can provide you with step-by-step instructions on your current location and in what direction you should drive, which road to follow, and when to make a turn.
