This is where the high-tech GPS units come in today's life. There are more than 24 GPS satelites that orbit around Earth that put out timing signals by radio. This allows any GPS unit to accuratly determine its Longitude, Latitude, Altitude, time and speed anywhere on Earth.

The GPS wasn't available to civilians until recently. It was originally named NAVSTAR GPS and was developed by the United States Department of Defense which launched the first experimental satalite in 1978.

Today the GPS is accurate to as close as a 1ft. making navigating to an exact point easy. With todays GPS units available for Vehicles, Boats, Planes, Helicoptors, Bicycles and portable Handhelds you can go anywhere in the world with one.

There are many different uses for GPS systems. I mainly use one for boat navigation. Traveling 50-100 miles offshore with just a compass can get downright scary once you look back and land is nowhere to be seen. A friend of mine is a hunter and he likes to walk upto 5 miles into the forest. Without a GPS he'd never get back to his truck. My wife has one in her car, she puts in an address and it will give you the best directions to that address. It even tells her when she's passed her turn and recalculates a new direction to get her where she needs to go. It is truely a wonderful thing to have and can help the direction illiterate's get anywhere they need to go like the inlaw
