An Overview Of GPS SystemsBy Chris Simons GPS stands for global positioning system, a system that has been established and is managed by the Department of Defense. The GPS system utilizes satellites that have been put into orbit that help people determine their exact location whether it be for the purposes of personal navigation, military activities, or any type of enterprise that requires an exact global positioning by latitude, longitude and altitude. GPS systems are installed in automobiles, motorcycles, some PDAs, Airplanes, dog collars, fishing boats, and so many other products. GPS systems all started out in the army in the year 1970. In the army, many soldiers needed navigation systems to know their directions around other countries. Without this device it would be really hard for them to find their way around. This device has saved soldier's time in war and has also saved many lives. GPS systems are very powerful devices and are a great navigation system to use to get around. GPS systems have gone for beyond just serving the army. They now serve just about everyone. These navigation systems help drivers find there way through city streets and help hikers find their way through the rough terrains of the mountains. They also help pilots find their way around the skies as well as helping mariners find their way around the great sea. The GPS systems technology can help serve anyone in need of it. GPS systems can also be purchased for motorcycles, and hikers sometimes use such systems to determine where they are while walking. Cyclists should not be left out of the mix, and runners, joggers, and skiers use navigation systems to prevent themselves from becoming lost in an unfamiliar area. Some PDAs - personal digital assistants - are equipped with built in navigation devices, while some Palm devices also include such systems. Navigation systems are sold with a variety of features and what kind of features you should look for is solely dependent on two factors - price and need. The most basic of navigation systems will provide you with a route from one point to another point or to multiple points, depending on your destination and trip plan. A benefit of such navigation systems is that they not only serve as a guide to your preplanned destination, they also serve as guide back to where you started. Any route you plan in a navigation system is completely reversible thanks to the innovative design of such systems. Alternatively, you may pay more money for a navigation system that has voice capabilities. You can purchase a navigation system that will guide you to your destination vocally and while speaking to you it will offer up a turn-by-turn dictation of your journey. Conversely, those individuals that spend the majority of their time traveling - like a delivery man may find that they prefer a navigation system that they can preplan many destinations at one time and then move from one set of directions to another. Thus, such individuals require a uniquely designed navigation system -one that possesses multi destination capabilities. Finally, there are different navigation systems for boats, motorcycles, cars, and joggers so you will need to be sure to purchase the product you require for your intended use. The most popular GPS Systems are made by: Navstar, Magellan, Garmin, Slim Trak, Cobra, Holux, Suunto USA, and Timex. Chris Simons is a prolific freelance writer.
