GPS is now widely used in vehicles. More and more drivers use the Vehicle GPS to find their ways. GPS systems allow a driver to keep track of where he or she is and suggest the best route to follow to reach a designated location. With a touch-sensitive screen, a GPS unit puts programming and operation literally at your fingertips to make sophisticated technology simple. The built-in database offers millions of points of interest for you to use as destinations or reference points as you plan your trip. Today, a Car GPS also provides a selection of available routes, giving you the option of avoiding toll roads or choosing between the quickest or the most scenic routes. The database includes zip codes to simplify your route selection, and for extra convenience, it lets you save the addresses of frequent destinations, making route planning easier and faster than ever. Other display features include a compass mode to assist you with directional orientation, and an anti-glare screen for optimal viewing even in direct sunlight.

GPS is popular among hunters, hikers, runners, bikers, golfers and travellers. It is a useful tool for sports and outdoor activities. Actually, anyone who needs to keep track of where he/she is, to find his/her way to a specified location, can be benefit from using GPS. For example, a GPS can be very useful when hunting unfamiliar territory. In an unfamiliar area, you may find that it is easily to get lost: The woods around you are varied, but a few miles down the road there are acres and acres of continuous woods, which looks the same. In a case like this, it's just good insurance to have a GPS to avoid one from losing his way.

GPS was original designed for military use. A GPS unit can help geo-locate and destroy an enemy's stronghold, and save soldiers? life. Today, weapon systems are designed to use GPS data as input for targeting and guidance. Cruise missiles commonly used by US to accurately hit targets from large standoff distances use multichannel GPS receivers to accurately determine their location constantly while in flight.

The use of GPS technology in science field work is increasing rapidly. GPS is being used in aviation, nautical navigation and for the orientation ashore. It is also used in land surveying and other applications where the determination of the exact position is required. The scientists use GPS for its precision timing capability and position information. For example, surveyors use GPS for an increasing portion of their work. Recording locations for water samples, mineral specimens, animal sitings and more. These can be quickly marked in the field and then archived in the office or plotted on maps. GPS is faster and more accurage than using a paper map. GPS offers cost savings by drastically reducing setup time at the survey site and providing incredible accuracy.

Rescue and emergency response is another area where GPS can prove invaluable to the rescue team. Determining the location of a casualty during operations, emergency response teams can use the GPS to reduce response time. With a GPS receiver and a communications radio, a search and rescue team can locate a target faster and more accurately than before.

Using GPS to track a pet is relatively new. The movements of a pet can easily be monitored with a transmitting GPS unit. With the growing popularity of GPS, there are many companies offering GPS for pet tracking. For example, the GPS-based dog location system enables you to quickly find where your dog is. It pinpoints your dog's position and shows you exactly where to find the dog, and the distance between you and your dog. A GPS Dog Tracking System has two components: a handheld receiver and a dog collar transmitter. For example, Garmin Astro GPS Dog Tracking System includes a bright, color-screen handheld Astro 220 GPS device and a wireless transmitter, called the DC 20. The DC 20 transmits your dog's position to your handheld every five seconds, showing current location as well as where he's been on the Map page. The Dog Tracker page shows you a compass that points to your dog's location.
