The Global Positioning System or the GPS is a tracking system that was developed by the U.S. Department of Defense made into the reach of the civilians during the 1980s. The technological advancements in the field have resulted in the employment of 24 to 32 medium Earth orbit satellites to map the real-time location. The receiver embedded in the GPS locks up the signals from three or more satellites to plot the location using a technique called trilateration. The time at which the signal was sent from the satellite is compared to the time at which it is acknowledged to identify the position. GPS can be made to provide data about the distance to the destination, hiking and water maps, sunrise and sunset timings and much more on a real-time basis.
Today GPS has changed the way of communication largely. One can find a number of GPS products that suit for the people on the road, water, air, hiking, and even those in active sports. Original Equipment Manufacturers has also understood the role played by it and has included them in many of the products from transportation to recreational applications.
