GPS stands for Global Positioning System and it is a navigational tool, which uses satellites to show you where you are on earth. If you have a GPS-enabled mobile phone, you will get turn-by-turn and traffic information on your smartphone screen. The system has become a blessing for all the travelers who always want to reach their destinations on time due to bad weather, traffic jam, or if they get lost. In fact, with a GPS, you can even plan your route on a map and can determine the right lane to take.
Global Positioning System (GPS), works on the premise of the global positioning system, a navigation tool that utilizes the satellite signals to show you your present location. This is done by a constellation of satellites that circle the earth twice a day. GPS is able to function 24 hours a day, in any weather and climatic conditions on any portion of the earth’s surface. It transmits data about your location and the direction you are heading towards. The main components of GPS include the unit with the built-in GPS receiver, satellites, cables, and software which allow the data to be received and interpreted by the computer.
The GPS receivers come in two types, ones that receive their signals through the air and ones which are connected to the user’s GPS device. With the help of these two devices, a person can use a global positioning system to measure distance, time, and altitude. The other feature of a GPS device is the ability to store the location of the last three GPS locations. This data is then sent back to the central control station of the GPS. GPS has made driving and navigation easier not only for the drivers but also for the emergency personnel and other people on the road.
