Long before Global Positioning System (GPS) arrived, researchers worked hard to arrive at a feasible solution to aid travellers from getting lost. Earlier, travellers used to rely on elaborate maps to track and monitor the route to their destination. But today, GPS technology has ensured hassle – free trips and increased safety for vehicle owners.GPS works all across the world and in all weather conditions, thus helping users track locations, objects, and even individuals! GPS technology can be used by any person if they have a GPS receiver. The GPS satellites rotate twice a day around the earth in a specific orbit. These satellites transmit signal information to earth.
