GPS navigation system is a mainstay of transportation systems worldwide, offering navigation for aviation, ground, and maritime operations. Disaster help and emergency units, news agencies utilize GPS systems for locating & timing their life-saving missions. Everyday people activities such as driving, cell phone operations, atomic watches, computers are facilitated by the precise timing provided by Global Positioning Systems. Geologists, drivers, pilots, bikers and others perform their duty more efficiently, conveniently, economically, and precisely using the free and open Global Positioning System signals.
