Navstar GPS

Navstar GPS, commonly called GPS, is a satellite-based navigation system that provides accurate location and time information anywhere on Earth. It works by using a network of at least 24 satellites orbiting the planet, which send signals to devices like smartphones or GPS units. These devices interpret the signals to determine their exact position, speed, and direction. GPS is widely used for navigation, mapping, logistics, and many other applications, offering reliable and real-time geographic information globally without the need for internet connectivity.
