Space-based positioning system
A space-based positioning system, like GPS, uses a network of satellites orbiting Earth to determine your precise location. These satellites constantly send signals to receivers on the ground, which measure the time it takes for the signals to arrive. By calculating how long the signals take from multiple satellites, the system can pinpoint your position with high accuracy. It’s like having a universal, satellite-powered map that works anywhere on Earth, regardless of weather or obstacles, providing vital navigation information for driving, flying, maritime, and many other applications.
