global positioning systems

Global Positioning Systems (GPS) are satellite-based navigation tools that determine your exact location on Earth. They work by using a network of at least 24 satellites orbiting the planet. When you use a GPS device or smartphone, it receives signals from nearby satellites, which include precise time and position data. The device calculates its distance from multiple satellites and uses this information to pinpoint your position via triangulation. GPS is widely used for navigation, mapping, and location-based services, providing accurate location information anywhere with a clear view of the satellites.
