GPS: The Global Positioning System Revolution

What is GPS?
The Global Positioning System (GPS) is a satellite-based navigation system that provides location and time information anywhere on Earth. Developed by the U.S. Department of Defense and made fully operational in 1995, GPS has since become essential for civilian and military use.

How Does GPS Work?
A network of 24+ satellites orbits Earth, transmitting signals to GPS receivers (like smartphones or car navigation systems). By calculating the time it takes for signals to arrive from multiple satellites, the receiver determines its precise location (latitude, longitude, and altitude).

Key Applications of GPS
Navigation – GPS powers apps like Google Maps, Waze, and car navigation systems, helping users find routes in real time.

Emergency Services – Rescue teams use GPS to locate accident victims or disaster zones quickly.

Fitness & Sports – Runners and cyclists track their routes using GPS-enabled smartwatches.

Logistics & Delivery – Companies optimize delivery routes, saving time and fuel.

Agriculture & Surveying – Farmers use GPS for precision farming, while surveyors map land accurately.

Future of GPS
With advancements like GPS III satellites (more accurate and secure signals) and integration with 5G and AI, GPS technology continues to evolve, enabling smarter cities and autonomous vehicles.
