What is GPS and how does it work on my phone?
GPS, or Global Positioning System, is a network of satellites orbiting the Earth that provide location information to GPS receivers on the ground. On your phone, GPS works by communicating with these satellites to determine your exact location, speed, and direction of travel. This information is then used by various apps, such as maps and navigation, to provide you with turn-by-turn directions, estimated arrival times, and other location-based services.
When you use GPS on your phone, it sends a signal to the nearest cell tower, which then communicates with the GPS satellites to determine your location. This process is called trilateration, and it involves measuring the time delay between when a signal is sent and when it is received. By combining the data from multiple satellites, your phone can calculate its exact location and provide you with accurate navigation information.
