How a GPS works step by step?
Here’s how GPS works in six steps:
- GPS works by using a method called “triangulation” or “trilateration”.
- It needs to get a message from at least three, preferably four satellites.
- To “triangulate”, a GPS receiver measures the distance between itself and each satellite.
What is a GPS and how does it work?
The Global Positioning System (GPS) is a network of about 30 satellites orbiting the Earth at an altitude of 20,000 km. These signals, travelling at the speed of light, are intercepted by your GPS receiver, which calculates how far away each satellite is based on how long it took for the messages to arrive.

GPS stands for Global Positioning System. A special radio receiver measures the distance from your location to satellites that orbit the earth broadcasting radio signals. GPS can pinpoint your position anywhere in the world.
How does GPS work without Internet?
GPS does not need any kind of internet or wireless connection, but there are technologies like A-GPS that use the mobile network to shorten the time to first fix, or the initial positioning or increase the precision in situations when there is a low satellite visibility.
