What is GPS? - Location Tracking

The video explains how GPS works using satellites to determine your location through triangulation. It describes how SAT NAV devices receive signals from satellites to calculate distances and pinpoint locations. The video also covers how digital maps are used for navigation and how SAT NAV continuously updates your position during a journey.
