How GPS Calculates Your Position | Trilateration Explained

Unlock the real science behind GPS! In this video, we explain the biggest misconception in navigation: GPS does NOT use triangulation — it uses trilateration. Learn how GPS receivers calculate your exact location using distance measurements, satellite timestamps, and the power of the speed of light. We break down the difference between trilateration and triangulation using clear animations and examples that every GIS and geospatial student can understand. 🌍 In This Video You Will Learn: ✔️ How GPS receivers measure distance using timing ✔️ Why GPS requires at least 4 satellites ✔️ How trilateration works step-by-step ✔️ Why triangulation is NOT used in GPS ✔️ Real examples of distance-based vs angle-based location methods ✔️ How satellites broadcast their positions #gps #gnss #Trilateration #triangulation #geospatial #surveying #navigation #SatelliteTechnology #Geoinformatics #GIS #earthobservation Whether you're into GIS, surveying, geodesy, GNSS, or remote sensing, this tutorial will help you finally understand how GPS actually works.
