Charting the Course: Understanding How Drones Navigate

How drones navigate is a result of a harmonious blend of advanced technology and complex algorithms. From GPS systems to onboard sensors, let’s delve into the fascinating mechanisms that enable drones to traverse the skies.

GPS: The Guiding Star

Global Positioning System (GPS) plays a pivotal role in drone navigation. Drones use GPS signals to determine their position relative to specific waypoints, enabling them to follow pre-defined flight paths or return to a home location.
