Drone navigation systems utilize a combination of GPS (Global Positioning System), computer vision, and inertial measurement units (IMUs). These technologies work together to provide accurate positioning and stability in flight. GPS offers real-time location data, while computer vision enables drones to identify and avoid obstacles. IMUs track the drone's orientation and movement, allowing for precise control. Additionally, machine learning algorithms may be employed to enhance navigation capabilities by analyzing flight patterns and environmental data, ultimately improving the drone's autonomy and efficiency in various applications, from delivery services to aerial photography.
