Can you build a drone that flies autonomously from point A to point B without using GPS? It might seem like a challenge at first, but I believe it's entirely possible. Drones typically rely on GPS for navigation. However, in some environments, such as indoors or areas with weak satellite signals, GPS may not be reliable. This raises the question: how can we enable autonomous navigation without GPS? One solution lies in the use of cameras and advanced image recognition. Imagine equipping a drone with a downward-facing camera, continuously capturing images of the ground below. Here's how it would work: First, we load satellite images or high-resolution maps into the drone's onboard memory. These maps serve as a reference for the drone. As the drone flies, it constantly compares the live images from the camera with the preloaded satellite map. By using software that matches the drone’s current view with the map, the drone can identify its location and adjust its course in rea
