• AI and Machine Learning: Algorithms that process sensor data to predict and adapt to environmental changes in real time.
• Autonomous Decision-Making: Enabling drones to make navigation decisions without human intervention, even in complex environments.

These features collectively empower drones to operate effectively in areas where GPS signals are unavailable or unreliable.

How Drone Navigation Works in Practice

In practice, drone navigation in GPS-denied environments involves a combination of hardware and software working in tandem. Here's how it typically unfolds:

1. Data Collection: Sensors onboard the drone, such as LiDAR, cameras, and IMUs, gather real-time data about the environment.
2. Data Processing: The collected data is processed using algorithms like SLAM to create a map of the surroundings and determine the drone's position.
3. Path Planning: Based on the map, the drone calculates the optimal path to reach its destination while avoiding obstacles.
4. Real-Time Adjustments: As the drone moves, it continuously updates its map and adjusts its path to account for dynamic changes in the environment.
5. Communication: In some cases, drones may communicate with external systems or other drones to enhance navigation accuracy.

This process ensures that drones can operate autonomously and efficiently, even in challenging GPS-denied scenarios.
