PiDR: Physics-Informed Inertial Dead Reckoning for Autonomous Platforms

Researchers propose PiDR, a physics-informed neural network framework for autonomous navigation using only inertial sensors, achieving 29% positioning improvement over conventional approaches. The system addresses critical limitations of traditional deep learning by embedding physical principles directly into the model, enabling accurate dead reckoning in GPS-denied environments without requiring extensive training data.

VANGUARD: Vehicle-Anchored Ground Sample Distance Estimation for UAVs in GPS-Denied Environments

Researchers developed VANGUARD, a deterministic tool that helps autonomous drones estimate ground sample distance in GPS-denied environments by using vehicles as reference points. The system addresses critical safety issues with AI vision models that showed over 50% errors in spatial scale estimation, achieving 6.87% median error on benchmark tests.
