Researchers have developed DVL-DeepONet, a novel physics-guided deep neural operator framework designed to improve the resilience of underwater navigation systems. This framework addresses challenges faced by Autonomous Underwater Vehicles (AUVs) when DVL sensors provide noisy or incomplete data, or when inertial sensors are absent. DVL-DeepONet learns to map temporal sensor observations directly to vehicle velocity, enforcing physical constraints to ensure robust estimation even under degraded sensing conditions. Experimental results from real-world AUV missions covering approximately 10,000 meters show that DVL-DeepONet outperforms existing model-based and learning-based approaches by up to 40%. AI
