An Asynchronous Two-Speed Kalman Filter for Real-Time UUV Cooperative Navigation Under Acoustic Delays
arXiv:2604.02878v2 Announce Type: replace Abstract: In Global Navigation Satellite System (GNSS)-denied underwater environments, individual unmanned underwater vehicles (UUVs) suffer from unbounded dead-reckoning drift, making collaborative navigation (CN) crucial for accurate state estimation. However, the severe communication delay inherent in underwater acoustic channels poses serious challenges to real-time state estimation. Traditional filters, such as Extended Kalman Filters (EKFs) or...
Neural Radiated-Noise Fields for Unmanned Underwater Vehicle Noise Spectrum Prediction in Three-Dimensional Scenes
Announce Type: cross Abstract: Radiated noise in unmanned underwater vehicles (UUVs) is an important indicator for characterizing acoustic signatures and evaluating platform performance. To address the strong dependence of traditional physics-based modeling and numerical simulation methods on target structural information and environmental boundary conditions, and their inability to achieve continuous spatial spectrum-response modeling in three-dimensional scenes, this paper proposes a...
AUKUS unveils undersea drone project to deepen defense partnership
The military alliance of Australia, the United Kingdom and the United States will jointly develop new undersea drones, U.S. Defense Secretary Pete Hegseth announced on Saturday. “We are accelerating delivery of advanced capabilities to our war fighters, and together today we are pleased to announce the first AUKUS ‘Pillar Two’ signature project focused on fielding advanced uncrewed undersea vehicles, or UUVs,” Hegseth told a press conference in Singapore. “The signature...
From Agni 5 to Akash & hypersonics: Decoding India's homegrown arsenal & defence shield
The ongoing conflicts in Ukraine, on the borders of Israel and in the Persian Gulf have underscored the importance of indigenous defence technologies and a domestic industry to back innovation. India has been steadily working to become self-reliant in defence manufacturing. The country is now on a razor’s edge—designing, developing, and deploying homegrown defence technologies.
