An Attention-Assisted AI Model for Real-Time Underwater Sound Speed Estimation Leveraging Remote Sensing Sea Surface Temperature Data
Pengfei Wu, Wei Huang, Yujie Shi +2
The estimation of underwater sound velocity distribution serves as a critical basis for facilitating effective underwater communication and precise positioning, given that variatio…
Optimal Reference Nodes Deployment for Positioning Seafloor Anchor Nodes
Wei Huang, Pengfei Wu, Tianhe Xu +2
Seafloor anchor nodes, which form a geodetic network, are designed to provide surface and underwater users with positioning, navigation and timing (PNT) services. Due to the non-un…
Future Full-Ocean Deep SSPs Prediction based on Hierarchical Long Short-Term Memory Neural Networks
Jiajun Lu, Hao Zhang, Pengfei Wu +2
The spatial-temporal distribution of underwater sound velocity affects the propagation mode of underwater acoustic signals. Therefore, rapid estimation and prediction of underwater…
Underwater Sound Speed Profile Construction: A Review
Wei Huang, Jixuan Zhou, Fan Gao +6
Real--time and accurate construction of regional sound speed profiles (SSP) is important for building underwater positioning, navigation, and timing (PNT) systems as it greatly aff…
