Optimal Anchor Deployment and Topology Design for Large-Scale AUV Navigation
Wei Huang, Junpeng Lu, Tianhe Xu +4
Seafloor acoustic anchors are an important component of AUV navigation, providing absolute updates that correct inertial dead-reckoning. Unlike terrestrial positioning systems, the…
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…
Fast Ray-Tracing-Based Precise Underwater Acoustic Localization without Prior Acknowledgment of Target Depth
Wei Huang, Hao Zhang, Kaitao Meng +5
Underwater localization is of great importance for marine observation and building positioning, navigation, timing (PNT) systems that could be widely applied in disaster warning, u…
