Long Range Underwater Acoustic Communication

 

Discover how Sercel and Naval Group achieved reliable underwater acoustic communication over distances up to 40 km.

This case study demonstrates proven solutions for Very Low Frequency (VLF) communication challenges in undersea operations:

• Advanced MATS modulations adapted for narrow-bandwidth VLF transducers
• Compact Digital Acoustic Vector Sensor technology for directivity gain
• Validated performance in real-world sea trials across varied seabed conditions
