UAP.Com

Underwater Acoustic Modem

A versatile HF/VHF underwater acoustic modem providing reliable long‑range communication, ranging, and data logging, low‑power standby, and housings for shallow‑water or 6,000 metre deep sea deployments

The Develogic UAP.COM is a flexible HF/VHF underwater acoustic modem designed for reliable subsea communication, ranging, and device control. NATO-standards compliant, it supports forward‑error correction, transparent data compression, and bi-directional handshaking to maintain stable links in both simple and complex acoustic environments.

Offering data rates up to 4.1 kbit/s (VHF) or 2.1 kbit/s (HF), it enables long‑range communication between seafloor landers, underwater vehicles, and surface vessels. With RS‑232/422/485, Ethernet, and OEM interfaces, plus optional data logging up to 512 GB, it integrates easily into diverse systems.

Available in POM‑C (100 metre depth rated) or Titanium (6,000 metre depth rated) housings, it is engineered for dependable performance in demanding marine operations in defence, offshore energy and ocean science.
