48/78
communication and positioning devices

The 48/78 underwater acoustic modems and USBL transceivers with a horizontally omnidirectional transducer beam pattern are high-speed devices for effective transmissions in reverberant shallow waters, providing data transfer rates up to 31.2 kbit/s over a 1000 m range.

The beam pattern is optimal for horizontal transfers.

High operating frequency ensures great performance even in noisy environments.

The applications include:

  • Short-range operations in shallow waters

  • High speed communication tasks

  • Data link and positioning for AUVs and ROVs

  • Underwater acoustic sensor networks

48/78 models are available in the following product lines:

  • S2C R - highly configurable standard build, optionally as OEM without housing

  • S2C M - light and compact build for popular tasks, optionally as OEM without housing

  • S2C T - ultra-light and compact build for space-critical tasks, optionally as OEM without housing

  • S2C R USBL - highly configurable build with integrated USBL antenna for positioning, optionally as OEM without housing

  • S2C R WiSE - special edition with firmware sandbox for developers
