The S2CM HS Modem can be supplied with a cable mounted transducer (up to 1.5 m cable length) to simplify system integration for UUVs or diver tracking systems.


  • Communication and positioning for AUVs and ROVs
  • Diver tracking and communication systems
  • Size- and weight-sensitive applications
  • High-speed communication in adverse conditions
