S2C M Mini Modems

The S2C M series of "mini-modems", a product line designed for size- and weight-sensitive applications, is ideal for integration with modern UUVs.

S2C M modems are fully compatible with S2C R Modem, USBL and LBL ranges. They can extend existing infrastructure and seamlessly integrate into EvoLogics navigation and positioning systems.

Any S2C M "mini" 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.

For easier system integration, all S2C M "mini" Modems are available in OEM versions without housing.

Applications

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