R-Series Underwater Acoustic Modems

 

S2C R series of underwater acoustic modems provide full-duplex digital communication using the EvoLogics patented S2C (Sweep-Spread Carrier) Technology, delivering an excellent performance, resistant to the challenges of a dynamic subsea environment. Self-adaptive algorithms adjust the S2C parameters to maintain the highest bit rate possible in current conditions.

 

The S2C R series offers a selection of short- mid- and long-range devices for shallow or deep water applications. Each product is available in a variety of configurations to offer the best-fit solution for a particular scenario.

 

Every S2C R Underwater Acoustic Modem was designed as a reliable tool to solve multiple communication tasks. It implements advanced data delivery algorithms, supports addressing and networking and is easy to control with a comprehensive set of commands and software-configurable settings.

 

M-Series Underwater Acoustic Mini-Modems

 

The S2C M-series offers the full benefits of the company's patented S2C (Sweep-Spread Carrier) communication technology in a light and compact design.

 

The S2C M-series is fully compatible with EvoLogics standard S2C R and S2C R USBL series and includes a selection of directional and non-directional short- and mid-range devices that fit various application scenarios, especially those where size and weight are critical. The M-series relies on EvoLogics S2C broadband communication technology to overcome the challenges of dynamic underwater environment and deliver a great performance in various subsea conditions. S2C M-series modems are smaller and lighter than the standard EvoLogics R-series devices, but deliver the uncompromising performance of the full-sized product line.

HS Series Underwater Acoustic Modems

 

The new high-speed mini-modem offers incredible 62.5 kbps for short-range transmissions.

 

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.

 

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.

 

Applications

  • Communication and positioning for AUVs and ROVs

  • Diver tracking and communication systems

  • Size- and weight-sensitive applications

  • High-speed communication in adverse cond
