Tritech Micron Data Modem – Acoustic Modem

Underwater Acoustic Modem

The Micron Modem is an exciting development in the field of through-water communications; providing a robust spread spectrum data transmission from an extremely compact unit.


The Micron Modem has been designed to provide a reliable data link for through water communications where there are limitations on space and/or power. Suitable for use as a standalone system or part of an AUV control system.


  • Through water communications
  • AUV control and data collection


  • Low error rate
  • Low power consumption
  • 500m horizontal range
  • 150m vertical range


  • Multipath noise rejection
  • Compact size
  • Easy to install

The Micron Modem provides robust spread spectrum data transmission from an extremely compact and low cost unit. Due to its miniature size and low weight, the Micron Modem is suitable for a host of potential sub-sea data transfer applications that were previously impractical or uneconomic with larger, more expensive systems.

The system is able to transmit a maximum data rate of 40 bits per second, making it suitable for a range of through-water, low data rate transfer requirements.

The Micron Modem can also be configured as a transponder or responder, to operate with a Tritech USBL transducer as part of a MicronNav 200 positioning system.

The Micron Modem is also available as a battery powered option in the Tritech Micron Battery Modem about which more information can be found on the Tritech website.
