MicronBattery Modem

Battery powered underwater acoustic modem

The Micron Battery Modem provides a reliable data link for through water communications where there are limitations on space and/or power, without the need for an external power source. Suitable for use as a stand-alone data transfer system, part of an AUV control system, or self-powered Transponder/ Responder beacon for the MicronNav USBL system.

The Micron Battery Modem is ideal for subsea data transfer applications where an external power supply may not be readily available. Utilising the internal battery power the Modem will operate in standby mode, where it’s always listening, for approximately 30 days and when transmitting with an update rate of 1 transmission every 2 seconds then the Modem will run for approximately 7 days.

When the Modem is connected to an external power source, the internal batteries act as a backup to ensure the Modem continues to operate in the event of loss of external power. The Modem provides robust spread spectrum low data-rate transmission from a compact and low cost unit with communication ranges out to 500m horizontally and 150m vertically.

The Modem can be configured for use as a data Modem, transponder or responder by using the Tritech Genesis software, while the rotary selector on the Modem allows for selection of 1 of 16 transponder IDs.

For diver tracking, the Modem is configured as a Transponder and yet allows for an external switch to be connected which can be used to send an urgent message to the surface.
