Fetch Ambient-Zero-Ambient (AZA) is a long-life subsea sensor logging node that enables data to be wirelessly extracted via its integrated high speed acoustic modem.

The high quality pressure sensor is automatically recalibrated in situ allowing consistently accurate readings over a deployment period of up to 10 years.

Sensors are powered only when required and data is logged and time stamped an internal SD memory card.

Other supported sensors include high precision temperature and sound velocity as well as inclination.

The 9000 bits per second modem transfer rate enables logged data to be extracted in minimal vessel time, reducing operational costs.

The ultra-low power platform powers up sensors only when required and logs and timestamps the data to an internal SD memory card.

Fetch is compatible with Sonardyne’s Ultra-Short BaseLine (USBL) positioning systems for positioning during deployment/recovery.
