 The Gavia, Autonomous Underwater Vehicle (AUV), is a fully modular, man portable vehicle available in depth ratings in excess of 1000 meters and custom vehicles with depth ratings of 2000 meters.
It has been in development from 1997 when the Gavia program was started as a joint development with the University of Iceland.
The Base Unit
The Gavia AUV system developed by Hafmynd LTD, is a commercially available fully modular compact AUV capable of both very shallow water and deep water operations. The Gavia base vehicle is a mobile sensor platform that can be configured on deck for a particular task or operating condition by the addition of one or more Gavia sensor, navigation, or battery modules, which are inserted into the vehicle and locked in place by means of a unique twist lock system.
Specifications:
