Overview
Lighthouse's Teledyne Gavia Offshore Surveyor AUV is a self contained, low logistics, modular survey platform, capable of delivering high quality data while operating from vessels of opportunity or from shore.

The Gavia AUV comprises multibeam echosounder (MBES), side scan sonar (SSS) and sub-bottom profiler (SBP) payload and allows Lighthouse to perform detailed surveys down to 1,000m water depth and to work very close to platforms and targets. Very easy deployment, great data quality, and fast survey execution are the main benefits of the Gavia AUV.
