Teledyne Gavia is a leading manufacturer of modular, low logistics autonomous underwater vehicles for commercial, scientific and defence sectors. Typical applications include bathymetric / sub-bottom / side scan surveys, pipeline and platform inspections, post-hurricane inspection, pre / post lay, build and sub-bottom surveys, exploration and construction support, and UXO / MCM surveys.

Teledyne Gavia is a division of Teledyne Technologies. This affiliation gives Gavia the support of a large diverse organisation whose companies design and manufacture leading underwater sensors, connectors, communications and positioning systems.

Low logistics autonomous underwater vehicles

The Gavia AUVs are man-portable, low logistics AUVs capable of performing complete commercial surveys (side scan, bathymetry, and sub-bottom). They can be deployed from the shore, small craft, or vessel of opportunity. Their relative small footprint and broad capabilities make them an asset to any operation.

Gavia AUVs are fully modular, with field-swappable components that give operators great flexibility. Modules can be swapped in-situ to change batteries or sensors as mission criteria changes. Both standard and custom modules are available.

Navigation and communication options

The Gavia AUV offers a variety of solutions for navigation and positioning. Available equipment includes a high-accuracy DGPS-ready receiver for surface navigation, high-precision DVL-aided INS and direct-sound velocity meter for in-water navigation. Ultra-short baseline (USBL) and long baseline (LBL) positioning solutions can also be added to improve positioning and accuracy on survey routes and for other deep water applications.

Communication options include wireless LAN, Iridium and acoustic modem.

Diverse payloads

Gavia AUVs can carry a variety of payloads and sensors including side scan, swath bathymetry, sub bottom profiler, cameras, and an array of environmental sensors. Custom payload modules for user-defined sensors are also available.

AUVs for research, monitoring and surveillance

The Gavia AUV can carry an array of sensors and custom payload modules that make it perfect for any research, monitoring or surveillance task. The key features of the Gavia AUV are its relatively small size (man portable), and its modular design, which allows users to change sensors and batteries as needed. The system has the greatest depth rating in its class (500m and 1,000m) and is used for a variety of tasks for military, commercial and scientific applications.

About the Gavia autonomous underwater vehicle programme

The Gavia autonomous underwater vehicle programme began in 1997 as a joint project between Hafmynd ehf of Reykjavik, Iceland, and the University of Iceland to develop improved capability remote sensing solutions with unmanned vehicles. Initial Gavia vehicles were sold to domestic customers in Iceland starting in 2000. Shortly thereafter, they gained international appeal with scientific users who understood the benefits of the modular construction and custom payload design.

Since 2008 the Gavia AUV has increasingly been used by commercial survey companies. Hafmynd ehf was acquired by Teledyne Benthos, a subsidiary of Teledyne Technologies, in 2010.
