Gavia AUV Gets a Sonar Upgrade
Teledyne Gavia has continued the enhancement of its modular, versatile, low-logistics subsea survey solution, the Gavia autonomous underwater vehicle (AUV), this time with the addition of a new Side Scan/Bathymetry module.
Incorporating Klein Marine Systems’ new UUV-3500 high-resolution side scan sonar with optional bathymetry sonar, the system is another high quality option for customers interested in utilizing the Gavia AUV for geophysical survey, cable and pipeline survey, environmental survey and under ice survey, as well as Mine Countermeasures (MCM), Rapid Environmental Assessment (REA) and Intelligence, Surveillance and Reconnaissance (ISR) surveys.
The modular Gavia AUV can carry an array of sensors and custom payload modules to a survey site in up to 1,000m water depth for research, monitoring, survey or surveillance tasks.
Equipping the Gavia AUV with the survey-grade long range side scan from Klein Marine Systems creates a highly mobile survey platform with high quality side scan range and resolution. The swath bathymetry option allows for wide swath performance which is typically ten to twelve times the overall altitude of the AUV. The new module allows customers to have both side scan and swath bathymetry from a single module. The first delivery of the Klein UUV 3500 Module will occur in Q1 of 2017 and is integrated with the SeeByte Autotracker software for autonomous pipeline tracking. The Gavia AUV can also be equipped with a camera and strobe system for close inspection of any targets identified by the sonar system.
“The Gavia AUV’s accurate navigation capability combined with the long range, wide swath data provided by the Klein UUV-3500, make this a highly efficient solution for a variety of commercial, military and scientific applications. Geophysical surveys can also be conducted by adding the swath bathymetry option, Teledyne Benthos sub-bottom profiler module and environmental sensors” commented Arnar Steingrimsson, Global Head of Sales – AUVs at Teledyne Marine.
In addition to the release of the Klein sonar module, Teledyne Gavia has recently released two other upgrades to its vehicle.
- The upgraded Gavia battery module has more than a 20 percent increase in capacity thanks to a partnership with Teledyne Energy Systems, Inc. In addition, a high efficiency power management system was developed by Teledyne Gavia to optimize the performance of the batteries.
- A new and improved nozzle actuator has also been released. The new nozzle increases the volume of compensation to better deal with deep water operations and temperature variations.
