VLIZ Takes Delivery of a Gavia AUV

Teledyne Gavia announced that after an international tender it has completed the sale and recent sea acceptance testing of an autonomous underwater vehicle (AUV) to the Flanders Marine Institute (VLIZ) in Oostende, Belgium.The VLIZ Gavia is rated to 1,000m depth in a low logistics form factor and includes an array of scientific instruments to meet current and future VLIZ research requirements. The modular nature of the GAVIA AUV allows sensors to be added as mission requirements dictate. The VLIZ Gavia is configured for diverse research applications and includes an iXblue INS coupled with a Teledyne

Teledyne Gavia will formally introduce its new 6000 meter rated AUV --  SeaRaptor --  at Ocean Business 2019 in Southampton in April.

Teledyne Gavia: New SeaRaptor 6000m AUV

Teledyne Gavia will introduce its new 6000 meter rated AUV --  SeaRaptor --  at Ocean Business 2019 in Southampton in April.SeaRaptor AUV incorporates a broad range of Teledyne content including acoustic modems, ascent and descent weight releases, a black box pinger locator, sub-bottom profiler (Teledyne Benthos), multi-beam echosounders, obstacle avoidance multi-beam sonar (Teledyne RESON), Doppler Velocity Log (DVL), Current, Temperature, and Depth sensor (CTD) (Teledyne RD Instruments), and onboard processing software (Teledyne Caris). In addition, the first vehicle delivered also

A System of Systems Approach to Mine Countermeasures

Z-Boat 1800 RP autonomous surface vessel (ASV), started the exercise by performing a bathymetric and LiDAR survey of the basin. Next, a Planck Aerosystems Shearwater unmanned aerial vehicle (UAV) conducted surface surveillance for both object avoidance and threat mitigation for the Z-Boat. A Teledyne Gavia autonomous underwater vehicle (AUV) then conducted a search-classify-map sidescan survey of the basin. Teledyne CARIS-Onboard, which was running on the Gavia AUV, performed mosaicing of the sidescan data in near real time while Charles River Analytics’ ATR software, also running in near

Teledyne Gavia Introduces ASW Training Target Module

Autonomous underwater vehicle (AUV) manufacturer Teledyne Gavia said it has recently delivered a Sonar Transponder Module (STM) for ASW training to an undisclosed military customer.The STM module made by Scanmatic AS of Norway and integrated into a Gavia payload module is capable of receiving and retransmitting sonar signals for training sonar operators. The STM consists of a flooded transducer compartment, an electronic compartment and a hydrophone that is towed behind the Gavia AUV. The STM is programmable to emulate different types of realistic submarine target characteristics including sizes and

New Slocum Glider Delivered to UC Davis

from the University of California, Davis and an international team of researchers on a collaborative study of ice / ocean processes in the region. Dr. Forrest's team, which includes the Korean Polar Research Institute (KOPRI), collaborated on a robotics investigation of the ice shelves using a Teledyne Gavia AUV from the University of British Columbia, and UC Davis' new Teledyne Webb Research Slocum glider.   The team deployed the AUV in an effort to map the bottom of the Nansen ice shelf while the Slocum glider "patrolled" in front of the ice shelf looking for evidence of fresh
