will be added to the current Gavia AUV fleet, which has been operated by the Polish Navy for Naval Mine CounterMeasures (NMCM).To complement the Gavia AUVs previously procured, the acquisition will include all required topside equipment, as well as the AUV operation and maintenance training.In 2014, Teledyne Gavia completed a competitive tender process for the delivery of the first MCM AUVs for the Polish Navy, winning the contract on the basis of best value with conformance to the required functional and technical requirements. Based on the Polish Navy’s experience, the Gavia AUV has been selected

Survey work close to the edge of glaciers can be too dangerous for a survey ship because of the falling, or calving, ice.Using a Teledyne Gavia, the ship doesn’t have to go close. In 2016-2017, SAMS used a Gavia, called Freya, to do just this in Svalbard. There, it was able to survey seabed previously hidden by the now retreating glacier. Photographs, sonar images and crucial oceanographic information were gathered to help scientists

SeaRaptor AUV Completes Sea Acceptance Test

Teledyne Gavia, a company of Teledyne Marine, announced it has completed the sale and recent sea acceptance testing of the SeaRaptor, 6,000m rated autonomous underwater vehicle (AUV). The client was not disclosed.The 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

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.

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
