Teledyne Gavia announced that it has completed a contract with the Armament Department of the Polish Ministry of Defense for the delivery of two Gavia Defense AUV systems for mine countermeasures (MCM). The provision includes all required topside equipment and AUV operation and maintenance training. Teledyne Gavia completed a competitive tender process for delivery of the first MCM AUVs into Poland, winning the contract on the basis of best value with conformance to the required functional and technical parameters.

The Gavia vehicles delivered are equipped with the latest EdgeTech 2205 side scan sonars (Edgetech, West Wareham, MA). The simultaneous dual frequency 600 /1600 kHz EdgeTech 2205 side scan sonar and the Kearfott T24 inertial navigation system (INS) allow the Gavia to gather high resolution, accurately navigated, sonar images while remaining submerged for several hours of continuous operation at survey speeds up to five knots. The addition of a high accuracy GPS and the augmentation of the INS by Long Base Line (LBL) beacons ensures precise navigation during even longer duration and deeper missions. This combination of sensors make it ideal for mine countermeasures (MCM) and search and salvage operations, in continental-shelf waters and beyond.

The Polish Armed Forces also purchased SeeTrack Military software from SeeByte Ltd. (Edinburgh, Scotland). The SeeTrack Military MCM Evaluator software package includes all core MCM options: PMA Automatic Target Recognition; Seafloor Classification; Change Detection; and SeeByte's Performance Analysis and Training Tool. The software provides a solution for rapid on-site analysis and fusion of sensor data for the fleet of Gavia AUVs, rapidly generating targeted information from the AUV data.

The sea acceptance trials took place at the Teledyne Gavia proving grounds near Kopavogur, off the west coast of Iceland. The tests were supervised by representatives of the Polish Navy, and the results were checked by specialists from 4 District Military Division (Gdansk). Data analysis during the SATs and training confirmed the vehicle performance and suitability for MCM search, location and identification missions.

The vehicles were supplied through Enamor Ltd. (Gdynia, Poland), Teledyne Gavia’s official representative in Poland. Enamor is a research and production company focused on new technology and active in many projects in Poland in the fields of navigation, communication, hydrography and automation.

The Gavia Defense AUV has a low-logistics, fully modular design. This facilitates rapid transport and maintenance, and is designed to increase operational availability and reliability. Each Gavia can also be equipped with a variety of additional sensor modules. This creates an asset which can be configured for MCM, search and salvage or hydrography missions, without needing to be dedicated to just one task. In the future, the AUVs delivered in Poland can be equipped with modules for multi-beam bathymetry, sub-bottom profiling, or even submarine emulator sonar training targets.

This contract marks the first purchase of AUVs for MCM by the Armed Forces of Poland. The knowledge gained from operating the Gavia AUVs will help develop the concept of use of AUVs in the Polish maritime theatre. Significant benefits are expected from a low-logistics AUV asset that can carry out both MCM and hydrography missions.
