The acquisition is in line with Sea-scape?s continued growth in the South- east Asia Region where their main oper- ations are in Indonesia, with other areas including Thailand and Timor Leste Australia. The 1,000-m-rated Tiger has a proven pedigree in the oil and gas in- dustry, where operators value its maneu- verability inside structures and its ability to cope with strong currents. Despite its compact size, a range of sonars, cameras and tools can be added as needed to un-dertake a wide scope of tasks. Supply- ing the Tiger was Singapore-based Saab Seaeye distributor, Oceanvision. Polish Forces Take Delivery of Teledyne Gavia AUVs Teledyne Gavia completed a contract with the Armament Department of the Polish Ministry of Defense for the de-livery of two Gavia Defense AUV sys- tems for mine countermeasures (MCM). The provision includes all required top- side equipment and AUV operation and maintenance training. Teledyne Gavia completed a competitive tender process for delivery of the  rst MCM AUVs into Poland, winning the contract on the ba-sis of best value with conformance to the required functional and technical parameters. The Gavia vehicles deliv- ered are equipped with the EdgeTech 2205 side scan sonars. The simultane- ous dual frequency 600/1,600 kHz Ed- geTech 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  ve knots. The ad- dition 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 coun- termeasures (MCM) and search and salvage operations, in continental-shelf waters and beyond. The Polish Armed Forces also pur- chased SeeTrack Military software from SeeByte Ltd. The SeeTrack Mili- tary MCM Evaluator software package includes all core MCM options: PMA Automatic Target Recognition; Sea oor Classi cation; 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  eet of Ga- via 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 special- ists from four District Military Divi- sion (Gdansk).
