NORBIT DCT – Hydrographic Survey Made Easy

maps even without the internet access.Quality-driven mission executionDCT offers four types of real-time display accessible via simple tap or mouse click under the layer menu button. These are depth, standard deviation, sounding density and backscatter. The depth by default is simply the depth from the sonar to the bottom and can be displayed in a projected reduced chart datum as well. The standard deviation and sounding density are produced per given grid size. By default, 0.5m grid size is selected but can be changed by the user. The backscatter is given as average intensity from each grid cell.All

Kongsberg Inks First Deal for HUGIN Superior

will be delivered in DNV certified offshore containers along with a portable version of Kongsberg’s HiPAP 502 acoustic positioning system for easy mobilization onboard vessels of opportunity.The HUGIN Superior is equipped with the new HISAS 1032 Dual Receiver interferometric synthetic aperture sonar (SAS), which doubles the area coverage rate of previous systems and provides high resolution imagery and bathymetry data products. A redesigned processing toolchain reduces the time-to-data and provides full featured in mission processing capabilities. The AUV system also includes the de facto industry

that required multiple instruments to be deployed.”For this particular survey, and in order to precisely measure and characterize the site of the future Groix & Belle-Île pilot wind farm, iXblue is using an multibeam echosounder (MBES) for high resolution bathymetry, a towed side-scan-sonar for seafloor nature identification, a magnetometer for object detection, a sparker for sediment thickness, as well as iXblue’s own sub bottom profilers, the Echoes 3500 and 10 000, and Gaps pre-calibrated ultra-short baseline (USBL) system to get precise positioning of the collected data from

Kraken Tallies $2.1 Million KATFISH Order

company specializing in the design, integration, and operation of autonomous maritime systems, will deploy Kraken’s KATFISH 180 as part of its SeaScout expeditionary system for seabed mapping and intelligence.Kraken’s KATFISH 180 is an actively stabilized towfish with synthetic aperture sonar (SAS) providing wide area seafloor survey, with area coverage rates (ACR) of 3km2/hour and up to 8 knots tow speed; superior pixel resolution for detection and classification (3cm x 3cm @ > 200m per side range); real-time, full-swath, full-resolution SAS processing; 200m+ operating depth; altitude-

Offshore Survey Vessels: Ready for Faster Sensors

and, therefore, we are immersed in a community which is hell-bent on developing the latest and greatest (sometimes not) ocean technology. We see it, mobilize it, launch and recover it (if all goes to plan) and evaluate its effectiveness for commercial use.  AUVs, towed robotics, synthetic aperture sonars, multi beams, acoustic sources, acoustic arrays, mine hunters, submarine hunters, oil hunters, fish trackers, ROVs, drop cameras, UxVs; the list is endless, and we love every second of it.In light of that, I can postulate over this robotics conundrum with a reasonably experienced and increasingly

US Navy to Evaluate Kraken's AquaPix MINSAS

Office. The FCT is designed to test selected foreign technologies as evaluated by U.S. military operators, with a view to future procurement.Under this contract, Kraken will integrate its AquaPix MINSAS sensor on a man-portable AUV owned by the U.S. Kraken’s AquaPix MINSAS synthetic aperture sonar (SAS) sensor is currently offered in the MINSAS 60, 120, 180, and 240 configurations and has been traditionally integrated to medium- and large-size AUVs and towfish. As part of this FCT contract, Kraken will optimize the MINSAS 60 sensor making it better suited for small, man-portable AUVs while

There’s also a through moon pool-based handling system for recovering the AUV on deck, safely.The system will support subsea survey in shallow waters as well as in deep and ultra-deep waters, operating a wide variety of payloads ranging from more conventional types such as side-scan sonar and multibeam echosounders to more advanced such as synthetic aperture sonar.uSEA is looking for partners to complete the qualification programme, which is expected by the end of next year (2020). After that, the company is targeting operations in the sea and it’s looking for pilot projects

moved into the new location and will continue to build the firm’s Tentacle Winch and Autonomous Launch and Recovery Systems there. The facility will also be used to field test and support Kraken’s various underwater robotic platforms, including the KATFISH high speed towed synthetic aperture sonar (SAS) system and the THUNDERFISH autonomous underwater vehicle (AUV). Kraken has also installed a dockside remote operations container which is available for use by COVE residents.Unmanned maritime vehicles (UMVs) are robotic systems which operate both below and above the surface and without an operator
