www.sea-technology.com August 2015 / st 41 T he acquisition of QPS by Saab created the possibility for closer integration between the Saab AUV platforms and the marine spatial data software solutions from QPS. This resulted in a joint project in 2014 to demonstrate a high-end survey system that was capable of very accurate, combined sonar, multibeam bathymetry, video and sub-bottom profl- ing. The system is based on Saab's hovering AUV capable of very stable, autonomous, close-up scanning of both structures and bottom features. The QPS data acquisition software ensures that all data are collected together with navigation data in an optimal way for precision and further processing. The result is merged, high-quality data that are easily evaluated and exported. Sabertooth The Sabertooth hybrid AUV is based on technology coming out of the Saab Double Eagle and SAROV vehicles, as well as components from the commercial ROV range. The result is a vehicle that is very quiet and stable with advanced autonomy. The Saber- tooth is also extremely fexible in that it is able to operate in various modes, such as tethered mode, acoustic mo- dem mode and autonomous mode. Software Tools for Survey Data Acquisition, Processing QPS offers a suite of software prod- ucts for survey data acquisition, processing, analysis and presentation. QINSy is the data acquisition software used in the hydrographic and marine geophysical industries for more than 20 years. Qimera is the brand new data processing pack- age. Fledermaus is an industry standard for 4D data analysis, visualization of and data management via close GIS links. Integrated Survey System The following sensors were integrated for the trials, which took place at Lake Motala in Sweden in August and September 2014: R2Sonic 2024 MBES (bathymetry, back- scatter and water column), EdgeTech 2200 combined SSS and SBP, Teledyne BlueView M900-2250 imaging sonar, Tri- tech parametric SBP, Phins III INS with RDI DVL, and AXIS industrial-grade HD IP camera. Data Workfow QINSy is tightly coupled with the Sabertooth vehicle control system (ICON), and this allows the QINSy system Seabed Surveys Using Sabertooth AUV With Spatial Data Software Combining Sonar, Bathymetry, Video and Sub-Bottom Profling Data By Jan Siesjö • Frans Nijsen (Top) Sabertooth with the survey sensors installed.
