Our Inertial Navigation Systems have been tested during a three-day lasting hydrographic survey in the Hamburg (Germany) port area. SBG Systems and MacArtney Germany GmbH equipped a survey vessel with a complete Multibeam Echosounder survey configuration and conducted various tests to show the performance of the SBG Inertial Systems in different challenging environments.
Test conditions
A Multibeam Echosounder (MBES) survey is a method used to map the underwater environment with high precision. This technology employs multiple sonar beams to create detailed, accurate maps of the seafloor, underwater structures, and other submerged features.
Raw INS data were logged in real-time and merged with MBES data from the RESON SeaBat 7125 within the acquisition software Teledyne PDS. Hydrographic data were post-processed and filtered with BeamWorx AutoClean, INS data have been processed using SBG Qinertia. The reference is the tightly coupled Horizon high-end fiber optic solution.
Thank you MacArtney Germany for their help.
Calibration procedure
Calibration based on motion and trajectory data of the SBG Horizon.
The interface includes the survey line, the computed bathymetry, quality indicating layers and topographic features.
Calibration reports
Calibration reports and advised mounting angles for each SBG Inertial System. Offsets for each sensor for the vessel configuration and the sensor setup have been measured during an alignment survey and evaluated.
