MDC presented in-depth QINSy drill-string training to five De Beers Marine Namibia surveyors. During the concentrated 3-day classroom work sessions, the DBMN surveyors were be guided through the basics of Navigation and Geodetics, Sonar Theory and typical survey hardware including GPS, Tide Gauges, Motion Sensors, Gyros, Sound Velocity Probes, Single Beam Echosounders, Multibeam Echosounders, ROV’s and subsea positioning systems. Trainees were shown how to interface these hardware devices and setup these devices in QINSy. Trainees were also be shown how to import background survey design raster and vector data into QINSy, survey planning, acquisition, data QC/QA and data processing.
