The software combines USV control, multibeam sonar control and data acquisition in one. In addition to navigation, it provides control of multibeam surveys, real-time display of water column images and coverage maps (up to a 0.1 m grid), fast export of bathymetric results and system alarms. It is operated from an Android remote controller with a 7-inch display (1920×1200), 3 km control range and 10 hours of endurance. The Dimai CC platform enables instant command and field monitoring.
