5 Experimental Research
The designed system prototype was installed and used in the Klaipeda university
ship. The measurement was carried out when the weather conditions were
favourable for working at sea. The direction of wind was variable from 1 to 2 m/s,
the height of the waves was from 0.3 to 0.5 m and the sip used an
”
side view sonar system. For a proper research of the seabed the ship movement has
to be at least 4 knots (about 2.06 m/s) (the data foundation of CORPI). During the
research, the speed of the ship was 10 knots (about 5.14 m/s).
