Underwater Vehicle - NOAS

NOAS FOR UNDERWATER VEHICLES

Designed for use on manned submersible and swimmer delivery vehicles (SDVs), NOAS enables faster, safer and more efficient navigation by detecting potentially hazardous underwater obstacles in their path. In 2D mode NOAS provides the crucial long range navigation information enabling underwater vessels to steer a safe course. When combined with its 3D capability, the sonar scans the water column to provide more detailed detection of obstacles, and mapping of the seabed in front of the vessel.
