Vessel Navigation Aids


Sonardyne’s Navigation and Obstacle Avoidance Sonar (NOAS) has been developed to meet the demand for an integrated forward look navigation and obstacle avoidance sonar that aids navigation in poorly chartered areas, or where there is the potential to encounter underwater obstructions.

NOAS scans the water column ahead of the vessel and images the sea bottom. This information is represented in a 3D graphic display so the vessel pilot can steer a safe course. Finally, when the vessel is stationary, NOAS has an intruder detection mode to protect the vessel against diver attack.
