Kongsberg DAS Dual-Axis Scanning Sonar

Kongsberg DAS Dual-Axis Scanning Sonar

A rugged and reliable long-term solution for seabed and structural monitoring.

The DAS (Dual-Axis Scanning Sonar) is a profiling scanning system designed specifically for long-term marine monitoring. It features strong environmental adaptability, operating stably in high-current and harsh marine conditions, making it an ideal tool for long-term dynamic monitoring of the seabed or underwater structures.

The DAS can operate in conjunction with MS1000 software or function in an "Autonomous Mode" to collect data independently, transmitting it back to shore via cable or wireless telemetry. Its continuous 3D scanning capability accurately captures dynamic changes in sediment scour and deposition. The output 3D point cloud data stream (X, Y, Z coordinates) is directly compatible with various digital terrain modeling software, facilitating high-precision topographic map generation and analysis.
