Multibeam Echosounders
Discover cutting-edge solutions from 10 leading global suppliers
Hydro-Tech has launched the MS400C, the first fully integrated multibeam echosounder of its kind.
Designed to streamline operations and enhance efficiency, the MS400C consolidates a sonar processor, Inertial Measurement Unit (IMU), Global Navigation Satellite System (GNSS), and Sound Velocity Sensor (SVS) into a single, compact sonar head. This innovative design transforms multibeam deployment, particularly for small Unmanned Surface Vehicles (USVs), reducing complexity and improving operational flexibility.
The MS400C eliminates the need for a separate sonar processor, simplifying installation and reducing potential points of failure. Deployment is straightforward: mount the sonar head to the Unmanned Surface Vehicle, connect the power and data cables, and link the GNSS antennas. This integrated approach minimizes installation errors, shortens setup time, and reduces the need for extensive operator training. Additionally, its compact design optimizes space within the USV’s waterproof compartment.
Traditional multibeam systems often struggle with overheating, especially in harsh environments. The MS400C overcomes this challenge by housing all critical components—including the sonar processor and IMU—within the sonar head, which is continuously cooled by surrounding water. This eliminates exposure to direct sunlight and ensures stable, long-term performance, even in extreme heat conditions.
The MS400C is engineered for effortless deployment. All positional relationships between the IMU, transducer, and GNSS antenna are preconfigured in the software by the USV manufacturer. Once in the field, operators can complete setup within minutes and initiate surveys using the Auto Survey function. The system intelligently adjusts working parameters based on environmental conditions, removing the need for manual calibration and significantly boosting efficiency.
With integrated real-time roll stabilization, precise vessel attitude measurements, and accurate sound velocity corrections, the MS400C delivers high-resolution depth data with exceptional reliability. Its lightweight yet powerful design makes it an ideal solution for inland hydrographic surveys and demanding bathymetric applications.
