Automatic Transducer Testing System
We possess an Automatic Underwater Acoustic Parameter Measurement System, a comprehensive platform integrating high-frequency free-field calibration, low-frequency plane-wave testing, and precision spatial positioning.
Covering an ultra-broad frequency range from 5 Hz to 2 MHz, this system delivers precise, efficient, and automated measurement of electro-acoustic parameters and performance evaluation for underwater acoustic transducers, arrays, acoustic materials, and underwater acoustic devices.
It serves as critical infrastructure supporting R&D, metrological calibration, and quality inspection in underwater acoustic engineering.
Every transducer is accompanied by a corresponding test report, ensuring the accuracy of sonar systems from the source.

Our Mission
Connecting the Ocean
Through high-precision sonar and communication technologies, we bridge the gap between the deep sea and the surface, building stable and efficient data pathways.
Enabling Persistent Observation
With autonomous platforms such as AUVs and USVs, we enable long-term, real-time data acquisition even in the harshest marine environments.
Empowering Intelligent Decision-Making
Our data solutions support more accurate monitoring, analysis, and management of ocean environments.
Advancing Sustainability
We contribute to marine science, infrastructure protection, and environmental conservation by enabling responsible and sustainable use of ocean resources through technology.
Our Commitment
We are committed to advancing sonar and autonomous marine technologies through continuous research and development, delivering reliable performance in demanding ocean environments, providing responsive global support, and promoting innovation grounded in environmental responsibility.
Our Vision
We believe the future ocean will evolve into a “Digital Ocean”: an intelligent network formed by sensors, autonomous systems, and communication links that continuously provide actionable, decision-ready data. With our technologies, the ocean becomes not only an area of exploration, but a responsive and observable ecosystem capable of real-time monitoring and protection.
