    How the UAC-08160X-SE4T Works


    The UAC-08160X-SE4T is a deep-sea underwater acoustic communication system designed for reliable long-range data exchange in environments where radio frequency (RF) and optical signals cannot propagate. As part of the UAC-08160X series, this model is rated for 6000-meter operations, making it ideal for deep-ocean research, subsea monitoring, and offshore engineering applications.

    Signal Conversion & Modulation

    • Data from buoys, autonomous underwater vehicles (AUVs), remotely operated vehicles (ROVs), or seafloor sensor networks is first digitized.
    • The underwater acoustic modem then applies advanced modulation schemes such as MASS and SC-MPSK, encoding digital information onto acoustic carriers in the 8–16 kHz frequency band, optimized for deep-sea underwater communication.

    Transmission & Propagation in Deep Water

    • Once modulated, acoustic wave transmission is emitted into seawater, traveling distances of up to 10 km under optimal conditions.
    • Data rates range from 100 bps to 4 kbps, with a typical bit error rate around 10⁻⁴.
    • The SE4T operates in half-duplex mode, alternating between transmit and receive, ensuring stable and energy-efficient communication in challenging deep-sea environments.
    • Propagation is influenced by temperature, salinity, pressure, and multipath reflections from the seabed and surface. The system’s robust design and signal processing algorithms mitigate these effects for consistent performance.

    Reception & Data Recovery

    • Incoming underwater acoustic signals are captured by a hydrophone.
    • The system then demodulates the signal and reconstructs the original digital data, enabling reliable transfer of telemetry, commands, and sensor information in subsea communication networks.
    • Power management allows extended deployment, supporting autonomous operation for scientific missions and industrial monitoring.

    Operational Parameters & Deployment

    • Maximum working depth: 6000 meters, providing full coverage for deep-ocean exploration, subsea infrastructure, and offshore energy projects.
    • Interfaces: Standard RS-232, RS-485, and RS-422 serial connections for easy integration with existing underwater acoustic systems.
    • Power efficiency: Optimized energy consumption ensures long-term deployment in ocean observatories and seafloor monitoring stations.

    Typical Application Scenarios

    • Deep-ocean observatories and long-term environmental monitoring networks.
    • Subsea cable and pipeline monitoring in offshore energy operations.
    • AUV/ROV communication for control and data relay in deep-sea exploration.
    • Buoy communication systems for oceanographic data collection.
    • Offshore engineering projects including oil & gas, renewable energy platforms, and marine infrastructure.
