DVL-300-DR-FA4

Precisely measures the velocity of the equipment relative to the seabed.

Widely used on surface vessels, underwater towed bodies, AUVs, ROVs, etc., to achieve precise control and navigation.

Titanium alloy as standard across the full range, featuring smaller size, lighter weight and enhanced reliability.

Key Features: 300kHz Direct-reading DVL

  • Extended-Range Doppler Velocity Logging
    Designed for medium-depth underwater operations, offering reliable bottom tracking at greater altitudes, ideal for mid-range subsea vehicles and offshore missions.
  • High-Accuracy Navigation Performance
    Delivers stable velocity and altitude data with excellent cumulative precision, supporting accurate dead-reckoning and real-time position feedback for underwater robotics.
  • Robust 4-Beam Janus Configuration
    Classic 4-beam design ensures consistent and reliable data output, even in varied seabed conditions, sediment-laden environments, and dynamic flow disturbances.
  • Rugged Titanium Alloy Housing
    Corrosion-resistant titanium construction with multiple pressure ratings (1000m/3000m/6000m), built to withstand demanding offshore and deep-water subsea conditions.
  • Integrated Environmental & Attitude Sensing
    Equipped with precision temperature, pressure, and high-stability attitude sensors to maintain measurement accuracy under dynamic roll, pitch, and heading conditions.
  • Real-Time Data Output & Versatile Connectivity
    2 Hz update rate provides responsive velocity data, with RS-232/RS-422 interfaces for seamless integration with ROV/AUV control systems.
  • On-Board Storage for Mission Data
    64 GB Micro SD memory records full operational data, enabling post-mission analysis, validation, and performance review.
  • Efficient Low-Power Operation
    Optimized power consumption supports continuous operation on both tethered and battery-powered underwater platforms, suitable for extended subsea missions.
