High Light High Accuracy Doppler Velocity Log DVL3D Speed Doppler Velocity Log DVL

The DP500 Doppler Velocity Log (DVL) is a high-precision underwater navigation instrument designed for Autonomous Underwater Vehicles (AUVs), Remotely Operated Vehicles (ROVs), and research vessels. Utilizing the Doppler effect, it provides real-time 3D speed measurement and altitude-from-bottom measurement, offering reliable data for navigation, positioning, and underwater research.

The DP500 features fast startup, a long-term internal data logger, and customizable depth capability, and can be integrated with inertial navigation systems for enhanced navigation accuracy. Its robust design ensures performance even in challenging marine conditions.

Technical Specifications

Performance:

  • Center Frequency: 150kHz ±1kHz
  • Input Voltage: 44VDC~52VDC (Nominal 48VDC)
  • Velocity Range: -15kn to +15kn
  • Velocity Accuracy: ≤2‰ ±2mm/s (@ flat sediment bottom, sea state ≤3)
  • Maximum Bottom Tracking Depth: 500m
  • Minimum Detectable Depth: ≤4m
  • Maximum Operating Depth: 1000m (customizable)
  • Time to Valid Output: ≤45s
  • Internal Data Logger: ≥312 hours

Mechanical & Dimensions:

  • Electronics Chassis: ≤300mm × 230mm × 160mm
  • Acoustic Transducer Array: ≤Φ220 × 80mm
  • Electronics Chassis Weight: ≤16kg
  • Transducer Array Weight: ≤12kg (including water-proof cable)
  • Installation Interfaces: Chassis 242mm × 180mm; Transducer 7 × M8mm

Interfaces:

  • RS422 output for velocity and depth
  • Data download interface for mission data
  • Power input via XS4 connector: 48VDC
  • Communication protocol: BI/BD/WI/WD formats (see attachment)

Advantages

  1. High Accuracy & Reliability – Velocity accuracy ≤2‰ ±2mm/s ensures dependable measurements.
  2. Rapid Deployment – Valid speed data output within 45 seconds.
  3. Deep-Water Capability – Supports up to 1000m depth for flexible marine applications.
  4. Long-Term Data Logging – Stores over 312 hours of mission data internally.
  5. Easy Integration – Standard RS422 and mechanical interfaces for AUV/ROV systems.
  6. Robust & Durable – Waterproof and pressure-resistant, ideal for harsh underwater environments.

Application

  • Autonomous Underwater Vehicle (AUV) navigation and speed tracking
  • Remotely Operated Vehicle (ROV) altitude and velocity measurement
  • Oceanographic research and seabed mapping
  • Underwater engineering surveys and environmental monitoring
  • Deep-sea exploration and scientific missions
