Doppler Velocity Log (DVL) | High-Precision Underwater Navigation for AUVs & Marine Vessels

Product Overview

The DP-D100B Doppler Velocity Log (DVL) is a state-of-the-art underwater navigation instrument utilizing Doppler effect technology for precise measurement of 3D velocity and bottom-altitude. Designed for Autonomous Underwater Vehicles (AUVs), surface vessels, and marine platforms, it delivers real-time navigation data, either as a standalone system or integrated with an Inertial Navigation System (INS) to enhance accuracy and reliability in challenging underwater environments.

Key Features

• High-Precision Measurement: Velocity accuracy better than 4‰ ± 2 mm/s; depth measurement error 1% ± 1.2 m.
• Extended Depth & Speed Range: Measures speeds from -15 kn to +15 kn; operates at depths from 2 m to 170 m.
• Durable & Pressure-Resistant: Rated for 3.6 MPa water pressure.
• Low Power Consumption: Average ≤25 W; peak ≤140 W.
• Compact & Modular Design: Lightweight (≤1.6 kg) electronic unit and transducer, easy to install and maintain.
• Reliable Communication: Supports RS422 and dual RS232 interfaces with RDI PD6 protocol, providing fixed-length, verified ASCII data.

Core Functions

1. Real-Time 3D Velocity Measurement: Accurate X, Y, Z-axis speed data for precise navigation.
2. Bottom-Altitude Sensing: Measures vertical distance to seabed for safe AUV operation.
3. Self-Diagnostics & Status Monitoring: Tracks transducer depth, system health, and operational status.
4. Seamless Data Integration: PD6-compatible output ensures easy interfacing with computers, INS, or mission control systems.

Advantages

• High Reliability: Fully sealed, waterproof design for extended underwater use.
• Easy Operation & Maintenance: Quick installation, configurable transmission settings, and intuitive monitoring.
• Flexible Deployment: Operates standalone or combined with INS and marine navigation systems.
• Robust Environmental Adaptation: Works in -10°C to +50°C; storage -40°C to +70°C, suitable for diverse marine environments.
