DVL-600K Phased-Array
Phased-Array Doppler Velocity Log 600kHz
The DVL‑600K‑Phased is a high‑performance 600 kHz phased‑array Doppler Velocity Log (DVL), engineered for underwater and surface unmanned platforms including AUVs, ROVs and USVs. Optimized for high‑precision navigation and velocity measurement in shallow‑to‑moderate water depths, it features core advantages of phased‑array beamforming technology, millimeter‑level measurement accuracy, and a compact low‑power design, serving as a critical navigation sensor in GPS‑denied underwater environments.

Overview
System Composition
The DVL-600K-Phased Doppler Velocity Log consists of two main components: the phased array transducer and the electronic chassis.
- Phased Array Transducer (waterproof): Responsible for receiving velocity-sensitive acoustic signals to achieve precise velocity measurements.
- Electronic Chassis (non-waterproof): Handles signal preprocessing, acoustic signal analysis, velocity computation, and acoustic transmission.
In practice, the electronic chassis is typically installed in the dry compartment, while the transducer is mounted in the wet end, implementing a dry/wet separation design for easier system integration and maintenance.

Specifications
Full Array Directivity of Transducer
Each DVL transducer undergoes impedance and electroacoustic performance testing prior to factory delivery. We operate an in-house underwater acoustic laboratory and test tank. The test scope covers impedance, directivity, transmitting voltage response and receiving sensitivity.
The transducer directivity data shown below is from one of our test samples, for reference only.
