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.
Applications
The DVL-600K-Phased is a compact, phased-array Doppler Velocity Log designed for precise underwater navigation and bottom tracking. With its lightweight design, low power consumption, and high-accuracy velocity measurement, it is ideal for integration into AUVs, ROVs, and USVs. Supporting multiple depth ratings (300 m / 3000 m / 6000 m), the DVL-600K-Phased provides reliable performance for both shallow-water and deep-sea missions.
- Autonomous Underwater Vehicles (AUVs)
Compact and large-diameter AUVs, providing precise bottom velocity and altitude measurements for navigation and path control. -
Remotely Operated Vehicles (ROVs)
Inspection-class ROVs, delivering accurate bottom tracking and altitude data in near-bottom or confined environments. -
Uncrewed Surface Vessels (USVs)
Surface platforms, offering reliable speed-over-ground and drift compensation when GPS is unavailable or degraded.
