DVL-Hover-H1000 
Underwater Anti-Current Hover Navigation Sensor​

Light Weight & Low Power Consumption;  Compatible with Small-Size ROV / AUV

Improve the engineering operation capability of compact ROV / AUV

Water tracking: Not available

The DVL-HOVER-H1000 is a compact Doppler velocity log designed for subsea platform operators requiring reliable bottom-track velocity, altitude measurement and anti-current station-keeping capability.


Integrating advanced broadband signal processing, high-precision acoustic transducer design and low-power mixed-signal circuitry, this embedded DVL delivers stable measurement performance in demanding subsea environments. Its 90 mm compact diameter enables flexible integration into space-constrained underwater vehicles.


Overview

DVL-HOVER-H1000 Doppler velocity log

Key Feature​s

  • ±0.4% ±5 mm/s Velocity Accuracy 
    High-precision bottom-track velocity measurement supports accurate vehicle motion control and long-term station keeping.
  • <5 cm Acoustic Blind Zone 
    A very short blind zone allows ROVs and AUVs to operate closer to the seabed, supporting high-resolution inspection and close-range intervention.
  • 90 mm Compact Diameter 
    With a compact 90 mm diameter, it is particularly suitable for small-sized ROVs and space-constrained subsea platforms.
  • Lightweight & Low Power Consumption
    Lightweight construction and low power draw help underwater vehicles reduce payload impact and extend mission endurance.
