The DP-D100B Doppler Velocity Log (DVL) is a high-precision underwater navigation sensor based on the Doppler acoustic measurement principle. The system measures three-axis velocity relative to the seabed or water column and provides real-time altitude measurement between the transducer array and the seabed.

The DVL can operate independently or integrate with Inertial Navigation Systems (INS) to enable sensor fusion, improving navigation accuracy and reliability for underwater platforms.

Operating at 330 kHz, the DP-D100B offers extended measurement capability for deeper water environments, making it suitable for integration into Autonomous Underwater Vehicles (AUV), Remotely Operated Vehicles (ROV), Unmanned Surface Vessels (USV), and marine robotic systems requiring stable velocity and positioning data.
