DP80 Doppler Log High-Precision Underwater Navigation System

The DP80 Doppler Log is a high-precision underwater navigation instrument based on the Doppler effect, designed for autonomous underwater vehicles (AUVs) and surface vessels. It provides real-time velocity and altitude-from-seabed measurements and can operate independently or integrate with inertial navigation systems for enhanced accuracy and reliability. Ideal for research, surveying, ocean exploration, and navigation support.
