Product Description
The DP100B Doppler Log uses the Doppler effect to provide real-time velocity and altitude-from-seabed measurements for underwater and surface vehicles. It can operate independently or integrate with inertial navigation systems to enhance navigation accuracy and reliability. Ideal for AUVs, surface vessels, research, and underwater surveying applications.
