Validation of a new generation DVL for underwater vehicle navigation

Nortek has developed a new Doppler velocity log (DVL) based on a novel bottom detection principle. This allows for the ability to estimate individual beam and ping Doppler measurement noise in real time. Another capability that has been embedded in the new DVL is an accurate timing reference of the velocity estimate. Using the Kongsberg Maritime (KM) HUGIN autonomous underwater vehicle (AUV) as testbed, we present in this work sea trial results for the new Nortek DVL.
