What are the maximum and minimum speeds that the DVL can detect?
Maximum velocity for the Workhorse Navigator is 10m/s (19.4 knots) with beam 3 pointing forward. However, by rotating the transducer head by 45° this can be increased to 14m/s (27.2 knots). RDI can provide custom units capable of detecting higher velocities on request. Minimum velocity is zero, which allows you to use it for station keeping (hovering). The DVL is able to provide high-resolution data at very low velocities. At altitudes of less than 4m from the seabed a special low altitude bottom tracking mode turns on automatically.
