About DVL A250

DVL A250 uses four acoustic beams to measure vehicle velocity relative to the seabed across altitudes from 30 centimetres to 250 metres. It maintains bottom lock at speeds reaching 15 metres per second and provides velocity input for subsea navigation and station keeping.

The 149-millimetre-diameter unit weighs 1.65 kilograms in air and is offered with 1,000- or 4,000-metre depth ratings. Ethernet and serial interfaces support Water Linked APIs and PD-compatible outputs. An onboard computer, AHRS assistance and compact housing simplify ROV, AUV and USV integration.
