Product Introduction
Doppler Velocity Log (DVL) – High-Precision Commercial Grade The DVL A50 is the world’s smallest Doppler Velocity Log (DVL). Leveraging cutting-edge technology, the A50 combines an ultra-compact form factor with low cost and exceptional performance. By providing highly accurate velocity-over-ground data, the A50 enables ROVs, AUVs, and divers to achieve superior precision and stability in navigation, even when operating in dynamic environments characterized by strong currents and complex terrain. |
