The PA series is a new compact Doppler velocity log. It adopts mature phased array technology and advanced bottom-tracking algorithms, and can be used for acoustic navigation when carried by AUVs or ROVs. The PA series DVL features a split structural design, high precision, small size and light weight, no need for sound velocity calibration, and can be widely applied in marine engineering.
