NavQuest Doppler Velocity Log（DVL）

LinkQuest's Acoustic NavQuest Doppler Velocity Log（DVL） is a high-precision underwater navigation and positioning system.

Product Description The acoustic NavQuest Doppler Velocity Log（DVL） uses LinkQuest's leading acoustic Doppler technology and low-power DSP technology to measure speed quickly and accurately, with longer working distance and less height limitation than similar products. The series of products can also seamlessly integrate TrackLink series ultra short baseline positioning system with PinPoint LBL positioning system. It is the best choice for underwater robots, underwater drones and other applications that require accurate navigation and positioning.
