How a vessel-mounted ADCP helps keep a Dutch navigation channel open
I am deploying my ROV into unknown subsea conditions. How do I ensure operational safety and efficiency?
"We needed high navigational accuracy, and knew DVLs could provide this from our background in #subsea,” says Amy Underwood, Senior Roboticist at @Squarerobots. Read more: #Nortek #DVL #technology #ROV #AUV
