Doppler Velocity Logger

[sudheeshk]

can anyone help me find information about Doppler Velocity Logger(DVL), which is better for ROV navigaton I think.

thank you

Hi @sudheeshk,

There are a few existing topics on the forum that may help:

Low cost DVL for subsea navigation and merge with INS

Hello - I’ve looked for low-cost DVL solutions to merge into an INS for an AUV mapping project. Curious if there is a project out there I haven’t found, or a group of people that are looking to bring something to market? Open source solutions don’t seem to have anything on it. Large corps have extremely costly solutions. Is there anything in the hobby/light industry space that’s pushing some of the big players out? Thanks!

ROV and AUV Localization an Introduction

Hey Blue Robotics Community! Relatively frequently I see people asking about, hovering, dead reckoning, and using GPS or IMUs for localization. This is often enough I think perhaps it would be useful to have a small guide on localizing underwater vehicles. This a first draft and should be considered an introductory guide. Any comments, criticisms, or things that I left off are welcomed and appreciated. Why is localization a problem for underwater vehicles? In the field of in air robotics, lo…

“I am working on a university project involving an INS/DVL navigation system, and I am looking for an affordable Doppler velocity sensor that would be suitable for this application. I need recommendations for a model that offers good accuracy for a navigation system. The maximum depth for testing will be between 30 to 50 meters.”

Let me know if you’d like any further adjustments!

Hi @hosseini -
Welcome to the forums! Besides the Watrlinked DVL a50, Cerulean Sonar has the Tracker 650 which we’re currently evaluating for the Reef.
