Nice promo video!
Awesome! Great work Dennys!
Hi There!
I am very interested of Omniscan 450 fs. To install it to my ROV. What I need is coordinates to objects that I can find. What I can not find, is that if I invest to Omniscan 450 and lets say DVL. Am I able to pickup coordinates to the objects?? And if so how accurate are those coordinates 3m-20m??. Anyway I have been working a long time with sidescan sonar like Marinesonic, Klein, Deepvision, Tritech and some others. So I know something with that side and how to operate them. Now I need to go very difficult places like in this video, but much deeper and there is some man made objects that need to pick up. That’s why I am asking. I have Nido w/8 thrusters. about same as Bluerov2 w/8 thrusters. Anybody able to help me??
Thank you and have a nice day
Hi @Rauno -
Welcome to the forums!
To get coordinates for the objects you scan with the Omniscan FS, you’ll need to provide a position source to the vehicle. A DVL does allow the vehicle to hold position, and tracks the relative position, but to give it a global reference you either need to tell the vehicle an initial GPS location (possible via manual entry, typically) or use a USBL/LBL device like Cerulean’s ROVL (convenient in new omnitrack form factor) or WaterLinked’s Underwater GPS. Both are supported by the BlueROV2 running BlueOS - I’m not certain what level of compatibility these systems would have with your Nido!
Your initial position estimate would could have an accuracy dependent on whatever GPS you use and how it’s positioned relative to the ROV when the position is set, whereas the acoustic systems with integrated surface GPs typically give ~1m accuracy.
That’s such a cool video @dennysb! Don’t know how I didn’t see it before.
And we should add support for changing the vehicle image so you can add your color scheme as well

Thank you Tony.
Nido is same Rov as Bluerov w/8 thrusters. The company doesn’t exist anymore, but is good rov like Bluerovs. Do you know how does 2 unit OS450FS can give the position and the image in the same time? I mean what is needed to do that? Or is it better with one OS45FS unit and DVL? Does it really work like that??
Regards
Hello,
Omniscan pings interleaving “imaging pings” and “Doppler pings.” “Imaging pings” are the normal pings Omniscan uses to generate the sonar image. The “Doppler pings” are not suitable for imaging, but with special processing of the return echo. With this approach, Omniscan can produce an estimate of the velocity relative to the ping direction.
A DVL device, such as the Tracker 650, will deliver better overall performance.

Ok thank you, we will invest to Tracker 650
