Hi @dennysb, cool product - thanks for sharing! :smiley:

I’ve copied across a couple of photos to your post, so people can more easily decide whether they want to find out more.

Do you have some insight around which applications are likely to benefit by upgrading from standard side-scan or forward-scanning sonar to this new 3D option?

From a quick glance through your link it seems like there’s an upgrade option for existing Omniscan users, and there’s also compatibility with SonarView, which is good news for existing users! :slight_smile:

Hi @dennysb -
This is truly quite an exciting product! I’ve been excited to start evaluating one (last week was the first test) and look forward to offering an upgrade kit on the Reef for users who already have a pair of Omniscans. From what I understood, a more integrated version will be coming later this year (June-ish?) for users that without the Omniscan SS looking to have a bit simpler and more integrated system. The hardware to upgrade your Omniscan SS to Omniscan 3D is now available!

This truly is an incredible system, going from the <16 xyz points per ping to hundreds of points per ping, at 10 to 20 pings per second. It’s almost like your sidescans become multibeams! When logging the raw channel data, to maximize the data collected, this can result in quite a lot of network traffic - @ljlukis shared these values:
• Pi–>Host, Log Channel Data enabled: 22 Mbps
• Pi–>Host w/o Log Channel Data: 2.0 Mbps
Luckily, SonarView running on the pi means none of that traffic has to make it across the WiFi link to the BlueBoat- it is all logged onboard.

For any users looking to upgrade in the meantime - be aware that you’ll need a second ethernet switch, in addition to the first one you installed for the Omniscan SS. This is because each of the four Cerulean devices uses an ethernet connection, and you need a connection for both the Raspberry Pi and Mikrotik. Six ports is one more than the 5 the Blue Robotics switch has!

I installed a second switch in the port hull, connected both port devices to it, and ran a single ethernet cable through the cross tube to the primary ethernet switch. My configuration looks like this currently - sharing because the one in the docs seems to have only one transducer connected. I determined which MAC addresses of the units corresponded to which side of the vehicle through an in-water test - murphy’s law ensured the data was flipped, so I reversed the yaw values and was all set!

Yeah, thanks Elliot and Tony!

On the data bandwidth requirement, we mainly use the “channel data” for internal diagnostics and testing so in most applications this will not be required. Still, there is a lot of data. The 2Mbps per side is conservative I believe.

As for applications, anybody that really wants a full point cloud will benefit. It’s surprising how many customers ask if the normal OS450 SS sidescan makes a point cloud, so it seems like many people do! Certainly many people want to map aquatic vegetation, and while SS can do this to some extent, once you see the seaweed beds popping up in 3D, you have no doubt! I think in the kelp world it will be a game changer. Everybody seems to want to quantify biomass, and this is an area of active research where I think Omniscan 3D can play a key role.

And then there is 3D situational awareness. I think we’re only beginning to explore the benefits of 3D sonar deployed on ROVs.
