We recently did some tests with the BlueROV2 with a Tritech Micron Scanning Sonar. It’s a mechanical scanning sonar that provides a 360 degree picture of features around you underwater. Here’s a video of the test:
The sonar was integrated through an extra twisted pair in the tether using RS485. We used the Tritech software on the surface to view the data.
Here’s a few take aways for us:
- We’ve tested a few scanning sonars and this one definitely provides the cleanest image and least noise.
- We were able to find a bunch of objects on the bottom that were detected by the sonar (tire, ropes, scrap, another ROV)
- It was incredibly useful for navigation purposes. With the sonar and compass, we could “fly by instruments” and navigate easily, using the dock pilings for reference.
