Hi everyone.
I want to conduct a bathymetric survey in the Dam area, but there are solar panel covering the surface of the Dam. Therefore, I think the ROV is a solution for this case. is it possible if I configure the MBES/SBES for bathymetric data? any recommendation for the positioning system?
Thanks!
Hi @Kilatbesihitam666 -
That sounds like a tricky problem! You’re going to lose quite a lot of positional accuracy by relying on acoustic systems to locate an ROV performing a survey (vs. GPS at the surface.) Is there no way for a surface vehicle like aBlueBoat to navigate between or underneath the panels?
Otherwise, a acoustic localization system from WaterLinked or Cerulean Sonar may be worth looking into, but if you have stringent accuracy requirements, it may not be possible to meet them…
Hi Tony!
Thank your for answering my question. unfortunately there is no way for the surface vehicle to navigate. can you tell about the working system of the WaterLinked and Cerulean if it configured to BlueROV? how about the accuracy of these two positioning system?
thank you
Hi @Kilatbesihitam666 -
Those are better questions for the vendors that make those products! Checkout the Cerulean Omnitrack, or the Water Linked UGPS (purchase link)
These devices put a pinger on the ROV, and have topside acoustic equipment estimate its position. This is combined with the GPS position of the topside, and sent to the vehicle autopilot. With this position source, collected sonar data becomes geo-referenced, and auto missions are also possible.
