Hi all,
I am trying to use the cerulean surveyor MBES to build a model of a lagoonal coral reef we are surveying. However, I am encountering some issues and am wondering if they are simply because of interference from itself where I am using it (shallow water, enclosed lagoon) or if something is going wrong.
It seems when I turn it on, it is a luck of the draw whether it shows me accurate depth or not - once it is showing incorrect depth, I have to close/reopen the session a handful of times until it works again. The depth isn’t just slightly out - it is going to 90-120m, when we are in depths of 1-10m. When this happens, the points are scattered all over the place and are definitely not gps accurate. I have attached an image showing a run which I thought was successful and I had rectified the issue until it suddenly started showing points at 120m depth, where I ended the run. You can see these scattered well away from where the boat was actually surveying. When I restarted the connection to the surveyor it could not obtain accurate depth and was reading 100m depth pings
If I turn off auto range the boat appears very far off centre in the sonar view panel and is positioned well below the range limit
I have updated my ardupilot, sonarview, recalibrated my surveyor on a level surface, remade the session following the docs and disconected/reconnected all surveyor connections as part of my trouble shooting process.
Any ideas?
Thanks in advance
