I currently have a Waterlinked USBL System with me. But whenever I test it out, I am getting a very huge drift in both x and y coordinates. It’s no way close to what I saw in BlueRobotics test tub where even Position Hold worked fine. I am trying to figure out the reason for drift.
I have some questions in mind.
On the surface, I have an onboard GPS. Does this get deactivated once I connect Water linked? Or does both work in tandem? (in surface only)
The waterlinked has two stickers to follow the coordinate system. One in the outside and one in the inside. I currently follow the one on the outside. Does this affect the location?
I am not getting proper depth output on Waterlinked from the ROV? Both are different readings. Why is that?
