Inquiry about mini ROV localization solutions

Hey, BlueRobotics Community!

I’m a newcomer here and I’ve been exploring some discussions on IMUs, EKF, and related topics. I’m particularly interested in mini ROVs and their localization systems. I’ve come across discussions touching on these aspects, but I’m uncertain if there’s already a solution for underwater localization.

Could someone please guide me or share insights if there’s an existing implementation or ongoing discussions regarding mini ROV localization? I’d greatly appreciate any information or pointers you can provide.

Thanks a bunch in advance for your help!
