Hello there!
I am planning to deploy Hydromoths over an area of around 400x400 meters, and I want to be able to localize boats passing by. Has anyone tried something similar? I read about the GPS board that can be used to reduce the time drift and improve accuracy. Has anyone tried this with the Hydromoths? is it even possible?
Hi, The HydroMoth clock won't be accurate enough for localisation without external synchronisation. The best way to achieve this would be with a standard AudioMoth with a GPS Hat, or AudioMoth Dev and the GPS board, plus an external hydrophone. We use Aquarian H2D hydrophones that plug directly into the AudioMoth 3.5mm jack. Alex
