The compass in the Moitessier HAT, as any compass, needs to be calibrated or you will get wrong data. You should be able to calibrate even when it is placed close to metallic objects but if you put the HAT close to speakers or any big magnetic interference you will not be able to calibrate any compass.
We recommend this active antenna to be connected to the Moitessier HAT, it works like a charm: https://shop.sailoog.com/accessories/6-g...ector.html for cases when the built-in antenna is not enough. but most cases do not need an external antenna.
"The compass I. Opencpn gets its data from the Hat's compass, OT from the GPS heading, doesn't it? "
Sorry I do not understand this question, could you be more specific?
