We are now pretty confident that the raspi and battery pack have a significant effect on the magnetic field experienced by the IMU (Xsens). We have mostly been able to work around this by recalibrating it, but that's inconvenient and doesn't always work.

We should place the IMU elsewhere in the boat where it's less affected by electric currents, but ensure that it's still protected from water as well. One option might be to get a holder for the bare Xsens board, rather than using the USB developer board.
