We have some soft metal (Aluminum) near the IMU but no hard metal. In the previuous plot we are moving the boat in order to lose the calibration so the change in the magnetic field is manly due to that. As you could see in the first part of the graph, where we are still, the only change in the magnetic field is some spike noise maybe due to the electronic noise. Attached is the updated graph with also the gyro data. (for reference the x axis now is in seconds)   Gyro                                                                                                                    Mag      ... View more

So should we turn slower? We noticed that the magnetometer loses its calibration also when the boat slowly drifts because of the waves. Is there anything we can do in order to keep the magnetometer reliably calibrated? Thank you for your support ... View more

We are currently doing the test by manually moving the boat. The calibration status of the magnetometer drops only if we move it. If we keep it in one position without moving, the calibration doesn't change. This is the plot of the magnetometer from status 3 of calibration to 1. The violet line is the calibration status (from 30 = 3 to 10=1). The time on X axis is in milliseconds   ... View more
