I have an AUV with a 12 inch diameter, 29 inch long capsule. Inside the capsule sits an Intel NUC computer, an NVIDIA Jetson GPU, an Arduino Mega, a Sparton IMU (9 DOF) as well as a custom voltage regulator. Given the noise, would it be practical to attempt to use my magnetometer, even with calibration and filtering? If so, what should I keep in mind regarding the placement of my IMU in the AUV's capsule, given that I have already read this post?
I have tried moving it as far away from the sources of noise as possible but the noise persists. I looked into shielding, but that looks like it would block the Earth's magnetic data as well, which would render the shield pointless.
