Looks like there are some pre-packaged set ups out there: https://matesy.de/en/products/magnet-measurement-calibration/helmholtz-coil Since the goal is to do this indoors, could I simply perform the tumble test using the Helmholtz coil with my current method of calibration, with respect to the...

Pretty loose accuracy of +/- 15° for the end application of the compass...

Currently using a similar method to compensate for the hard-iron and soft-iron biases from my onboard electronics: https://github.com/kriswiner/MPU6050/wiki/Simple-and-Effective-Magnetometer-Calibration This method though, also looks at the field around the device as well as the magnetic field...

Thanks for the replies, I guess the key is creating enough of a magnetic field so much so that I can rely on it drowning out the other sources of magnetic interference in the room. Believe it or not competitors don't post too much about their calibration techniques, I did find some whitepapers...

How would one go about calibrating several magnetometers in a production environment? The magnetometer is being used for the purposes of a compass. Currently I'm calibrating them one-by-one in an open field free from magnetic interference (i.e. no hard or soft iron around) by rotating my...

This helps, thank you.

Right, this isn't a pacemaker or anything like that. I'm just looking for something basic to get started. Did you post a link?

Hello, I am an engineer at a small medical device company and have hired an engineering firm to develop a medical device for our company. The first document I have been charged with providing them is a "Request for Proposal" or a "Request for Quotation". Since I am an engineer, I know that...
