In the second post of this blog, I described a rather complicated method to calibrate the Raymarine ST60+ wind vane transducer. I have now ...

I have completed the assembly of my custom compass. As explained in a previous post , it has a resolution of better than 0...

To calculate a tilt-compensated magnetic heading, we start with x-y-z raw measurements from the accelerometer (ar x , ar y , ar z ) and from...

The magnetometer calibration of the prototype compass uses the same arrangement that was described in the last post for the accelerometer. ...

A first prototype of a custom compass has been built, and an improved calibration procedure for the accelerometer has been tested. The co...

In Part 1 of this post, I have presented the MagCal software that is used to calibrate a 3-axis magnetometer (or accelerometer). One pro...

Note: the MagCal software is no longer available on the University of Calgary site. See Part 2 of this post for the replacement Magneto soft...
