Magneto-Inductive Technology Overview; Andrew Leuzinger & Andrew Taylor, February, 2010
Overview of how PNI's magneto-inductive (MI) sensor technology works, with a discussion of some key advantages that set MI apart from other magnetic sensing technologies.
Tilt-Induced Heading Error in a 2-Axis Compass; Andrew Leuzinger, July 2010
Discusses how a 2-axis compass works, with further explanation of earth's magnetic field inclination (dip angle) and the effect of this inclination on 2-axis compass heading.
Local Magnetic Distortion Effects on 3-Axis Compassing; Michael Garton, Anthony Wutka & Andrew Leuzinger, July 2009
Reviews sources of localized magnetic distortion and how to correct for these distortions to obtain accurate compass readings. The paper also provides a review of the tests performed at PNI to measure the effectiveness of magnetic distortion correction algorithms on 3-axis compasses from 3 different companies.
