Calibration of an Orthogonal Cluster of Magnetic Sensors

Abstract

This report interprets least-squares estimation as a magnetic sensor calibration procedure. The procedure demonstrated can be applied to any inner product type of sensor element to calibrate a single sensor or multisensor unit. The accuracy of the estimates can be quantified. In addition to scale factor and bias, the within-unit alignment and the alignment to a given coordinate system can be estimated.
