Abstract
A method for calibrating a sensor includes providing a fixture that defines a first coordinate system, providing a chassis, and orienting a plurality of sensor elements to form a misaligned coordinate system, wherein the misaligned coordinate system axes are oriented at other than right angles with respect to each other. The method also includes coupling the sensor to be calibrated to the fixture and mathematically compensating the misaligned coordinate system to correspond with the first coordinate system.
