Abstract:
1. A positioning system used in the calibration of a single or multi axis sensitive instrument, comprising: a rigid cuboidal frame defining six planes and a mounting region within said six planes adapted to have an axis sensitive instrument coupled thereto such that each axis of sensitivity of said instrument is approximately parallel to four planes of said six planes and perpendicular to two opposing ones of said six planes that are not included in said four planes; a plurality of feet mounted on said frame to define a resting plane associated with each of said six planes, each said resting plane offset from said frame and parallel to one of said six planes; and means for defining first and second flat surfaces that are approximately perpendicular to one another with said first surface adapted to be oriented relative to a local or induced reference field, wherein said frame with said inclinometer coupled thereto is positioned such that said feet associated with one of said resting planes tangentially contact said second flat surface and said feet associated with another of said resting planes tangentially rest on said first flat surface.
