ABSTRACT:
A calibration device for establishing a 3-D reference frame for an inertial sensor system. A secondary mounting surface on the calibration device is used to provide a measurement of the reference line required for inertial system installation alignment. This device provides a means for establishing a highly accurate alignment of inertial system sensors relative to the output coordinates, called the "mounting frame", without a requirement for optics or a manual transfer of data. By rotating the inertial sensor system through use of a rate table into planes which are substantially perpendicular to each other, the mounting frame for the sensor system can be established.
