1. An inertial sensor system calibration apparatus for an inertial sensor system mounted within an enclosure, the enclosure having first and second planar reference surfaces, said calibration apparatus comprising:

  • a rate table; and

    a calibration device comprising;

    a primary mounting member with a primary mounting surface that is substantially planar;

    a secondary mounting member positioned proximate to said primary mounting member, said secondary mounting member has a secondary mounting surface which is substantially planar and substantially perpendicular to the primary mounting surface;

    mounting means which fixes the enclosure on said primary and secondary mounting members so that the enclosure reference surface is flush against the primary mounting surface and a reference edge substantially parallel to the secondary mounting surface is established along the second reference surface; and

    means to position said primary and secondary mounting members on the rate table so that said first and second mounting members rotate about axes normal to the primary mounting surface and said secondary mounting surface.
