Abstract: The Three-Axis Cube Positioner was developed to generate Angle Standards of Reference in Three Mutually Orthogonal Directions on one robust kinematic platform. This Standard provides an efficient and microradian accurate means to correlate, boresight and calibrate one or more test targets, target simulators, and/or optical transfer standard measurement instruments to a products three coordinate spatial datum. Advanced Military Tactical and Strategic Electro-Optical Sensor and Targeting Systems can sense a given target with increased range and require more stringent boresight tolerances. The systems may incorporate more than one sensor subsystem and the multiple sensors may point in different directions. These multiple sensors must be correlated to a common datum set, namely the spacecraft or aircraft coordinate system. In addition, several target simulators may be required for ground based testing, simultaneously, to verify acceptable performance from many different directions with multiple targets at various simulated distances (Fields of View, FOV). The processes are inside-out, and developed using the Three-Axis Cube Positioner standard.
