Abstract
Advanced boresight equipment and methods of using the same to effect a transfer of a two- or three-dimensional frame of reference from an ADL to a device to be boresighted. The equipment includes a stationary inertial sensor that is boresighted with respect to a reference line (such as the aircraft ADL). The stationary inertial sensor includes a first gyroscopic combination for generating a first output indicating a two- or three-dimensional frame of reference based on the ADL, and a docking station. The docking station facilitates alignment of a portable inertial sensor that also has a gyroscopic combination for generating a second output indicating its frame of reference. The portable inertial sensor may be identical to the first inertial sensor, or it may additionally include means for automatic optical operation including a gimbal and a gimbal drive system, an electromagnetic energy beam generator for projecting a beam, a second gyroscopic combination for generating a second output signal indicating a frame of reference, and a collimator for indicating an angle between two beams. The various methods of using both embodiments are also described. The invention provides unique cal…
