Abstract
An active boresight drift measurement and calibration apparatus utilizing a predetermined number of interferometer units to measure the distances between themselves, the target tracking unit and the beam direction sensing unit. The interferometer units provide the initial alignment reference and by periodic repeat measurements provides distance change data to establish boresight alignment drift correction angles.
