ELECTRONIC BORESIGHT Pairs of level sensing devices are used in a method that aligns plane surfaces to one another. One of the pairs of level sensing devices is located on each of the plane surfaces. the level sensing devices of each pair are aligned and positioned parallel to two orthogonal axes of the plane. The output signals from corresponding ones of the pairs are differentially compared, and one of the platforms adjusted in pitch and roll to minimize the values produced by the differential comparison. The platforms are then tilted equal amounts and adjusted in azimuth.
