Abstract

PURPOSE:To obtain high-accuracy attitude information by determining a specific quadrant that the phase difference of incident beacon light belongs to a cos type and sin type interference pattern mask and the output of an interference pattern processing part. CONSTITUTION:Light collectors 10 and 11 receive the beacon light from a ground station and their light beams are guided to two nearby points through optical cables 12 and 13 to form interference fringes. Then they are projected on the cos type and sin type interference pattern mask 15 of the interference pattern mask 15 and the total quantity of light transmitted through it is measured. An attitude angle measurement part 22 processes a cos type and a sin type output and a mean intensity output which are found to find the variation number of the quadrant that the phase difference of the coherent light belongs to, and the variation of the quadrant is integrated to detect an attitude angle.
