A new fast attitude determination algorithm based on panoramic annular lens has been developed. The panoramic annular lens is used as the static infrared sensor, which forms a large field of view to get the infrared image of the Earth. The algorithm of PAL projects the image points onto the virtual earth formatting a space circular loop. The points on this loop are used to construct the spatial vectors. Through the cross product of these spatial vectors, the micro-satellite direction vector can be estimated. This algorithm abandons the iterative process, which reduces the calculation time to meet the demand of rapid maneuver of micro-satellite.
