A design of a rotating modulation collimator system which is appropriate to monitoring the occurrence of X-ray bursts in a wide field of the sky is described. Whenever the burst occurs in the field of view, its celestial position is determined to an accuracy of 〜0.5° with the coarse collimator system, and when a certain burst source is continually active, the fine colimator system may be pointed to its approximate direction and the source position is determined to an accuracy of 〜2 arcminutes which may be adequate to lead to the optical and/or radio identification. This system, which combines the precise determination of the source position with a wide field of view, is suited to a small satellite. A specific design is proposed for a small Japanese satellite CORSA-b which is due early in 1979.
