The SAS-A aspect systemOn Dec. 12, 1970, the United States Small Astronomy Satellite-A was launched into orbit around the earth. The X-ray instrument carried by the spacecraft was the first satellite instrument to be devoted exclusively to the study of stellar X-ray sources. The primary objective of the instrument was to perform an all-sky survey to detect and locate stellar X-ray sources with location accuracies of one arc-minute for the stronger sources. A system description is given together with details of circuits, alignment procedures, and calibration sequences.
