The spin rate was controlled by a gyroscope that could be commanded to stop rotation so that all instruments could be pointed at a given source. Pointing could provide about 30 minutes of continuous data on a source, such as a pulsar, burster, or transient. This is an artist’s conception of the satellite in orbit.. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/sas3/sas3.dc.xml Thu, 01 Jan 1970 12:00:00 GMT
