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 a diagram of the instruments onboard the SAS-3. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Auger-Animation/sas3_layout/sas3_layout.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/sas3_layout/sas3_layout.dc.xml Designed and built at M.I.T, the SAS-3 was a spinning satellite.
