A simulation of the pointing performance of the Solar Optical TelescopeThe Space Shuttle-based Solar Optical Telescope (SOT) will be able to resolve details subtending 0.1 arcsec for continuous viewing over several hours. The SOT's jitter must contribute only 0.03 arcsec rms pointing error over the observation periods; this requirement is addressed with several control system layers encompassing the Shuttle, the Instrument Pointing System, the Prime Focus Image Control Functional System, and the Gregorian Focus Image Control Functional System. The mathematical models for system pointing stability presented give attention to the interaction of the structural and control systems on pointing stability and to Space Shuttle disturbances.
