Abstract

This paper presents the first ever `scorecard' showing how well the Space Interferometer Mission is expected to meet the vibration attenuation requirements for its instrument. The spacecraft reaction wheel assembly, the primary on-board vibration source, shakes the structure in the frequency range from 2 Hz to 1000 Hz. Optical path differences and wavefront tip-tilts must be maintained to a few nanometers and tens of milli-arcseconds respectively, in this disturbance environment.
