| Abstract: | We utilize data from the ultra-violet imaging telescope (UVIT) data to make an assessment of the high-frequency pointing stability, called the jitter (>2 Hz), of the AstroSat bus. We find a pointing stability of 0.06 arcsec standard deviation with no significant frequency response between 1 and 14 Hz, aside from a temporary effect at 2.4 and 5.2 Hz upon the telescope pointing induced from movements of the SSM camera.
