"The operations of Cassini optical remote sensing instruments require a high level of spacecraft-pointing stability to minimize image distortion during an exposure window. This paper summarizes the flight performance of the Cassini spacecraft's pointing stability with respect to mission requirements," scientists writing in the Journal of Spacecraft and Rockets report.
"of spacecraft jitter, the Cassini spacecraft control modes, and pointing-stability metrics are discussed to provide a context for the results. In designing the Cassini attitude-control system, a pointing-stability performance metric that considered the frequency contents of the disturbance sources ...
