Abstract
A method and apparatus for reducing centroiding error of a star sensor having a plurality of pixels is disclosed. The method comprises the steps of computing a star sensor angular slew rate of ω pixels per star sensor integration period τ, collecting star sensor data while slewing the star sensor according to the selected star sensor angular slew rate ω, and filtering the collected star sensor data according to a frequency determined by the selected star sensor angular slew rate.
