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 omega pixels per star sensor integration period tau, collecting star sensor data while slewing the star sensor according to the selected star sensor angular slew rate omega, and filtering the collected star sensor data according to a frequency determined by the selected star sensor angular slew rate.
