In the optical-mechanical scanner which uses an oscillating mirror to scan cross tracks, the correction of spacecraft motion can decrease the scan frequency and increase the scan efficiency by a factor of 2, respectively. This is very valuable. The MODIS-N correcting concept and its application axe discussed in this paper.
