The article deals with the factors affecting the quality of formation and resolution of an image in a high-resolution scanner (HRS). It is shown that the stabilization parameters of a spacecraft (SC), on which a HRS with a charge-coupled device operating in time delay integration mode (TDI-CCD) is installed, signifi­cantly affect an image distortion, namely its blurring, and this blurring increases when the number of inte­gration lines goes up in the TDI sensor. The analysis and modelling of the maximum permissible number of integration stages in CCD8091 TDI-sensor employed in a HRS are conducted. We analyse the effect of a deviation in the nominal (planned) flight altitude of a SC above the Earth's surface on limiting the highest possible number of integration stages. The results obtained make it possible to assess the impacts on the image quality and resolution, and choose a compromise variant for the best results.
