Control of image quality of an earth observation satellite must be permanently carried out during all orbit life. To achieve this, reference images of three types of targets were taken into consideration ,by Alsat-1 (First Algerian launched Satellite) between early 2004 and late 2006: • The first target is an homogeneous white region (clear snow) of the Antarctica and above the Arctic regions. • The second target is a dark region taken by night over the Pacific Ocean in order to emphasize variations of dark noise, • The third target is a clear area along the Rail Road Valley (Nevada, United States) in which radiation is measured on the ground and simultaneously to get the absolute calibration of on board instruments.
