摘要：In-flight Image Quality calibration and performance assessment activities depend on specific acquisitions and, for some of them, on dedicated guidance of the satellite platform. The operational constraints may be tedious during the commissioning phase. Moreover, the length of the requested data collection may be conditioned by uncontrolled parameters such as climatic hazard. The new French high resolution earth observing satellite Pleiades-HR will be launched at the beginning of 2010. A specific design and new technologies have been embarked to provide great agility. These capabilities offer new methods to perform the image quality activities. Two are described in this paper. The first one concerns the so-called AMETHIST method to compute the normalization coefficients of the radiometric model. The second one uses the stars to measure the line-of-sight dynamic stability
