Venµs geometric image quality commissioning

Image calibration and performance assessment activities of the commissioning phase of Venµs EO mission took place in the second semester of 2017 and the first semester of 2018. As for the geometric image quality part, this phase consisted in assessing and correcting the pointing bias, assessing the geolocation performance, calibrating the line of sight (LOS) of each detector, assessing the multi-spectral as well as multi-temporal registration performances, and assessing and setting up reference images. Since the geometric commissioning has been disturbed by attitude restitution errors, this paper gives a feedback on how we adapted the geometric calibration as well as the production processing in order to fulfill the requirements with a minimum of cost. These changes have a non-negligible impact on ~20% of the products. The image registration methodology is presented and discussed. Current registration performances are finally presented.
