The advent of commercial observation satellites with an increasingly fine resolution requires the definition of whenever more accurate geometrical models to correct most of the main image distortions. This effort must be taken into account earlier in the image processing chain so as to minimize the use of external references, sometimes unavailable and often(More)
1. ABSTRACT Since SPOT1, the French national space center (CNES) has worked on improving the geometry of Earth observation spacecrafts. The accuracy of sensor calibration is one of the main key points for any Earth observation application such as orthorectification, DEM generation or surface change detection [6]. Two families of methods have been developed(More)
PLEIADES is the highest resolution civilian earth observing system ever developed in Europe. This imagery program is conducted by the French National Space Agency, CNES. It operates since 2012 a first satellite PLEIADES-HR launched on 2011 December 17th, a second one should be launched by the end of the year. Each satellite is designed to provide optical 70(More)
