Pre-flight and in-flight geometric calibration of SPOT5 HRG and HRS images

Abstract

This paper deals with geometric calibration of SPOT5 location model. Focus is set on commissioning phase results for which calibration has been performed in-flight as well as on ground. That is, relative reference frames orientation, CCD line distortion of HRG and HRS cameras, THR processing and tuning of steering mirror damping duration. To start with, I give a brief on main improvements of SPOT5 location model.
