Abstract
This paper describes a simple pushbroom camera model for Earth 
observation satellites and proposes a new algorithm to refine the 
orientation parameters of a camera from a set of ground control points. 
The relative importance of the various orientation parameters are 
analyzed. On the last generation of very high resolution satellites such 
as Pléiades and WorldView, the attitude angles are shown to be the main 
contributors to localization errors. Thus the proposed algorithm focuses 
on refining the attitude angles. It is based on a simple polynomial 
fitting method. Numerous experiments, which can be reproduced through 
the online demo associated to this paper, show that the proposed 
algorithm is able to reduce the localization error by one order of 
magnitude with only a few ground control points. A geometric simulator 
for the proposed model is implemented, as well as the attitude 
refinement algorithm.
