ABSTRACT.
THE GROWING NEED FOR A BETTER QUALITY IN SATELLITE IMAGES, IN TERMS OF IMAGE RESOLUTION, IS ALSO TRANSLATED AS REQUIREMENTS OF A STILL BETTER ACCURACY IN THE SATELLITE CONTROL AND ATTITUDE DETERMINATION. DUE TO THIS, THE SEARCH FOR SOLUTIONS THAT COULD SUPPLY THESE NEEDS IS STILL FAR FROM ITS END. THIS WORK MAIN CONCERN IS THE SPOT SATELLITE IMAGING INSTRUMENT MODELLING AND THE ESTABLISHMENT OF A VECTORIAL FIELD RELATING EACH IMAGED POINT TO THE SATELLITE MASS CENTER. FROM THE STUDY OF SUCH A FIELD ONE COULD EXTRACT IMPORTANT INFORMATION ON THE SATELLITE ATTITUDE. ALSO IN THIS WORK WE COMMENT SOME POSSIBLE ACTIONS THAT COULD LEAD TO AN EFFECTIVE INTERACTION BETWEEN IMAGING AND THE ATTITUDE DETERMINATION AND CONTROL SYSTEM OF THE REMOTE SENSING SATELLITE.
KEYWORDS. SATELLITE, ATTITUDE, DETERMINATION, IMAGING, SPOT.
