Digitizing plates of natural planetary satellites: observations of high accuracy of the past

Many plates were taken from 1967 to 1998 of the systems of natural satellites of Mars, Jupiter and Saturn at the U.S. Naval Observatory in Washington DC. Most of these plates have been reduced at a time where star catalogues were not enough accurate and dense to ensure a good astrometric reduction. The arrival of new accurate catalogues such as the UCAC2 and, in the future, the GAIA catalogue, make valuable the scanning of selected plates from which the positions of the satellites will be used for the improvement of the dynamical models of motions.
