This Natural Satellite DataBase (NSDB), sponsored by the FP7 program European Satellite Partnership for Computing Ephemerides (ESPaCE) of the European Union proposes an access to the astrometric observations of the Natural Planetary Satellites (except the Moon) for dynamical studies and ephemerides making.
This database gathers first the data reduced in the framework of the ESPaCE program. It will include also all the astrometric data included at the present time in the NSDB1 repository. All these data were under the scientific authority of the Working Group on Satellites of the International Astronomical Union from 1991 to 2014.
Other data on Satellites such as topographic data and physical parameters are also available. Ephemerides issued from these data are proposed.
