The astrometric monitoring of the natural planetary satellites is an important step to assess the formation and the evolution of these systems. However, in order to quantify relevant gravitational effects such as tidal forces, it is necessary to have

Accurate positional measurements of planets and satellites are used to improve our knowledge of their dynamics and to infer the accuracy of planet and satellite ephemerides. In the framework of the FP7 ESPaCE project, we provide the positions of Mars

During the 1985–1986 appearance of Comet Halley, hundreds of photographic images were taken by the authors. These images were obtained with several telescopes, using different photographic emulsions and filters. All photographic images have subsequ
