Description
The consortium ESPaCE (European Satellite Partnership for Computing Ephemerides) is composed of seven European institutes: IMCCE (Institut de Mécanique Céleste et de Calcul des Ephémérides, Paris Obs.), ROB (Royal Observatory of Belgium), TUB (Technical University of Berlin), ERIC (European Research Infrastructure Consortium formerly known as JIVE : Joint Institute for VLBI in Europe), TUD (Delft University of Technology), French space agency (CNES) in France and German Aerospace Center (DLR) in Germany. The objective of the consortium, initiated under an FP7-European project is to provide new accurate ephemerides of natural satellites and spacecraft. For this goal astrometric data issued from ground-based observations as well as from space observations are being analyzed and reduced. On the other hand emerging technologies, specifically VLBI and interplanetary laser ranging, applied to the positioning of spacecraft are also studied. The ESPaCE project addresses also data related to gravity and shape modeling, control point network and rotational parameters of natural satellites. The accuracy improvement of these ephemerides makes them a powerful tool for the analysis of space missions, the preparation of future missions, or for the determination of planetary physical parameters. Among relevant sub-products for space missions, we note the delivery of updated ephemerides of the Mars moons Phobos and Deimos derived from data by the Mars Express mission. In addition, the ESPaCE ephemerides of the Galilean moons are regularly updated in the context of the upcoming JUICE mission.
