Contributions possibles de l'astrométrie spatiale à la définition d'un système de référence absolu.
Abstract
An extension of absolute celestial reference systems was studied that includes diversity of the characteristics of reference objects and their celestial densifications. Two methods are proposed: series interferometer observations at different wavelengths and the use of an intermediate terrestrial system. It is also possible to make the astrometry system absolute by including star heaps in the observational programs. This does not exclude the necessity of making intercomparisons with other systems.
