Multiple aperture optical telescopes: some key issues for earth observation from a GEO orbit

Abstract

ONERA is currently conducting a study on the feasibility of an imaging interferometer for Earth observation from a GEO orbit. During this study, some key elements for the definition of such an instrument have been identified and studied. The results obtained so far confirm the applicability of wide-field optical interferometry with a Michelson-type instrument for Earth observation from a GEO orbit.
