Abstract

A development program was conducted to further improve the technology readiness level of the Generic Flight Interferometer (GFI), a candidate technology for the future hyperspectral sounder on MTG. Interferometer-based sounders have already demonstrated their performance and reliability in conducting advanced sounding tasks in recent missions (METOP-A, IBUKI, SCISAT). The transition from previous single-pixel (or few) to large-format array detectors offering strong hyperspectral capabilities adds technical challenges to the interferometer design. Some of the improvements required to address those challenges have already been implemented in recent deployment of hyperspectral commercial products but must be adapted to the space environment and constraints. Other improvements are dictated by mission specifics but still tend to be recurrent in recent opportunities. The GFI design intent is to regroup these innovations in a generic modular interferometer platform in order to address a variety of missions with minor modifications and hence lower development costs and risks.
