Enhance button is a very common movies trope, where a character scrolls through some video footage or photos and asks a computer to enhance its resolution to an insane level of details, enabling solving crime mysteries and conspiracies of all sort with clues that were invisible in the original image. While this meme has been […]
In a previous post, we showed that spatio-temporal fusion methods would enable to obtain hybrid data with the revisit of the S2-NG mission (3 to 5 days), and the resolution of the Sentinel-HR mission (2 m), with an uncertainty better than the atmospheric correction errors (better than 0.01 in reflectance). In this section, we tested […]
Three years ago, we started the phase-0 study of a mission named Sentinel-HR : S-HR would be a satellite mission to complement Sentinel-2 new generation (S2-NG) with In that study, one of our assumptions was that a lower revisit frequency than that of Sentinel-2 was sufficient. This seems possible because, in most cases, the high frequency […]
=> As agreed by CNES, the Sentinel-HR phase-0 study report has been published on HAL. This report can therefore be widely shared and cited in your own work: Julien Michel, Olivier Hagolle, Anne Puissant, Pierre-Alexis Herrault, Thomas Corpetti, et al.. Sentinel-HR Phase 0 Report. [Research Report] CNES – Centre national d’études spatiales; CESBIO. 2022. ⟨hal-03643411⟩ […]

=> In our a priori definition of Sentinel-HR mission, we had included an option to observe the 3D topography at a high resolution, with a moderate accuracy ambition (lower than that offered by the CO3D satellite, as shown in the table below), but globally and with a systematic revisit. But our mission advisory group insisted, […]
=> Dans notre définition initiale de la mission Sentinel-HR, nous avions inclus une option permettant d’observer le relief à haute résolution, avec un objectif de précision modéré (inférieur à celui offert par CO3D, comme le montre le tableau ci-dessous), mais avec une revisite systématique et sur le monde entier. Devant l’intérêt des membres de notre […]
