Il est d\u00e9velopp\u00e9 dans le cadre d&rsquo;une collaboration entre le CNSA (China National Space Administration) et le CNES (Centre National d&rsquo;Etudes Spatiales) et doit \u00eatre lanc\u00e9 en 2021. Son objectif est de d\u00e9tecter les sursauts gamma (GRB = Gamma Ray Burst) en temps r\u00e9el et de capter un maximum d&rsquo;informations correspondantes. Il est compos\u00e9 d&rsquo;un segment spatial (un satellite embarquant une vari\u00e9t\u00e9 de capteurs), associ\u00e9 \u00e0 un r\u00e9seau international d\u2019antennes au sol, le tout g\u00e9r\u00e9 par les deux agences.<\/p>\n<p>La conception de ce syst\u00e8me a \u00e9t\u00e9 r\u00e9alis\u00e9 \u00e0 l\u2019aide du processus historique du CNES, bas\u00e9 sur un ensemble de documents textuels, d\u00e9riv\u00e9s et raffin\u00e9s, depuis les exigences haut niveaux jusqu\u2019\u00e0 la sp\u00e9cification technique des \u00e9quipements. Dans ce contexte, la validation des sp\u00e9cifications obtenues repose majoritairement sur de l\u2019expertise humaine et sur les campagnes de validation qui sont men\u00e9es. La complexit\u00e9 d\u2019un tel syst\u00e8me en fait un parfait candidat \u00e0 l\u2019exp\u00e9rimentation du processus MBSE (ing\u00e9nierie des syst\u00e8mes bas\u00e9e sur les mod\u00e8les) \u00e0 l\u2019aide de Capella. Deux projets successifs ont \u00e9t\u00e9 r\u00e9alis\u00e9s dans ce contexte : une premi\u00e8re \u00e9tude a permis de confronter le processus actuel aux principes du MBSE pour en \u00e9valuer les b\u00e9n\u00e9fices (sur un \u00e9chantillon du syst\u00e8me mais \u00e0 travers les diff\u00e9rentes couches d\u2019ing\u00e9nierie). Compte tenu des r\u00e9sultats prometteurs, un deuxi\u00e8me projet, bas\u00e9 sur les mod\u00e8les Capella r\u00e9alis\u00e9s durant le premier projet, s\u2019est int\u00e9ress\u00e9 \u00e0 la capture op\u00e9rationnelle des donn\u00e9es de validation du syst\u00e8me (p\u00e9rim\u00e8tre de validation, s\u00e9quences de tests\u2026).<\/p>\n<p>Cette incursion de Capella dans le processus d\u2019ing\u00e9nierie du CNES a \u00e9t\u00e9 particuli\u00e8rement bien re\u00e7ue. Les experts SVOM ont \u00e9t\u00e9 conquis par cette nouvelle fa\u00e7on de travailler. La mise en place d\u2019une chaine outill\u00e9e op\u00e9rationnelle bas\u00e9e sur les mod\u00e8les pour la capture de l\u2019architecture syst\u00e8me et de la sp\u00e9cification de validation associ\u00e9e ouvre la porte \u00e0 une plus large diffusion du MBSE au sein du CNES.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>[siteorigin_widget class=\u00a0\u00bbSiteOrigin_Widget_Image_Widget\u00a0\u00bb][\/siteorigin_widget] Artal technologies participe aux Capella Days 2020 qui se d\u00e9rouleront en ligne Le 12 octobre \u00e0 17h25 | inscription Retrouvez [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"link","meta":{"ngg_post_thumbnail":0,"footnotes":""},"categories":[121],"tags":[],"class_list":["post-1188","post","type-post","status-publish","format-link","hentry","category-news","post_format-post-format-link"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.7 -
