Спутник ДЗЗ. Sentinel 3A. [Редактировать]

Основной целью миссии Sentinel-3 является наблюдение за топографией поверхности океана, температурой поверхности моря и суши, цветом океана и суши с высокой степенью точности и надежности для поддержки систем прогнозирования состояния океана, а также для мониторинга окружающей среды и климата. Sentinel-3 — наследник хорошо себя зарекомендовавших спутников ERS-2 и Envisat. Его инновационное оборудование включает в себя:

  • SLSTR (Sea and Land Surface Temperature Radiometer) — аналог радиометра AATSR (Advanced Along Track Scanning Radiometer), которым оснащен спутник Envisat. Он измеряет температуры с точностью не хуже 0,3 К и имеет улучшенные характеристики по сравнению с AATSR, в том числе и по учету атмосферной коррекции. SLSTR будет проводить измерения в 9 спектральных каналах и 2 дополнительных каналах, оптимизированных для мониторинга пожаров. Пространственное разрешение в видимой и инфракрасной коротковолновой зоне спектра – 500 м, а в тепловых инфракрасных каналах — 1 км.
  • OLCI (Ocean and Land Colour Instrument) — аналог спектрометра MERIS (Medium Resolution Imaging Spectrometer), которым оснащен спутник Envisat. Число спектральных каналов в OLCI увеличено с 15 до 21, конструкция прибора оптимизирована для минимизации влияния солнечных лучей, пространственное разрешение — 300 м. OLCI — новое поколение инструментов для измерения параметров океанов и суши. Полосы охвата OCLI и SLSTR (в надире) полностью перекрываются.
  • Двухчастотный (Ku- и С-диапазон) радар SRAL (Synthetic Aperture Radar Altimeter) базируется на разработках для спутниковой системы CryoSat и обеспечит измерения с разрешением ~ 300 м в режиме SAR вдоль маршрута. Он будет поставлять точные данные о топографии поверхности океана, которые имеют существенное значение для океанографических задач и мониторинга климата. SRAL также будет осуществлять точные измерения топографии морского льда, ледовых щитов и т. д.

Пара спутников Sentinel-3 будет иметь высокую повторяемость съемок: менее двух дней для OLCI и менее одного дня для SLSTR на экваторе. Орбиты спутников (815 км) обеспечат получение полного пакета топографических данных каждые 27 дней. Запуск первого спутника миссии Sentinel-3 запланирован на 2013 г., сразу же после Sentinel-2, что обеспечит выполнение предусмотренных программой GMES соответствующих сервисов. Спутник Sentinel-3B планируется запустить в 2018 г. Данные, получаемые практически в реальном режиме времени, будут использоваться для прогнозирования океанических процессов, картографирования морских льдов. Спутники обеспечат информацией службы, наблюдающие за экологическим состоянием морей и нуждающиеся в точных и оперативных данных о состоянии поверхности океанов, в том числе о температуре воды, океанических экосистемах, качестве воды и мониторинге загрязнения окружающей среды. Сервисы GMES, связанные с наблюдением за земной поверхностью, также будут получать полезную информацию со спутников Sentinel-3, связанную с мониторингом изменений земной поверхности, лесного покрова, качества почвы, выявлением природных пожаров.

Le satellite Sentinel-3A construit par Thales Alenia Space a été lancé avec succès Cannes, 16 février 2016 – Le satellite Sentinel-3A, réalisé par Thales Alenia Space pour le compte de l’Agence Spatiale Européenne (ESA) a été lancé avec succès depuis la base de Plesetsk, à bord d’un lanceur Rockot. Pierre angulaire du programme européen Copernicus, Sentinel-3A se distingue par l’emport d’une série d’instruments à la pointe de la technologie. Grâce aux 4 instruments à son bord - un altimètre associé à un radiomètre micro-onde pour la topographie de surface, et deux instruments mesurant indépendamment les couleurs et températures des océans et zones de surface, incluant les lacs et les rivières, Sentinel-3A accomplira de nombreuses missions pour l’océanographie, l’environnement et l‘étude du changement climatique. Le satellite Sentinel-3A fournira une couverture systématique de toutes les zones de surface et des océans. Les données récoltées contribueront notamment à l’amélioration des prévisions océanographiques et atmosphériques. Elles permettront aussi d’avoir une meilleure connaissance de l’état de santé de l’océan, de mieux gérer les ressources halieutiques, agricoles, forestières, la biodiversité, les ressources en eau, la santé publique, la production, la sécurité alimentaire, et de surveiller avec précision les changements de niveau de la mer ainsi que la diminution de la banquise arctique. Le lancement de Sentinel-3A fait suite à celui de Sentinel-1A, également fabriqué par Thales Alenia Space et lancé le 3 avril 2014. La continuité des données sera assurée par les séries Sentinel-1 B/C/D et Sentinel-3 B/C/D, tous sous maîtrise d’œuvre Thales Alenia Space. Sentinel-3B est prévu au lancement en 2017 à bord du lanceur Vega d’Arianespace. Les satellites Sentinel-3C et 3D, qui seront lancés à partir de 2021, ont récemment fait l’objet d’un contrat de 450 M€ entre Thales Alenia Space et l’ESA. « Après MSG-4 et Jason 3, Sentinel-3A est le 3ème satellite construit par Thales Alenia Space, dédié au climat et à l’environnement et lancé en un peu plus de 6 mois », a déclaré Jean Loïc Galle, Président Directeur Général de Thales Alenia Space. « Nous sommes fiers du succès du lancement d’aujourd’hui car il confirme à nouveau l’expertise incontournable de notre société dans la réalisation de satellites d’observation de la terre. Thales Alenia Space a une fois de plus mis ses compétences à contribution pour relever un challenge technologique majeur dans le cadre du programme Copernicus, qui met en évidence le rôle déterminant de notre société parfaitement en adéquation avec la vision stratégique de l’Europe. » A propos de Thales Alenia Space Acteur spatial incontournable en Europe dans les domaines des télécommunications, de la navigation, de l’observation de la terre, de l’exploration et de la réalisation d’infrastructures orbitales, Thales Alenia Space est une Joint-Venture entre les groupes Thales (67%) et Finmeccanica (33%). Aux côtés de Telespazio, Thales Alenia Space forme la Space Alliance et propose une offre complète de solutions incluant les services. Grâce à son expertise unique en matière de missions duales, de constellations, de charges utiles flexibles, d'altimétrie, de météorologie ou d'observation optique et radar haute résolution, Thales Alenia Space se positionne comme le partenaire industriel naturel pour accompagner les grands pays dans le développement de leur plan spatial. Thales Alenia Space a réalisé un chiffre d'affaires de plus de 2 milliards d’euros en 2014 et emploie 7500 personnes dans 8 pays. www.thalesaleniaspace.com Contacts presse Thales Alenia Space : Sandrine Bielecki Tel: +33 (0)4 92 92 70 94 Chrystelle Dugimont Tel: +33 (0)4 92 92 74 06 sandrine.bielecki@thalesaleniaspace.com chrystelle.dugimont@thalesaleniaspace.com
