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.

Press Release SPACE SYSTEMS 16. Februar 2015 Satellit Sentinel-3A zur Ozeanbeobachtung erfolgreich gestartet  Von Airbus Defence and Space gebautes Mikrowellenradiometer an Bord von Sentinel-3A korrigiert durch Wasserdampf in der Atmosphäre verursachte Messfehler  Satellit zur Quasi-Echtzeit Überwachung der Meeres-, Eis- und Landflächen der Erde mit Rockot-Trägerrakete gestartet Das erste der zwei Sentinel-3-Flugmodelle, der Satellit Sentinel-3A, ist an Bord einer RockotTrägerrakete vom russischen Kosmodrom Plessezk erfolgreich gestartet. Hauptauftragnehmer für Sentinel-3A ist Thales Alenia Space. Sentinel-3A ist mit einem Mikrowellenradiometer (MWR) von Airbus Defence and Space ausgerüstet, das Signalstörungen eliminiert, die durch Wasserdampf in der Atmosphäre entstehen. Dies ermöglicht eine genaue Erfassung unterschiedlicher Wasserflächen: offene See, Küstenbereiche, Meereis und Binnengewässer. Das 26 Kilogramm schwere MWR misst die von der Erde ausgesendete Wärmestrahlung und damit die durch Feuchtigkeit in der Troposphäre bedingten Impulsverzögerungen, die für die genaue Erfassung von Radarhöhenmessdaten zu berücksichtigen sind. Airbus Defence and Space war zudem verantwortlich für die thermische Auslegung des Service- und Nutzlastschnittstellenmoduls. Dieses gewährleistet das korrekte Funktionieren der Instrumente unter den extremen Temperaturschwankungen, denen der Satellit in der Umlaufbahn ausgesetzt ist. Das Unternehmen lieferte darüber hinaus ein Kryokühlersystem für das Instrument SLSTR (Sea and Land Surface Temperature Radiometer). Die Sentinel-3-Mission ist speziell auf die langfristige Erfassung und Bereitstellung qualitativ hochwertiger Messdaten für Meeres-, Land- und Atmosphärenbeobachtungsdienste ausgelegt. Die Sentinels stützen sich auf die von Airbus gebauten Vorgängermissionen ERS, Envisat und SPOT und die von ihnen erfassten Daten. Zudem warten sie mit Verbesserungen bezüglich der betriebserforderlichen Wiederholraten auf und erleichtern die Entwicklung neuer Produkte und Dienste. Die Sentinel-3-Mission ermöglicht die Ausweitung der Beobachtung auf Binnen- und Küstengewässer. Hauptziel der Mission ist die Überwachung der Ozeane, einschließlich der Messung Temperatur, Farbe und Höhe der Meeresoberflächen sowie der Dicke des Meereises. Messdaten ermöglichen Wissenschaftlern die Überwachung von Veränderungen Meeresspiegels und der Meeresoberflächentemperatur ebenso wie die Beobachtung Wasserqualität, Meeresverschmutzung und biologischer Produktivität. von Die des von Press Release Ergänzend zu den Daten der multispektralen optischen Erderkundungsmission Sentinel-2 bietet Sentinel-3 einen Dienst zur Überwachung der Landoberflächen mit Waldbranddetektion sowie zur Kartierung von Landnutzung und Vegetationszustand. Sentinel-3A hat die Größe eines Kleinwagens, eine Masse von 1.150 Kilogramm und eine geplante Nutzungsdauer von sieben Jahren. Eurockot Launch Services GmbH mit Sitz in Bremen ist ein Gemeinschaftsunternehmen von Airbus Safran Launchers und dem Space Center Khrunichev. Neben dem Sentinel-3A-Start wird Eurockot noch zwei weitere Satellitenstarts im Rahmen des europäischen CopernicusProgramms durchführen. Airbus Defence and Space Airbus Defence and Space ist eine Division des Airbus-Konzerns, die aus der Zusammenlegung der Geschäftsaktivitäten von Cassidian, Astrium und Airbus Military entstanden ist. Die neue Division ist das führende Verteidigungs- und Raumfahrtunternehmen Europas, das zweitgrößte Raumfahrtunternehmen der Welt und unter den zehn größten Verteidigungsunternehmen weltweit. Sie erzielt mit mehr als 38.000 Mitarbeitern einen Jahresumsatz von rund 13 Mrd. €.
