Спутник ДЗЗ. Sentinel 1B. [Редактировать]

Европейский спутник дистанционного зондирования Земли, который входит в ОГ КА по глобальному мониторингу окружающей среды и безопасности “Copernicus” (предыдущее название GMES) . Разработан “Thales Alenia Space”, которая отвечала за проектирование, разработку и интеграцию аппарата. На борту изделия “Sentinel 1” установлена РЛС с синтезированной апертурой/C-SAR (разработана компанией  “Astrium”), которая обеспечит всепогодную  поставку космических снимков. Съемка будет выполняться в С-диапазоне (длина волны 6 см). После обработки данных в некоторых режимах пространственное разрешение достигнет 1х1 м.
Космический аппарат базируется на платформе Thales Aliena Space PRIMA. Стабилизация аппарата на орбите осуществляется по трем осям с точностью 0.01º. Точность определения положения орбите 10м (по каждому направлению, 3σ). Конструкция аппарата имеет тип параллелепипеда. Центральная часть аппарата выполнена из алюминия с центральной структурой из укрепленной углеволокном пластмассы. При конструировании использовался модульный подход, который позволил производить отдельную интеграцию и тестирование полезной нагрузки, перед интеграцией с платформой аппарата. Конструктивно платформа PRIMA включает три главных модуля, которые функционально разъединены, чтобы допустить параллельную интеграцию модулей.

Модули платформы:

  • SVM (обслуживающий модуль) - несет все обслуживающие системы кроме двигательных установок.
  • PPM (двигательный модуль), несет все системы коррекции орбиты.
  • PLM (модуль полезной нагрузки), несет все оборудование полезного груза включая антенну радиолокационного наблюдения Земли.

Основные системы аппарата:

  • TCS (подсистема терморегулирования). TCS обеспечивает управление за температурными режимами работы аппарата. В целом TCS пассивен, перераспределение тепла осуществляется путем покачивания теплоносителя по трубопроводам через радиаторы и систему многослойной изоляции. Также на борту расположены нагревательные элементы.
  • EPS (подсистема энергопитания). EPS использует две солнечные батареи для производства электроэнергии. Каждая батарея состоит из 5 элементов на основе GaAs элементов. На конец срока активного существования система позволит генерировать 4.8 кВт энергии. Литиево-ионный аккумулятор имеет вместимость 324 ампер часов. PCDU (система распределения энергопитания) разработана, чтобы обеспечивать защиту электрической системы и эффективное распределение электроэнергии. 
  • AVS (авиационная подсистема). AVS выполняет функции обработки и управления положением аппарата на орбите. Конструктивно представляет собой интегрированное решение, которое выполняет контроль за платформой и полезной нагрузкой.
  • PDHT (система обработки и передачи научных данных). Состоит из систем передачи телеметрии, системы антенн и системы хранения информации. Система передачи двуканальная. Работает в X -диапазоне.
  • PRP (двигательная установка). Состоит из  14 ускорителей расположенных на 4-х сторонах аппарата. Одна из групп ускорителей предназначен исключительно для работы в защищенном режиме.
  • RF. Обеспечивает  передачу команд и телеметрии в S-диапазоне. Система поддерживает шифрование команд.
  • Лазерный коммуникационный комплекс. Должен передавать данные на систему ретрансляции ERDS. Работает по направлению НОО-ГСО. Использует LCT (Лазерный Коммуникационный Терминал) производства Tesat-Spacecom (Backnang, Германия). LCT основан на основе разработок подобного устройства для системы (TerraSAR-X). Мощность передатчика 2.2 Вт. Апертура телескопа 135-миллиметров. Планируется, что данное решение будет типовым. Скорость передачи данных системой составит около 2.8 Гбит/с (1.8 Гбит/с скорость передачи полезной информации).

22016-04-25. Запуск космического аппарата Sentinel-1B в очередной раз перенесен.
Arianespace отложила запуск ракеты-носителя "Союз-СТА" с космодрома Куру во Французской Гвиане. Данный перенос пуска уже второй, но, в отличии от первого раза когда помешала погода, в этот раз пуск отменен в связи с техническими причинами.
При этом, Европейское космическое агентство не обнародовало точную причину произошедшего, а ограничилось следующим сообщением "Из-за аномалии, зафиксированной во время обратного отчета при запуске ракеты "Союз-СТА" со спутником Sentinel-1B, обратный отсчет был остановлен. Ракета-носитель и спутник переведены в безопасный режим функционирования. Новая дата запуска будет сообщена после анализа ситуации". Тэги: Союз-СТА с РБ «Фрегат»Sentinel 1B

Traineeship Opportunity for “Young Graduate Trainees” Reference Field of specialisation Duty Station ESA/YG-ESTEC(2015)007 SAR Applied Electromagnetics ESTEC Closing Date 15 December 2015 Overview of the Division’s mission Sentinel-1 is the Synthetic Aperture Radar (SAR) Earth Observation mission of the Copernicus Space Component. It is a polar-orbiting C-band imaging SAR satellite constellation designed to work in a pre-programmed conflict-free operations mode to systematically image global landmasses, coastal zones, sea-ice, polar areas and shipping routes at high resolution, as well as covering the global oceans with vignettes. Sentinel-1 provides an all-weather day-and-night supply of SAR imagery for Copernicus user services. The Sentinel-1 mission is implemented through a constellation of identical C-band SAR satellites comprising the current A and B units. Sentinel-1A was successfully launched on April 3rd, 2014 and the launch of Sentinel-1B is scheduled for the second quarter of 2016. The Copernicus Sentinel-1 Mission will ensure the reliability of operational Earth monitoring services. In particular, the systematic SAR data acquisition enables the build-up of long data time series supporting especially applications such as soil moisture and SAR interferometry (InSAR) surface monitoring. The Sentinel-1 ground coverage and revisit frequency are dramatically improved with respect to the ERS-1/2 SAR and ENVISAT ASAR. The two-satellite constellation offers a six day exact repeat orbit cycle and conflict-free operations based on two main operational modes, that are the Interferometric Wide Swath (IW) and the Wave mode (WV). In comparison with its predecessors the Sentinel-1 mission represents an n-fold evolution of capability. Overview of the field of activity proposed The proposed Young Graduate Trainee’s (YGT) activity will focus on the analysis of SAR data time series acquired by Sentinel-1A and Sentinel-1B (once in orbit) with the objectives: a) to analyse the performance evolution of the Sentinel-1A and Sentinel-1B instruments particularly for the implementation of inter-satellite SAR interferometry and related applications; b) to derive predictions for the end-of-life mission application performance for the constellation; c) to evaluate the adequacy of the Sentinel-1A/-1B SAR system performance for deriving geophysical parameters with sufficient accuracy considering calibration methods and including the implementation of geophysical retrieval algorithms, e.g. for soil moisture estimation, surface displacement mapping and sea-ice classification, and d) to support the Sentinel-1B SAR system calibration and performance verification during the Sentinel-1B inorbit Commissioning by analysing Sentinel-1A &B data. The Young Graduate Trainee will use (and if necessary upgrade) the Sentinel-1 Commissioning Phase Analysis Faciity (CPAF). The CPAF was procured during the Sentinel-1A/-1B development and is used for the end-to-end performance verification and SAR system calibration during ground tests and for in-orbit commissioning activities. Educational and other requirements Applicants should have just completed, or be in their final year of a University course at Master’s Level (or equivalent) in remote sensing, geophysics, electromagnetics or in a related engineering or scientific discipline. Previous experience in SAR remote sensing or radar data processing and calibration or development of geophysical retrieval algorithms, and familiarity with the development of software would be an asset. Applicants should have good interpersonal and communication skills and should be able to work in a multi-cultural environment, both independently and as part of a team. HFC-HO/TO for Young Graduate Trainees/issue 1.2 01/09/2015 Applicants must be fluent in English and/or French, the working languages of the Agency. A good proficiency in English is required. How can I apply? Please fill in the online application form. Please note that only one application may be submitted for the YGT Scheme. The YGT Scheme is open to recently qualified young men and women who are nationals of one of the following states: Austria, Belgium, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland, and the UK, or Canada as a Cooperating State, Bulgaria, Latvia, Lithuania, Slovakia and Slovenia as European Cooperating States (ECS).
