Спутник ДЗЗ. Radarsat 2. [Редактировать]

Этот радарный спутник характеризуется пространственным разрешением от 100 м до 1 м, возможностью съемки во всех возможных поляризационных режимах, широким диапазоном площадей кадров и очень высокой производительностью, а также возможностью мониторинговой съемки через 2-3 дня. По сравнению с предшествующим космическим аппаратом Radarsat-1, новый спутник Radarsat-2 имеет ряд существенных технических усовершенствований:

  • установлен новый радар с активной фазированной антенной решеткой, обеспечивающий съемку с пространственным разрешением до 1-3 м;
  • реализован режим многополяризационной съемки с сигналами двух или четырех видов поляризации одновременно;
  • обеспечена возможность съемки районов с левой и с правой стороны относительно трассы полета, что позволяет сократить время повторного просмотра;
  • увеличена емкость бортового накопителя для выполнения глобальной съемки;
  • увеличена точность определения орбитального положения и ориентации спутника и, как следствие, более точной геопривязки изображений.

12015-07-09. Малазийское агентство заключило три контракта с MDA.
Malaysian Remote Sensing Agency (MRSA), агентство которое работает под руководством Малазийского министерства технологий и инноваций, заключило три контракта с MacDonald, Dettwiler and Associates на получение информации с космического аппарата Radarsat 2. MDA также поставит наземную станцию для работы с аппаратом Radarsat 2, подготовит персонал который будет способен создавать новые продукты на основе данных с аппарата. Кроме этого, компания должна будет до поставки станции обрабатывать заявки малазийского агентства в приоритетном порядке.
MRSA использует спутниковую информацию для решения задач развития экономики страны. Однако, данная организация не является простым оператором, она также проводит разработку различных продуктов в интересах Малазии.Тэги: Malaysian Remote Sensing AgencyRadarsat 2MDA
22015-07-10. Сканекс и MDA провели совместный семинар в Москве.
8 июля в Москве прошел семинар «Радарные технологии RADARSAT для экономики России», организованный ГК «СКАНЭКС» совместно с канадской компанией MDA Geospatial Services — оператором спутниковой радиолокационной программы RADARSAT. Познакомиться с методиками применения радарных данных и реализованными проектами пришли более 40 участников, представляющих компании из разных отраслей экономики.
В ходе семинара специалисты MDA рассказали о программе RADARSAT, особенностях работы радиолокационных спутников и преимуществах использования получаемых с них данных. Особое внимание докладчики уделили возможностям, которые открывает использование радарных данных для мониторинга поверхности морей, ледовой обстановки, паводков и наводнений, детектирования положения морских судов, нефтяных загрязнений, решения задач лесного и сельского хозяйства, нефтяной и газовой промышленности.

32016-03-31. DigitalGlobe купила наземные станции у компании MDA.
MacDonald, Dettwiler and Associates (MDA) получила два контракта от компании DigitalGlobe на поставку наземных станций приема информации в интересах двух иностранных заказчиков. Отличительной особенностью решений от компании MDA является то, что они в основном ориентированными не только на передачу информации в единую систему хранения снимков, но и позволяют осуществлять обработку изображений в режиме реального времени. Также согласно контракту данные станции должны будут уметь принимать информацию от космического аппарата Radarsat 2 и иметь возможности по быстрой адаптации к новым аппаратам оптической и радиолокационной съемки.Тэги: DigitalGlobeRadarsat 2
42017-06-05. Компания DigitalGlobe объявила о планах по расширению информационного содержимого своего хранилища данных.
Компания DigitalGlobe объявила о том, что она начала добавление в свой архив и связанную с ним платформу данных полученных с КА Radarsat-2. По состоянию на 2017 год объем хранимой оператором информации о Земле превысил 100 петабайт изображений, а с расширением объема данных о высоте DigitalGlobe может существенно расширить свое присутствие на рынке пользовательских систем 3-Д моделирования.
Помимо этого компания обнародовала планы по запуску веб приложения, которое будет предоставлять заинтересованным потребителям доступ к часто обновляемым снимкам заранее выбранной области местности. Тэги: DigitalGlobeRadarsat 2
52017-12-14. RADARSAT-2 помог создать перманентную дороге к арктическому океану.
Согласно сообщению космического агентства Канады, в ходе создания новой дороги (Inuvik Tuktoyaktuk Highway) к арктическому океану активно использовались предоставляемые радарным КА RADARSAT-2 возможности по съемке Земли. 138 км хайвей стал первой подобной дорогой, которая позволила стране получить доступ к северному океану. Как ожидает правительство, строительство дороги приведет к тому, что стоимость жизни населения в Tuktoyaktuk упадет на $1.5 млн в год. Также власти страны рассчитывают на то, что новая дорога позволит увеличить количество туристов. Тэги: Radarsat 2
62018-03-29. Компания MDA подписала новые многочисленные контракты на поставку данных с КА Radarsat-2.
Компания MDA объявила о том, что она подписала многочисленные контракты на оказание геоинформационных услуг на основе радиолокационных данных с КА Radarsat 2. В совокупности эти контракты принесли канадской компании около CA$16 млн ($12.4 млн). Согласно обнародованным данным в перечень подписанных контрактов входят:
1. Расширение поставок для EarthStar, которая специализируется на оценке ланшафтных измений по спутниковым снимкам.
2. Продолжение работ с европейским агентством по обеспечению безопасности морских перевозок.
3. Продолжение работ с министерством обороны Канады.
Помимо этого компания заявила о том, что она заключила контракты с большим числом компаний специализирующихся на работах в области добычи нефти и газа.Тэги: MDARadarsat 2
