Спутник ДЗЗ. Kompsat 3. [Редактировать]

КА KOMPSAT-3 и KOMPSAT-3A являются продолжением миссии корейских спутников наблюдения Земли KOMPSAT (Korean Multi-Purpose Satellite). Они идентичны по своим техническим характеристикам и предназначены для получения цифровых изображений земной поверхности с пространственным разрешением 0,7 м в панхроматическом режиме и 2,8 м в мультиспектральном режиме.

Решаемые задачи:

  • создание и обновление топографических и специальных карт и планов вплоть до масштаба 1:10 000;
  • инвентаризация и контроль строительства объектов инфраструктуры транспортировки и добычи нефти и газа;
  • выполнение лесоустроительных работ, инвентаризация и оценка состояния лесов;
  • инвентаризация сельскохозяйственных угодий, создание планов землепользования, точное земледелие; обновление топографической подосновы для разработки проектов генеральных планов перспективного развития городов, схем территориального планирования муниципальных районов;
  • инвентаризация и мониторинг состояния транспортных, энергетических, информационных коммуникаций; широкий круг задач в области охраны окружающей среды.

12016-07-06. SI Imaging Services начала продажи 50 см снимков.
Компания SI Imaging Services выполнила свои майские обещания и вышла на рынок коммерческих поставок ДЗЗ со своим новым продуктом, который имеет разрешение около 50см. Источником получения снимков ДЗЗ является запущенный 2015 году космический аппарат Kompsat-3A. Таким образом, американская Digital Globe получила в лице южнокорейской компании своего первого конкурента, который может составить ей реальную конкуренцию, даже не смотря на то, что с запуском космического аппарата WorldView 4 компания из США заявила о возможной продаже на рынке панхроматических изображений с разрешением около 25 см. Вместе с тем, необходимо отметить, что подобный показатель является достаточно близким к теоретическому пределу в 15-20 см и достигается только при пост обработке информации. Аналогичным образом, скорее всего, поступает и южнокорейский оператор, поскольку ранее он объявлял о том, что его аппараты снимают с разрешающей способностью около 70 см.

22016-10-27. Компания Thales Alenia Space получила контракт от KARI.
Европейская Thales Alenia Space объявила о том, что она получила контракт от космического агентства Южной Кореи (KARI, Korea Aerospace Research Institute) на поставку спутниковой навигационной системы KASS (Korea Augmentation Satellite System).
В своем сообщении европейский производитель отметил, что данная деятельность получила сильную поддержку со стороны Европейской Комиссии, GSA (GNSS Supervisory Authority), ЕКА, EASA (European Aviation Safety Agency) и космического агентства Франции.
Со стороны Южной Кореи основным потребителем услуг системы спутникового дополнения навигационных систем будет являться министерство Земли, инфраструктуры и транспорта (MOLIT), которое обосновало выбор изготовителя тем, что европейская компания хорошо себя зарекомендовала в качестве головного исполнителя проекта EGNOS.
Навигационная система KASS должна будет согласно контракту позволить Южной корее значительно улучшить на соей территории качество работы таких навигационных систем как ГЛОНАСС, Галилео и GPS (точность определения координат должна будет в среднем составлять не более одного метра). Якрным потребителем новой системы станут организации обеспечивающие безопасность аиаперелетов.Тэги: Навигационная система Южной КореиThales Alenia SpaceKompsat 3
32016-12-15. Thales поставила элементы космических аппаратов серии Geo-Kompsat-2.
Испанское подразделение Thales Alenia Space поставило вторую из трех панелей (габариты 3х3 метра), которые будут использоваться при построении КА серии GEOKOMPSAT-2. Космические аппараты GEO-KOMPSAT-2 (Geostationary Earth Orbit Korea Multi-Purpose Satellite) рассматриваются Южной Кореей как ключевой элемент национальной программы развития метеоспутников. Как ожидает KARI, каждый из аппаратов (GEO-KOMPSAT-2A/B) будет весить 3.5 тонн. Запуск КА намечен на 2018 и 2019 годы. Thales Alenia Space в рамках проекта отвечает за производство коммуникационной полезной нагрузки двух КА. Тэги: Geo-Kompsat-2Thales Alenia SpaceKompsat 3
42017-03-09. Mohammed bin Rashid Space Center и KARI пописали Меморандум о взаимопонимании.
Mohammed bin Rashid Space Center (MBRSC) подписал Меморандум о взаимопонимании с Korea Aerospace Research Institute (KARI). В рамках данного документа стороны договорились о том, что они будут сотрудничать как при осуществлении космической деятельности, так и продолжат трансферт технологий.

52017-04-18. Европейская Thales Alenia Space закончила поставки телекоммуникационного оборудования в интересах КА серии GEO-KOMPSAT-2.
Согласно сообщению компании, европейский производитель осуществил поставку третей коммуникационной панели в интересах создания двух КА серии Geo-Kompsat-2. Поставленное изделие будет установлено ка космический аппарат GEO-KOMPSAT-2В.
Всего компания произвела и протестировала в Испании три подобные панели, две из которых создавались для КА GEO-KOMPSAT-2А.
Система GEO-KOMPSAT-2 (Geostationary Earth Orbit Korea Multi-Purpose Satellite) это один из ключевых проектов южнокорейской программы создания системы наблюдения за Землей в интересах метеорологии. Каждый из КА должен будет весить около 3.5 тонн и работать на геостационарной орбите.Тэги: Geo-Kompsat-2Thales Alenia SpaceKompsat 3
