Спутник ДЗЗ. Kompsat 3A. [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.
