Спутник ДЗЗ. Ikonos. [Редактировать]

24 сентября 1999 года с космодрома Ванденберг (США, штат Калифорния) был успешно запущен первый в истории человечества коммерческий спутник для съемки Земли со сверхвысоким (лучше 1 м) разрешением – IKONOS. Инициатором использования высокодетальных снимков в гражданских целях выступила компания Space Imaging (с января 2006 г., после слияния с компанией OrbImage, GeoEye). IKONOS передает информацию в панхроматическом режиме с разрешением от 0.8 м и в мультиспектральном (4 канала, аналогичные по спектральным характеристикам Landsat 4&5 TM) с разрешением от 3.2 м. Имеется возможность получения продуктов на основе снимков IKONOS в следующих комбинациях каналов: ч/б, «естественные цвета» (красный, зеленый, голубой каналы), «искусственные цвета» (ближний инфракрасный, красный, зеленый каналы) или все четыре канала. Облетая Землю со скоростью примерно 7 км в секунду, спутник IKONOS собирает данные с площади более 2000 км2 в минуту. C одного витка может быть отснята площадь до 10000 км2. Столь высокая производительность спутника позволяет снимать и получать достаточно точные снимки с высоким разрешением за короткий срок. 

Режимы съемки:

  • кадровый;
  • площадной (мозаичный) до 10 тыс. квадратных километров;
  • маршрутный 11х100 ... 11х1000 квадратных километров;
  • стерео 22х130 км.

12015-05-19. Космический аппарат IKONOS выведен из эксплуатации после 15 летнего срока пребывания на орбите.
Коммерческий космический аппарат IKONOS был выведен спутниковым оператором DigitalGlobe из состава своей орбитальной группировки через 15 лет активного существования на орбите. С момента своего запуска космический аппарат предоставил данные о более чем 400 млн. квадратных километрах поверхности Земли. Тэги: IkonosDigitalGlobe
