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.

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
