Спутник ДЗЗ. Sentinel 2A. [Редактировать]

Sentinel-2 будет оснащен оптико-электронным мультиспектральным сенсором для съемок с разрешением от 10 до 60 м в видимой, ближней инфракрасной (VNIR) и коротковолновой инфракрасной (SWIR) зонах спектра, включающих в себя 13 спектральных каналов, что гарантирует отображение различий в состоянии растительности, в том числе и временные изменения, а также сводит к минимуму влияние на качество съемки атмосферы. Орбита высотой в среднем 785 км, наличие в миссии двух спутников позволит проводить повторные съемки каждые 5 дней на экваторе и каждые 2–3 дня в средних широтах. Первый спутник планируется запустить в 2013 г. Увеличение ширины полосы обзора наряду с высокой повторяемостью съемок позволит отслеживать быстро изменяющиеся процессы, например изменение характера растительности в течение вегетационного периода. Данные Sentinel-2 будут обеспечивать сервисы GMES, связанные, например, с управлением земельными ресурсами, сельскохозяйственным производством и лесным хозяйством, а также мониторингом стихийных бедствий и гуманитарных операций. Уникальность миссии Sentinel-2 связана с сочетанием большого территориального охвата, частых повторных съемок и, как следствие, систематическим получением полного покрытия всей Земли мультиспектральной съем- кой высокого разрешения.
