Спутник ДЗЗ. RapidEye-E. [Редактировать]

RapidEye — группировка из пяти мини-спутников, предназначенная для решения наблюдательных задач во многих отраслях. Каждый из пяти спутников оснащён мультиспектральной оптико-электронной камерой производства Jena-Optronik GmbH (Германия) для съёмки с пространственным разрешением 6,5 м. Каждый спутник весит 150 кг. Спутники равномерно распределены на орбите. Они облетают Землю с севера на юг и пересекают экватор в 11 часов по местному солнечному времени с дистанцией около 660 км и интервалом в 20 минут. Съёмка выполняется сеансами с максимальной длиной полосы в 3000 км. В пределах одного сеанса спутник может снять участок поверхности Земли шириной 77 км и длиной до 1500 км, что обеспечивает ежедневную съёмку площадью в 5 млн км².

Analyzing over an entire year helps minimize this effect.  The RapidEye fleet has been quite stable since starting operations.  Maximum drop for one satellite-band is RE 4 Band 4 (3.90%)  All  Satellite Bands agree well with each other. Maximum difference between Satellites is in Band 4 (3.24%).  All degradations are accounted for in RapidEye products.
