Спутник ДЗЗ. CBERS 2B. [Редактировать]

По данным агентства Синьхуа, 19 сентября в 11:26 по Пекинскому времени (03:26 UTC) в Китае выведен на орбиту третий спутник съемки Земли CBERS-2B, созданный по совместной китайско-бразильской программе. Запуск осуществлен с помощью ракеты-носителя «Великий Поход-4В» (CZ-4) с полигона ракетно-космического центра Тайюань в провинции Шаньси. Спутник успешно выведен на солнечно-синхронную орбиту. Бортовая аппаратура CBERS-2B работает штатном режиме. Разработкой спутника руководили Китайская академия космической техники (CAST - Chinese Academy of Space Technology) и бразильский институт INPE, где были осуществлены сборка и тестирование спутника перед отправкой на полигон в Китай.
Конструктивно новый спутник идентичен предшествующему космическому аппарату CBERS-2A , но оснащен новой камерой высокого разрешения HRC. Всего на спутнике установлены три взаимодополняющие оптико-электронные системы низкого, среднего и высокого пространственного разрешения, которые получили наименования WFI, CCD и HRC.
Двухканальная система WFI предназначена для получения интегральных характеристик состояния растительности с периодичностью раз в 5 суток, обеспечивает съемку с разрешением 260 метров в полосе шириной 890 км.
Пятиканальная камера CCD обеспечивает съемку с разрешением 20 метров в полосе шириной 113 км и может по командам отклоняться на угол до 32 градусов от надира.
Новая панхроматическая камера HRC детальной съемки впервые установлена на CBERS-2B вместо старой системы IRMSS и позволяет получать изображения с пространственным разрешением до 2,7 метров в кадре шириной 27 км.
По функциональности спутник CBERS-2B с тремя камерами различного пространственного разрешения приближается к известным спутникам IRS-P5 Resourcesat-1, IRS-1C/1D (Индия) и SPOT-5 (Франция).
Сочетание сканеров с различным разрешением и полосой съемки обеспечивает высокую оперативность наблюдения и позволяет расширить перечень решаемых задач: сельское и лесное хозяйство, рациональное природопользование, экологический и природоохранный мониторинг, планирование застройки и др.
