Спутник ФКИ. GOCE. [Редактировать]

Научно-исследовательский спутник, проект ЕКА. Главной полезной нагрузкой спутника был электростатический гравитационный градиометр, состоявший из 6 акселерометров и предназначавшийся для изучения гравитационного поля Земли и геоида. Стрелообразная форма спутника, а также его «плавники», помогали спутнику сохранять ориентацию и уменьшали торможение в верхней атмосфере, которое довольно значительно на высоте его орбиты — около 260 км. Низкая орбита спутника и высокая точность акселерометров в 10-12 м/с2 позволили к окончанию наблюдений улучшить точность определения геоида до 1—2 см на масштабах порядка 100 км. Для компенсации атмосферного торможения и других негравитационных воздействий на спутнике был установлен непрерывно работавший ионный двигатель, использовавший для создания импульса ионизированные атомы ксенона. Данные со спутника GOCE нашли многочисленные применения, в том числе при изучении опасных вулканических регионов и прояснении поведения океана. Динамика океана являлась одной из главных целей спутника. Сопоставляя полученную информацию о форме геоида с информацией о высоте поверхности океана, полученной высотометрическими спутниками, учёные смогли проследить направление и скорость геострофических океанских течений.

22013-11-11. Аппарат окончил свое активное существование.
GOCE - европейский КА, предназначенный для исследования гравитационного поля Земли и стационарной циркуляции океана в рамках проекта ЕКА «Живая планета», был запущен 18.03.2009 с космодрома Плесецк ракетой-носителем «Рокот» и выведен на орбиту 290×272 км и наклонением 96.55 º. КА «GOCE» имел примерно цилиндрическую форму с диаметром ~1 м и длиной ~5 м. Масса КА составляла более 1 т. В период с 21 октября по 11 ноября 2013 года под эгидой Межагентсткого координационного комитета по космическому мусору (МККМ) была проведена международная тестовая кампания по сопровождению схода с орбиты космического аппарат «GOCE». Тестовая компания была 16-ой по счету, в ней приняли участие 11 из 12 космических агентств – членов МККМ. Головную координирующую роль в данных работах со стороны Роскосмоса традиционно выполнял ЦУП ФГУП ЦНИИмаш с привлечением кооперации организаций. По данным USSTRATCOM космический объект № 34602 в каталоге NORAD достиг высоты 80 км 11.11.2013 в 00:16:00 UTC +/- 1 мин. в точке с координатами 56,0°ю.ш., 60,0°з.д. Тэги: GOCE
