Спутник ДЗЗ. TopSat. [Редактировать]

Британский спутник TopSat представляет собой демонстрационный малый КА по оперативному наблюдению за земной поверхностью в военных целях, а также для экспериментальной отработки новых спутниковых технологий. Проект TopSat финансируется Министерством обороны и Британским национальным космическим центром BNSC (British National Space Centre) в рамках программы MOSAIC (Microsatellite Applications in Collaboration) по использованию микроспутников. Эксперимент TopSat призван показать, что микроспутник способен по оперативному заданию получать изображения в высоком разрешении(2.5 м) и передавать их непосредственно на мобильные наземные станции той же зоны.
