Спутник навигационных систем. IRNSS 1B. [Редактировать]

IRNSS-1B это второй из семи запланированных спутников космического сегмента региональной навигационной системы Индии. Конфигурация аппарата похожа на конструкцию IRNSS-1A. Спутник был запущен через семь месяцев после запуска IRNSS-1А. Две солнечные батареи состоят из Ultra Triple Junction солнечных ячеек. Аппарат оснащен солнечными и звездными датчиками, а также гироскопами для ориентации аппарата в пространстве. Для аппарата была разработана специальная система теплозащиты атомного стандарта времени. Система ориентации и стабилизации работает на основе маховиков, магнетометров и ускорителей. Двигательная установка аппарата состоит из жидкостного апогейного двигателя и ускорителей.  После размещения на целевую орбиту две солнечные панели раскрываются и управление аппаратом переходит к производителю под руководством которого аппарат выполняет маневры по окончательному размещению аппарата на орбите.
