Спутник навигационных систем. IRNSS 1C. [Редактировать]

IRNSS-1C это третий навигационный спутник из семи запланированных ISRO для создания космического сегмента региональной навигационной системы Индии. Конфигурация IRNSS-1C похожа на IRNSS-1A и IRNSS-1B. Спутник был запущен через шесть месяцев после IRNSS-1B. D В качестве полезной нагрузки аппарата выступают навигационные и измерительные инструменты.. Навигационная нагрузка передает сигналы которые доступны всем пользователям. Эта полезная нагрузка работает в L5-диапазоне (1176.45 MHz) и S диапазоне (2492.028 MHz). В качестве эталона времени выступают рубидиевые атомные часы. Измерительная полезная нагрузка аппарата состоит из C-диапазонного транспондера с помощью которого измеряется расстояние до космического аппарата. IRNSS-1C также оснащен рефлекторами для лазерного измерения позиции аппарата.
