Спутник навигационных систем. IRNSS 1A. [Редактировать]

Стартовая масса КА IRNSS-1A, созданного на спутниковой платформе I-1K, – 1425 кг, сухая масса – 614 кг. Спутник отделился от РН примерно в Т+20′ на высоте около 500 км. Далее КА был выведен на геосинхронную орбиту с апогеем 20650 км, перигеем 284 км, наклонением 17,86º. После запуска КА IRNSS-1 будет испытываться на орбите в течение четырех месяцев. Расчетный срок активного существования – 10 лет.

Запуск второго КА системы IRNSS планируется через три месяца после ввода в эксплуатацию первого КА, а остальные пять аппаратов предполагается запустить в 2014-2015 гг. Семь КА системы IRNSS будут включать три спутника на геостационарной орбите (в орбитальных позициях (ОП) 34º, 83º и 132º в.д.) и две пары КА на геосинхронных орбитах в ОП 55º и 111º в.д.. В частности, первый и второй КА займут положение в ОП 55º в.д.
