Спутник связи. Galaxy 3C. [Редактировать]

Космический аппарат связи Galaxy3C создан фирмой Boeing Satellite Systems на базе платформы ВSS-702. Срок работы аппарата на геостационарной орбите должен составить 15 лет.После перехода в точку стояния 95°з.д. спутник обеспечит телевещание в различных режимах (эфирное, абонентное и кабельное телевидение), доступ в Интернет, а также передачу данных в видео и аудиорежиме для абонентов в США и странах Латинской Америки.
