Спутник связи. Protostar 2. [Редактировать]

ProtoStar 2 / IndoStar 2 – второй космический аппарат (КА) орбитальной группировки оператора ProtoStar, который заменил находящийся на орбите спутник Cakrawarta 1. Новый спутник обеспечил прямое телевещание и другие услуги связи, включая широкополосный доступ в Интернет, на территории Индонезии, Индии, Филиппин и Тайваня. 
На спутнике, изготовленном на базе платформы Boeing 601 HP, установлены транспондеры S- и Ku-диапазонов, которые значительно увеличат орбитальную емкость компании ProtoStar. Этот аппарат стал самым мощным в группировке ProtoStar, вырабатывая почти 10 кВт мощности. 
Полезная нагрузка S-диапазона включает 10 активных и 3 запасных усилителя на лампе бегущей волны. По соглашению с ProtoStar индонезийский оператор Indovision предоставляет услуги непосредственного телевизионного вещания (DTH) в S-диапазоне для Индонезии. 
Первая полезная нагрузка Ku-диапазона предназначена для непосредственного телевизионного вещания и других услуг связи на территории Индии. Вторая полезная нагрузка Ku-диапазона может переключаться между Филиппинами, Индонезией и Тайванем для обеспечения доступа в Интернет и других коммуникационных услуг.
