Спутник связи. TDRS-H. [Редактировать]

TDRS-H является первым в серии из трех КА нового поколения (в нее также входят TDRS-I и TDRS-J). Все три аппарата разработаны компанией Hughes Space and Communications (HSC) по контракту с NASA.  КА собран на предприятии компании в г. Эль-Сегундо, шт. Калифорния. В качестве основы аппарата использовалась платформа BSS-601.  При заказе новой серии КА TDRS NASA решило использовать при построении работы с исполнителем ряда коммерческих подходов, а именно:

  • Не стало разрабатывать подробную спецификацию изделия, ограничевшись только выдачей требуемых эксплутационных характеристик.
  • Предусмотрело наличие штрафных санкций. Более того, если в течении первых двух лет количество отказов превысит  9, то компания должна будет предоставить новый аппарат.
