Спутник связи. Anik F1. [Редактировать]

Аппарат был запущен 21 ноября 2000 года на ракете-носителе Ariane 4 с космодрома Куру. На момент запуска, это был самый мощный телекоммуникационный спутник, из когда-либо построенных. Он был оборудован ксеноновым ионным двигателем и вел передачу сигнала на Северную и Центральную Америку. Солнечные батареи на Anik F1 деградировали быстрее, чем ожидалось, поэтому в 2005 году был запущен спутник Anik F1R на который переключили все сервисы с Anik F1. Сейчас Anik F1 предоставляет услуги только для клиентов в Южной Америке.
