Спутник технологический. AISSat 1. [Редактировать]

Космический аппарат “AISSat 1” является тестовым изделием, которое должно продемонстрировать возможности реализации приема AIS сообщений при помощи малого аппарата. В целом результаты эксперимента оказались положительными поэтому в дальнейшем на орбиту были выведены еще несколько подобных аппаратов.
