Спутник технологический. Nodes 2. [Редактировать]

Космические аппараты НАСА Nodes (Network & Operation Demonstration Satellite) созданы с целью осуществления миссии по демонстрации возможности организации сетей передачи данных между аппаратами. Всего в ходе реализации программы планируется осуществить запуск двух 1.5 юнитовых кубсатов каждый из которых весит до 2 кг. и имеет размеры 10х10х17 см. Технологически данные спутники наследуют свое программное обеспечение и начинку от научно-технического задела созданного в рамках проекта EDSN.Таким образом, они являются конструктивно схожими с данными космическими аппаратами. В качестве программного обеспечения на спутниках установлена система Андроид, а управление осуществляется при помощи специально написанных под эту операционную систему программ.
В ходе полета космические аппараты должны будут:

  • Передавать и ретранслировать данные как между собой так и на Землю.
  • Собирать и передавать данные о солнечной радиации на уровне 400 км. над поверхностью Земли.
  • Автоматически определять тот аппарат который находится в зоне радиовидимости.
