12015-07-09. Airbus Defence and Space подписала первый контракт на полностью переконфигурируемый космический аппарат.
Airbus Defence and Space выиграла первый контракт на полностью переконфигурируемый космический аппарат (в настоящее время называется Quantum). Заказчиками проекта выступили Европейское космическое агентство и спутниковый оператор Eutelsat.
Особенностью аппарата является его возможность адаптироваться к изменению зоны покрытия, емкости и диапазону вещания. Также аппарат будет способен менять орбитальную позицию. Таким образом, компания Airbus возможно станет первой компанией которая создаст спутник связи который станет полностью серийным и не будет требовать доработок под конкретного заказчика. Новый спутник будет работать в Ku-диапазоне. САС аппарата планируется на уровне 15-и лет. Местом сборки спутника определена фабрика в Великобритании.
Также компания объявила о том, что, космический аппарат EutelSat 172B будет полностью электрическим.Тэги: QuantumAirbus GroupEutelsat Communications S.A.EutelSat 172B
22016-01-08. Компания Anaren выиграла $7 млн. контракт в рамках программы Eutelsat Quantum.
Компания Airbus Defence and Space заключила $7 млн. контракт с компанией Anaren в целях создания усовершенствованной системы формирования лучей космических аппаратов связи. В случае успешной разработки Airbus планирует устанавливать разработанную систему на свои перспективные полностью реконфигурируемые космические аппараты. Новый тип спутников связи разрабатывается в рамках программы Eutelsat Quantum которая финансируется как компанией Eutelsat, так и европейским космическим агентством.Согласно контракту срок поставки первого летного экземпляра системы составляет 2017 год.

32017-05-24. Компания Eutelsat закажет дополнительные два КА серии Quantum.
Компания Eutelsat обнародовала данные о планах купить еще два космических аппарата серии Quantum. Первый аппарат серии был куплен оператором у Airbus в 2015 году за $198 млн. (запуск КА должен состояться в 2019 году) При этом, к настоящему времени компания уже успела предпродать порядка 50 процентов от емкости нового спутника.
К особенностям серии Quantum производитель относит:
1. Возможность полной перенастройки спутника путем изменения его программного обеспечения.
2. Использование фазированной антенны, которая позволит адаптировать спутник под требования рынка (поставщик компонентов Анарен). При этом, согласно заявлению Airbus использование данной технологии позволит создавать спутники без заранее определенной зоны покрытия.
3. Емкость КА должна будет составить восемь одно гигагерцовых луча на передачу данных. При этом, каждый луч будет способен изменять свою зону покрытия от одной трети Земли до 600 км.
4. Потребители аппарат будут иметь возможность разделять лучи на составляющие, которые будут способны следовать за передвигающимся объектом.
5. Текущее поколение аппаратов Quantum будет работать в Ku диапазоне, однако в дальнейшем будут созданы и Ка диапазонные аппараты.
6. Технологически спутник унаследовал многие свои свойства от военных КА геостационарной связи.
7. За счет использования фазированной антенны спутники Quantum будут способны определять источники радиопомех с точностью до 20 км. При этом, КА будет способен либо ограничивать вещание на регион с радиопомехами либо менять частоту передачи данных. Тэги: QuantumAirbus Group
