Спутник связи. Inmarsat 4A-F4. [Редактировать]

КА Alphasat-I-XL пятого поколения является первым спутником, изготовленным на спутниковой платформе (СП) Alphabus, которая разработана французским и европейскими космическими агентствами. На СП Alphabus  компаниями Astrium Satellite и Thales Alenia Space при финансировании Агентства ESA и Космического агентства Франции CNES были установлены четыре демонстрационных ПГ. Консорциум Inmarsat разрешил Агентству ESA в течение 3 лет продолжать испытания технологических ПГ на КА Alphasat. В их число входят испытания лазерных связных терминальных устройств, результаты которых будут использованы в создании коммерческой глобальной системы передачи данных. На частотах диапазонов Q и V будут испытаны перспективные радиосвязные устройства, а новый астродатчик оснащен детектором с активными пикселями. КА Alphasat дополнит пропускную способность системы Inmarsat на частотах диапазона L (широкополосный растянутый) в орбитальной позиции 25° в.д. Расчетный срок активного существования спутника – 15 лет.

Аппарат куплен консорциумом Inmarsat с целью добавить пропускную способность к своему основному бизнесу на частотах диапазона L. Спутник планируется эксплуатировать в орбитальной позиции (ОП) 25° в.д., где в настоящее время работает КА Inmarsat-4F. Через 6 месяцев испытаний на орбите КА Alphasat-I-XL займет ОП 25° в.д. и будет использоваться для обслуживания абонентов по 400 остронаправленным лучам, а КА Inmarsat-4F будет переведен в новую ОП с целью расширения зоны покрытия. В спутнике Alphasat-I-XL используется разработанный компанией Astrium цифровой процессор обработки сигнала. Фактически в нем объединено 8 процессоров обработки сигнала, которые разделены на две группы, по 4 процессора в каждой. Общая масса процессора 250 кг. Каждый из процессоров состоит из 17 базовых компьютеров. Скорость выполнения операций – 2 трлн/c. В зону обслуживания КА Alphasat-I-XL войдут страны Африки, Среднего Востока, большинство стран Европы и Центральной Азии.

Некоторые технологические разработки, сделанные по обобщенному проекту Alphabus/Alphasat, уже используются в коммерческих спутниковых платформах компаний Astrium Satellites и Thales Alenia Space. К новым технологиям относятся: 100-вольтовый регулятор снабжения энергией, который компания Astrium включила в линию производства по программе Eurostar; разработанная французской компанией Snecma плазменно-электрическая двигательная система PPS 1350; и связная модульная структура, обеспечивающая для тяжелых полезных грузов совместимость с главной структурой спутника.

Для операторов других коммерческих спутниковых систем связи приобретение цифровых процессоров обработки сигнала затруднительно ввиду их высокой стоимости, поэтому они заказывают спутники с ретрансляторами без преобразования сигнала на борту.

12014-12-25. В испытаниях прототипа L-диапазонного терминала Inmarsat достиг скорости 10 Мбит в секунду при работе с малой антенной L диапазона КА Alphasat I-4A F4. Данный результат позволит фирме выйти на рынок трансляции изображений в режиме реального времени.Тэги: InmarsatInmarsat 4A-F4
22017-06-12. ЕКА провело очередное тестирование системы лазерной передачи информации.
Космическое агентство Европы объявило о том, что ему удалось осуществить передачу данных с космического аппарата Sentinel-2B на космический аппарат Alphasat 1-XL с использование системы лазерной связи (пропускная способность 2 гбит в секунду). Общее время, которое прошло с момента получения снимка, до его передачи на Землю, составило около шести минут. При этом, снимаемая территория находилась в Европе, а данные были переданы в Северную Америку.Тэги: Sentinel 2BInmarsat 4A-F4Европейское космическое агентство
