Спутник связи. Anik-G1. [Редактировать]

На КА установлены 24 ретранслятора диапазона С и 28 ретрансляторов диапазона Ku, которые полностью арендованы на 15 лет канадской компанией спутникового телевещания Shaw Direct. КА Anik-G1 планируется эксплуатировать в орбитальной позиции 107,3° з.д. Ожидается, что с помощью ретрансляторов диапазонов С и Ku спутника Anik-G1 суммарная пропускная способность спутников компании Telesat увеличится более чем в два раза. На спутнике Anik-G1 установлено также три ретранслятора диапазона Х, которые на 15 лет арендованы компанией Astrium Services. Кроме того, компания Astrium Services по контракту до 2022 года арендует каналы связи диапазона Х на военной спутниковой системе Skynet (Великобритания). Всего эта компания арендует 75 ретрансляторов диапазона Х с общей пропускной способностью 2,2 ГГц и стала почти глобальной по ретрансляции в этом диапазоне от 180° з.д. до 135° в.д. со значительным покрытием Тихого океана от Гавайских островов до о. Пасхи. Коммерческая эксплуатация четвертого спутника Skynet-5D начата 2 апреля 2013 года в орбитальной позиции 53° в.д. Объем топливных баков на КА Skynet-5D больше, чем на предшествующих КА, что дает возможность менять его ОП в зависимости от требований обстановки.

12015-03-16. Airbus осуществила маневр по переводу аппарата Skynet 5a в новую орбитальную позицию.
Airbus Defence and Space 16 марта переместила военный аппарат связи Skynet 5A (работает в X-диапазоне), чтобы обеспечить компании почти глобальный охват военных пользователей. Перемещение осуществленно с разрешения Министерства обороны Великобритании. Новая позиция аппарата 165 градусов восток. Airbus Defence and Space также арендовал все емкость X-диапазона на аппарате Anik G1. Однако в компании отметили, что спутник Anik G1 обладает малой мощностью и не осуществляет шифрование данных, кроме этого он не способен противостоять помехам, что для военных потребителей не является приемлимым.Тэги: Skynet 5AAirbus GroupAnik-G1Министерство обороны Великобритании

TELESAT TO LAUNCH NEW ANIK G1 SATELLITE FOR SHAW DIRECT OTTAWA, CANADA, March 31, 2010 – Telesat, the world’s fourth largest fixed satellite services operator, announced today that it has completed an agreement for a new satellite with one of its key customers, Shaw Direct. Shaw Direct, a leading provider of direct-to-home satellite television services in Canada, has agreed to utilize a payload on a new Telesat satellite called Anik G1. Anik G1 is planned to commence construction in the second quarter of 2010 and enter commercial service in the second half of 2012. The Shaw Direct payload on Anik G1 will consist of sixteen national transponders operating in the extended Ku-band frequencies that will augment Shaw Direct’s capacity and capabilities at its prime orbital location of 107.3 degrees West Longitude for the anticipated 15-year life of the satellite. “We are delighted that Shaw Direct has chosen Telesat to provide the satellite capacity needed to expand its high quality video service offerings,” said Dan Goldberg, Telesat’s President and CEO. “The ability of Telesat and Shaw to make the substantial investments associated with Anik G1 is the result of Industry Canada’s recent decision to make extended Ku-band available for direct-to-home television services, a decision that allows our companies to expand the delivery of advanced video services to all Canadians and enhances competition in Canada.” In addition to the Shaw Direct capacity, Anik G1 will carry additional payloads to serve other markets. Telesat expects to announce the selected manufacturer of this new satellite in the next two to three months. About Telesat (www.telesat.com) Headquartered in Ottawa, Canada, with offices and facilities around the world, Telesat is the fourth largest fixed satellite services operator. The company provides reliable and secure satellite-delivered communications solutions to broadcast, telecom, corporate and government customers.
