Спутник связи. Nimiq 4. [Редактировать]

Nimiq 4 – это новый телекоммуникационный спутник, предназначенный для улучшения телевизионного вещания на территории Канады. Космический аппарат (КА) Nimiq 4 принадлежит компании Telesat Canada – национальному канадскому оператору спутниковой связи, обеспечивающему передачу данных и предоставляющему услуги радиопередачи в Северной Америке.
Космический аппарат будет установлен в точке стояния 82° западной долготы как минимум на 15 лет.
Спутник Nimiq 4 построен на базе спутниковой платформы Eurostar E3000S европейской компанией EADS Astrium и предназначен для работы на геостационарной орбите. На аппарате массой около 4850 кг установлены 32 мощных транспондера Ku-диапазона и 8 транспондеров Ka-диапазона. Многоцелевые узконаправленные антенны Ka-диапазона обеспечат вещание на наиболее населенные регионы Канады. В соответствии с конфигурацией платформы спутник оборудован чисто химической двигательной установкой и ионно-литиевыми аккумуляторами. Ранее на этой же платформе были созданы КА Anik F1R и Anik F3, также принадлежащие компании Telesat.

TELESAT SUCCESSFULLY LAUNCHES NIMIQ 5 BROADCAST SATELLITE All Ku-band Payload to Support Growing Demand for Direct-to-Home TV Services in North America BAIKONUR COSMODROME, Kazakhstan, September 18, 2009 – Telesat, the world’s fourth largest fixed satellite services operator, has successfully launched its state-of-the-art Nimiq 5 satellite. Nimiq 5 will utilize 32 high-powered Ku-band transponders to deliver a wide range of high definition and direct-to-home television services across a broad footprint covering Canada and the United States. “The launch of Nimiq 5 underscores Telesat’s commitment to bring the most advanced video programming to North American consumers,” said Dan Goldberg, President and CEO of Telesat. “Nimiq 5 will contribute significant revenue and EBITDA to our results and builds upon our already strong relationship with EchoStar. We greatly value the trust EchoStar has placed in Telesat and look forward to delivering the quality and reliability over the life of Nimiq 5 they have come to expect from Telesat.” Nimiq 5 was launched on an ILS Proton Breeze M rocket from the Baikonur Cosmodrome in the Republic of Kazakhstan at 1:19 a.m. today local time. International Launch Services (ILS) provided mission and launch services. The satellite separated from the upper stage of the rocket and the signal was acquired by Telesat’s tracking station in Perth, Australia just over nine hours later. Manufactured by Space Systems/Loral, Nimiq 5 will utilize SS/L’s space-proven 1300 platform and enter into commercial service at 72.7 degrees West after it has successfully completed orbit raising and comprehensive in-orbit testing. Nimiq 5 has a solar array span of 26 meters, an expected 15 year mission life and a launch mass of approximately 4745 kg. 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.
