Компания SES расширила свое предложение
Цитировать
Компания SES объявила о том, что она увеличила емкость своей среднеорбитальной группировки O3b и теперь может предлагать на 38 процентов больше емкости своим потребителям. Основу для данного расширения составили запущенные при помощи РН Союз-СТ (пуск 9 марта 2018 года) четыре космические аппарата доведшие общее количество аппаратов в группировке до 16 шт. Следующий запуск четырех КА группировки запланирован в первой половине 2019 года, а в 2021 году компания приступит к запуску следующего поколения КА, которые имеют общее название O3b mPOWER.

U.S. FCC расширила возможности использования ОГ O3b
ЦитироватьКомпания SES объявила о том, что она получила от U.S. Federal Communications Commission (FCC) разрешение на право расширенной работы на рынке спутниковой связи США. В частности регулятор разрешил использовать компании дополнительные частоты, что позволит ей осуществить развертывание КА на наклонные и экваториальные орбиты обеспечивая тем самым более полный охват Земли. В общей сложности это решение позволит компании запустить дополнительные 26 аппаратов, что доведет общее количество спутников в группировке до 42 шт.

The SES-14 satellite, misdelivered by Ariane 5 in January, finally arrived on station in geostationary orbit at 39.0W on Jul 17.

ЦитироватьSES wants fleet of identical, interchangeable satellites

PARIS — Fleet operator SES plans to revolutionize satellite purchasing and operations.
Instead of buying individual satellites tailored for a specific job at a precise orbital location as it has for decades, the Luxembourg-based company is seeking homogenous satellites with digitally processed payloads it can reconfigure to perform any job in geostationary or medium Earth orbit.
"We will only buy one type of satellite going forward," Steve Collar, SES president and chief executive, told reporters Sept. 10 at the World Satellite Business Week conference here. "Exactly the same spacecraft can be operated at 19.2 degrees, 23.5 degrees, 108 degrees East, it doesn't matter. We can put them wherever we want."
If the SES board of directors approves the plan, SES will solicit proposals by the end of the month and begin purchasing in early 2019 the new 2.5 to 2.9-ton spacecraft offering approximately 12.5 kilowatts of power, said Martin Halliwell, SES chief technology officer, who leads the initiative.
Prior to announcing its plan, SES worked with 11 potential satellite vendors and selected three for continued cooperation. Company executives declined to name the vendors.
SES is embarking on this campaign because it expects satellites to be an integral part of evolving global communications networks. To perform that role, however, the industry will need to expand satellite production dramatically, Collar said.
"If we get the savings we think we will, we will be able to significantly scale our network without spending more or more modestly scale our network and spend less," Collar said. "We haven't yet decided where that comes out."
To further improve economies of scale, SES is encouraging manufacturers to share the new spacecraft design with other customers. "Let's make the party as big as possible," Halliwell said. Collar added, "We think it will improve the economics of the whole industry."
SES plans to stack three of its future satellites, which don't yet have a brand name, on rockets. The rockets could then drop them off in medium Earth or geostationary transfer orbit, as needed, Halliwell said.
SES operates 56 satellites in geostationary orbit and 16 O3B satellites in medium Earth orbit. The firm plans to launch four more O3B satellites in 2019. SES also is investing more than 1 billion euros ($1.16 billion) in O3B mPower, a seven-satellite constellation built by Boeing for internet and data connectivity that is slated to begin launching in 2021.
SES's plans to begin flying the new reprogrammable satellites after it launches the mPower satellites, Collar said.

ЦитироватьSES-14 Goes Operational to Serve the Americas

Written on 04 Sep 2018

SES's geostationary satellite with its wide-beam and high throughput capabilities will capture attractive growth opportunities in video, maritime and aeronautical markets across the Americas

Luxembourg, 4 September 2018 – SES announced today that the high-powered SES-14 satellite, positioned at 47.5 degrees West, is now serving Latin America, the Caribbean, North America, North Atlantic and West Africa.
Спойлер
The all-electric satellite, which has both C- and Ku-band wide-beam coverage and Ku-band high throughput spot beam coverage, is SES's second hybrid satellite to serve the Americas, with the first being SES-15.

SES-14's C-band and Ku-band wide beams and high throughput capabilities are serving various markets. The satellite is expanding the reach of SES's second cable neighbourhood in Latin America, and provides new capacity for direct-to-home services. It is also delivering more high-speed connectivity to the dynamic aeronautical market and other traffic-intensive applications in the maritime and cellular backhaul markets.

The satellite also carries a hosted payload for NASA's Global-scale Observations of the Limb and Disk (GOLD) mission. GOLD will provide unprecedented imaging of the Earth's upper atmosphere from geostationary orbit to deepen scientists' understanding of the boundary between Earth and space.

SES-14 at 47.5 degrees West is replacing and augmenting services currently provided on NSS-806. The license to operate at this Brazilian orbital location was the result of SES's successful participation in a spectrum auction in 2014.

Martin Halliwell, Chief Technology Officer at SES, said, "Thanks to the Airbus, Arianespace and SES teams, SES-14 is able to fulfil its planned satellite mission of bringing better picture quality TV content to people across Latin America, as well as delivering high-speed broadband services to airline passengers flying over the Americas and North Atlantic routes. Enterprises and communities within the region will also be able to access the reliable connectivity provided by SES-14. SES-14 is key to SES's future growth trajectory and is part of our ongoing strategy to develop innovative capabilities for specific and growing markets."

SES-14 was launched on an Ariane 5 rocket from the Guiana Space Centre in Kourou, French Guiana. SES-14 was built by Airbus Defence and Space and is an all-electric satellite. The satellite also features a Digital Transparent Processor (DTP), which increases payload flexibility and will provide customised connectivity solutions to SES's customers.

.@SES_Satellites selects @AirbusSpace @BoeingSpace @Thales_Alenia_S to compete for next-gen sats w/ non-exclusive design adaptable to any GEO slot, MEO orbit as part of new strategy. Shorter GEO lives, in-orbit servicing no longer viewed as needed.

.@INTELSAT says it will trim capex in coming 3 years with software-defined satellites, refueling/mission-extension vehicles for 2 near-retirement sats, and - memo to @SpaceX @ArianeGroup @blueorigin et al -- use of reusable rockets.

ЦитироватьКомпания SES подтвердила планы по созданию низкоорбитальной группировки
Европейская SES подала заявку в FCC США. Предметом запроса является разрешение на создание и доступ на местный рынок низкоорбитальной группировки из 36 спутников. Как отметили в компании, планируемые к созданию аппараты будут ориентированы на решение задачи передачи цифровых данных. Также компания попросила FCC разрешить ее новым 34 среднеорбитальным спутникам O3b работать на рынке США. Если FCC одобрит это увеличение то услуги среднеорбитальной группировки будут предоставляться на рынке США с использованием 76 аппаратов (20 уже запущено). Также компания подтвердила свои планы по выведению 10 спутников на среднеорбитальную экваториальную орбиту, передает Ecoruspace.
