PARIS — Satellite fleet operator SES has awarded Boeing a contract to build seven satellites as part of SES's second-generation medium-Earth-orbit constellation, formerly known as O3b, according to industry officials.
The selection of Boeing Satellite Systems International is a blow for O3b's incumbent prime contractor, Thales Alenia Space of France and Italy, which built all 12 O3b satellites currently in orbit and has eight more under construction.
It is also something of a revenge for Boeing after Thales Alenia Space's win of a contract to build London-based Inmarsat's fifth Global Xpress Ka-band broadband satellite. Boeing built the first four Global Xpress spacecraft.

"The selection of Boeing is an illustration of how different the second-generation O3b will be compared to the first," said one industry official. "SES is heading in a different direction with this. These are very high-throughput satellites, making it a terabit-per-second constellation."
The SES-Boeing contract is expected to be announced in Paris on Sept. 11 as part of Euroconsult's World Satellite Business Week.
SES has targeted the U.S. government, and specifically the U.S. Department of Defense, as a major future customer for O3b, but industry officials said there is no take-or-pay element to the SES-Boeing contract. Boeing's Global Xpress contract with Inmarsat includes a take-or-pay provision under which Boeing guaranteed a certain volume of U.S. government business to Inmarsat and must pay Inmarsat from its own pocket if the volume falls short of actual sales.

SES believes its O3b medium-Earth-orbit constellation provides a complement to its 50-satellite fleet in higher geostationary orbit that will help boost its sales to the U.S. Department of Defense. O3b satellites can dedicate an entire beam to following an aircraft carrier, for example, passing the signal from satellite to satellite as the ship moves. Credit: SES
Each Boeing satellite is expected to weigh some 1,200 kilograms at launch — much heavier than the current 700-kilogram O3b spacecraft despite the use of an all-electric propulsion system. The seven satellites are scheduled for launch starting in 2021.
The current constellation operates in an equatorial orbit some 8,000 kilometers in altitude — an unusual orbit that trains O3b's Ka-band spot beams on territories around the equator to provide broadband connectivity.
The second-generation version is designed to expand into a wider swath of Ka-band from the same orbit, with a second orbit to provide near-global coverage from higher inclination relative to the equator. It would fly at the same approximate altitude, but with these future satellites at a 70-degree inclination relative to the equator.
SES has told the U.S. Federal Communications Commission (FCC) that it would launch up to 24 satellites as part of the second generation in equatorial orbit. Boeing's is the first seven of these. The company has said its higher-inclination system would feature up to 16 satellites.
One industry official said that, in keeping with a recent industry trend of forcing satellite builders to accept tougher contract terms and conditions, Boeing's contract payments will be back-loaded.

SES plans to spend 1.43 billion euros ($1.63 billion) on new satellites and launch services in the next five years. The company has told investors to expect that future satellites are as likely to be in the medium-Earth orbit used by the company's current 12-satellite O3b/SES Networks constellation as in geostationary orbit.

SES has been telling investors for the past year that medium-Earth-orbit offers a major growth opportunity that will not cannibalize the geostationary satellites' revenue stream. While promising investors that its capital spending will drop in the coming years, SES has announced plans to spend 1.43 billion euros ($1.63 billion) on placing new satellites into orbit between 2017 and 2021, with medium-Earth orbit taking a sizable share of the total.
SES Chief Executive Karim Michel Sabbagh has said the O3b architecture can be scaled to meet demand without locking the company into a commitment over 15 years as is the case for large geostationary-orbit satellites. Sabbagh has said medium-Earth orbit offers many of the advantages of low-orbiting systems, including low signal latency, without the drawback of having to cover the entire world and thus wasting part of each satellite's orbit over unpopulated areas.

ЦитироватьSES orders seven satellites fr om Boeing to help meet growing broadband demand
September 12, 2017 Stephen Clark

Forecasting a future wh ere satellite networks reach into vastly more ships, airplanes, homes and businesses, SES announced Monday it will buy at least seven high-capacity broadband and data relay satellites from Boeing for launch in 2021 into a rarely-used orbit several thousand miles over the equator.

Building on a model SES says has been successfully demonstrated by O3b, which has launched 12 satellites and has eight more under construction, the "O3b mPower" program will beam broadband connectivity into many more parts of the world, meeting the entire data traffic needs of some small countries, officials said in a press conference Monday at Euroconsult's annual World Satellite Business Week meeting in Paris.

The new satellites will have more power than O3b's current constellation, and SES sel ected Boeing — not Thales Alenia Space, the builder of O3b's existing satellites — as prime contractor for O3b mPower's space segment.

"O3b mPower will be the first multi-terabit satellite constellation," said Steve Collar, CEO of SES Networks and former head of O3b. "It will have global capability and it delivers what we're calling virtual fiber. It's the only system that's capable of delivering a total network over satellite without having to use any kind of terrestrial connectivity at all. There's no system that can do that on the level of scale, performance and economics that make sense."

The announcement was short on technical details, and SES and Boeing officials declined to answer questions on the mass and power level of each spacecraft.

The satellites will launch into a unique equatorial orbit, the same type of "medium Earth orbit" currently populated by O3b's network, which flies around 5,000 miles (8,000 kilometers) over the equator, making five orbits of the planet each day.

Officials did not disclose the altitude of the planned O3b mPower fleet, but the seven satellites announced Monday will be parked in orbits directly over the equator.

SES could add more satellites to the O3b mPower network at higher inclinations.

"The unique thing about this is we don't have to launch all of that at once," Collar said. "We don't need to spend billions and billions and billions in putting the system up. We can scale this system over time, which is something that's incredibly unique to O3b mPower."

Karim Michel Sabbagh, president and CEO of Luxembourg-based SES, said the company is not investing any more money in O3b mPower than was already planned in its capital expenditure forecasts. Sabbagh declined to put a financial value on the O3b mPower investment, but he said SES will cancel plans to replace two of its aging large geostationary communications satellites, a move that will offset the cost of O3b mPower.

Like the current O3b fleet, the new satellites will beam low-latency broadband signals to terminals on the ground. But O3b's satellites each host 10 broadband beams, while each O3b mPower will have 4,000 beams.

"We can dynamically route traffic," Collar said. "We can form beams and reform them on a dynamic basis across a day, a month or a year. We can form tends of thousands of beams across this system and serve our customers whereever they are, but, importantly, we're not putting any power down on anywhere there isn't a customer."

In hindsight, the O3b mPower program was telegraphed by SES officials years ago as they discussed internal debates about whether to buy smaller, shorter-lived satellites that could be adapted to meet new user demands years after their launch.

SES first invested in O3b in 2009, then took 100 percent ownership of O3b in 2016. The O3b network was originally envisioned as a way to connect the estimated three billion people — the "other 3 billion" — without Internet access.

"This takes the idea of O3b and dramatically scales it to tens of thousands of end points, to communities whether they be villages, towns or cities, whether it's every aircraft that's flying in the world, every cruise ship, every vessel, every government requirement can be addressed ultimately within the O3b mPower ecosystem," Collar said.

The ground terminals will have internal computers and data storage capacity, allowing them to switch between the O3b mPower network, broadband from SES's geostationary satellites and ground-based connections, enabling near-global coverage.

"This is a step change in terms of SES's capability, but I actually think it's a step change in terms of the way that satellites respond to future demand," Collar said.

O3b's satellites in equatorial orbit can reach customers between 45 degrees north and south latitude.
O3b Networks is now beaming Internet connectivity to service providers and telecom operators in Africa and the Pacific islands, reaching customers in South Sudan, Madagascar, East Timor, Samoa, Nauru and Papua New Guinea, among other countries.

Collar said O3b is delivering more bandwidth to Royal Caribbean's cruise ships than the rest of the maritime industry combined, and beaming 50 percent of the bandwidth used in Kinshasa, capital of the Democratic Republic of Congo.

SES says O3b, and O3b mPower in the future, will offer fiber-quality network connections without the need to lay cable in remote, rugged terrain.

"We have unlocked a market we didn't think we could unlock with the current O3b system," Sabbagh said. "Having said that, we always knew from the beginning that the current system is confined to 200 beams, so nominally to 200 clients ... If you want to think about it in terms of a comparison, it's 10 beams vs. 4,000 beams per spacecraft. It gives you an idea of our ability to democratize the delivery of the service and to be able to enable all those market segments.

"In a sense, we're starting to do that today, but we're doing it with a finite part of the target market, and we want go all the way," Sabbagh said. "The market we see today will continue to expand."

"If we wanted to deliver all the capability that Papua New Guinea would require from now thorugh the next 15 years, without having to use meaningful terrestrial infrastructure, (we could with O3b mPower), which persuades me that we've got exactly the right idea," Collar said. "We can deliver the international and domestic traffic for a country on this system — not every country in the world — but if we can benchmark the system against that capability, then we've got something that's genuinely unique."

SES has not sel ected a launcher for the O3b mPower satellites. Depending on the launch site and the rocket, three or four O3b mPower spacecraft could fly on the same booster.

O3b's 12 spacecraft already in orbit launched in groups of four from French Guiana on Europeanized Soyuz rockets marketed by Arianespace. Two more O3b launches — each with four satellites — are reserved on Arianespace Soyuz rockets for flights in 2018 and 2019.

Collar said the O3b mPower satellites are not restricted to launching from French Guiana, a spaceport located in South America around 5 degrees north latitude. Each spacecraft will have efficient electric propulsion thrusters, giving them the ability to maneuver over the equator even if launched fr om higher latitude sites like Cape Canaveral, Collar said.

"We do not have to focus on a single launcher," Sabbagh said.

Paul Rusnock, chairman and CEO of Boeing Satellite Systems, said the O3b mPower platforms will carry newly-designed phased array antennas not yet flown in space. The satellites are based on a new design, with electronics and avionics fr om Boeing's 702 geostationary spacecraft bus.

ЦитироватьSES заказала ещё 2 запуска Falcon 9
Компания подписала контракт на запуск спутников среднеорбитальной группировки «O3b mPower» на Falcon 9, начало развёртывания которой запланировано на конец 2021 года.
На данный момент зарегистрированная в Люксембурге компания является обладателем одной из самых больших коммерческих группировок геостационарных спутников связи, предоставляя услуги для кораблей, самолётов, развивающихся и островных государств, а также других заказчиков.
На среднеорбитальную группировку «O3b» сейчас приходится 20 спутников, произведённых французской фирмой Thales Alenia Space. А в общей сложности SES S.A. принадлежит около 70 спутников связи.
В 2017 году для обновления группировки O3b у Boeing было заказано 7 спутников нового поколения с передатчиками Ka-диапазона. А в прошлом году для их вывода также было заказано 2 запуска Falcon 9. В августе было сообщено об заказе производства ещё 4 спутников, а в четверг SES также сообщила о заказе новых запусков у SpaceX. Таким образом 11 спутников нового поколения должны быть выведены в 4 запусках Falcon 9.
Каждый из этих спутников будет базироваться на платформе Boeing 702X и весить около 2 тонн, обеспечивая связь для более чем 4 тыс. пользователей – в 10 раз больше, чем прошлое поколение спутников. При этом каждому из клиентов будет предоставляться канал от 50 Мбит/с до нескольких Гбит/с, а суммарная пропускная способность 7 спутников должна достичь 10 терабит в секунду!

«O3b mPower – это краеугольный камень нашей многоорбитальной «облачной» высокопроизводительной сети, которая будет служить нашим коммерческим, мобильным и государственным заказчикам в новом десятилетии. И мы находимся всего в годе от её первого запуска – сказал директор SES Стив Коллар (Steve Collar). «У нас есть прочное и давнее партнёрство со SpaceX и мы рады добавить запуски O3b mPower, которые обеспечат большую эффективность и существенно большую пропускную способность нашей ведущей в отрасли сети».
SES сотрудничает со SpaceX ещё начиная с 2013 года, когда те запустили их первый спутник на геопереходную орбиту. Они также стали первыми, чей спутник отправился в космос на повторно используемой 1-й ступени. Всего же по заказам SES на данный момент было осуществлено 6 запусков, а ещё 5 – запланированы на будущее.
«Поскольку SES расширяет созвездие O3b mPower с 7 до 11 спутников, Boeing и SES договорились о сотрудничестве в разработке коммерческих предложений услуг и возможностей для правительства США», – сообщил Стив Коллар в заявлении 7 августа. «Мы построили нашу сеть многоорбитальной, многочастотной, высокопропускной, гибкой и открытой архитектуры, всё более ценной для государственных пользователей».
Необходимо отметить, что 20 спутников O3b прошлого поколения были выведены на 5 ракетах-носителях «Союз» из французской Гвианы, в период с 2013 по 2019 года.
