MUOS [Lockheed Martin]
MUOS (Mobile User Objective System) is a next-generation narrowband tactical satellite communications system designed to significantly improve ground communications for U.S. forces on the move.
The new communications system, slated to become operational in 2010, would provide 10 times more throughput, or volume of information that can be transmitted, than the current UFO System, and will provide the US troops a much more reliable way to communicate, as it is not affected by weather, environmental constraints or foliage.
Under the new system, even troops in the most remote locations or buildings with no satellite access would see a big increase in communications capabilities, industry sources said.
In September 2004 the Lockheed team was selected against the Raytheon team.
Lockheed Martin Space Systems, Sunnyvale, Calif. the MUOS prime contractor and system integrator, was recently awarded a $2.1 billion contract to build the first two satellites and associated ground control elements by the U.S. Navy Space and Naval Warfare Systems Command (SPAWAR), on behalf of the Program Executive Office – Space Systems, San Diego, Calif. The contract also provides for options on three additional spacecraft. With all options exercised, the contract for up to five satellites has a total potential value of $3.26 billion.
MUOS satellites will be developed at the company's Commercial Space Systems unit in Newtown, Pa.; final assembly and test will occur in Sunnyvale. Lockheed Martin's award-winning A2100 bus, which has achieved over 100 years of on-orbit service, will serve as the MUOS spacecraft platform.
General Dynamics C4 Systems, Scottsdale, Ariz., which will lead the user-entry and integrated ground segments of the MUOS program, supplying a secure ground network, satellite control and network management, and a JTRS-compliant terminal solution.
Boeing Satellite Systems (BSS), El Segundo, Calif.; The satellite-manufacturing arm of Boeing Integrated Defense Systems will provide the legacy UHF payload.
Ericsson, Plano, Texas. The leader in 2G and 3G mobile technology systems will provide portions of the integrated ground segment.
Harris Corporation, Melbourne, Fla. A world leader in spaceborne, unfurlable mesh reflectors, Harris will provide the large reflectors for the MUOS program. The reflectors, two per satellite, will be manufactured at Harris facilities as part of the MUOS geo-synchronous satellite's ultra high-frequency (UHF)-band antenna system.
The planned launch of the first MUOS satellite was delayed to 2012 after a part of the budget was used to fund operations in Iraq.
The program is valued at $6.4 billion over its lifespan, which could run through 2024.

ЦитироватьSUNNYVALE, Calif., April 9, 2013 – Lockheed Martin [NYSE: LMT] has integrated two of the most important components onto its fourth Mobile User Objective System (MUOS (http://www.lockheedmartin.com/us/products/mobile-user-objective-system--muos-.html)) satellite for the U.S. Navy. Recently engineers mated the multi-beam assembly, which hosts 16 ultra-high frequency (UHF) antennas for distributed, global communications coverage. Earlier this year, the team delivered and integrated the vehicle's communications system module. With bus and payload now together, the satellite is entering its first system check-outs before progressing to environmental test.
Supporting UHF satellite communications, MUOS will provide mobile warfighters with assured communications, including the new capability of simultaneous voice, video and data for mobile users.
"MUOS-4 is gleaning the benefits of the lessons learned fr om the first three vehicles," said Iris Bombelyn, vice president of Lockheed Martin's Narrowband Communications mission area. "We continue to focus on reducing risk, maintaining efficient operations and delivering a flawless vehicle to our customer. Our execution on the ground is complemented by our performance on orbit, wh ere our first satellite is already in position and performing exceptionally."
Designed and built by Lockheed Martin in Newtown, Pa., and delivered to the company's facilities in Sunnyvale, Calif., the antenna and system module enable communications coverage using the wideband code division multiple access standard. This provides a 16-fold increase over legacy UHF communications in the number and capacity of satellite links.
The first MUOS satellite and associated ground system already provide legacy UHF communications capability. The second MUOS satellite recently completed (http://www.lockheedmartin.com/us/news/press-releases/2013/january/lockheed-martin-completes-work-on-u-s--navys-second-.html) system testing and is undergoing final preparations for shipping, then launch in July. The third spacecraft is progressing through environmental testing. The five-satellite, global constellation is planned to achieve full operational capability in 2016.
Lockheed Martin is under contract to deliver four MUOS satellites plus a spare and the associated ground system to the U.S. Navy. Lockheed Martin Space Systems (http://www.lockheedmartin.com/ssc/) in Sunnyvale is the MUOS prime contractor and system integrator. The Navy's Program Executive Office for Space Systems (http://www.public.navy.mil/spawar/PEOSpaceSystems/Pages/default.aspx), Chantilly, Va., and its Communications Satellite Program Office, San Diego, Calif., are responsible for the MUOS program.

The most powerful version of the United Launch Alliance Atlas 5 rocket has been assembled at Cape Canaveral to deploy the second satellite in the Navy's new mobile communications system.

Спойлер
The massive rocket, equipped with five strap-on solid-fuel boosters, will lift the 15,000-pound Mobile User Objective System satellite into orbit July 19 during a morning window of 8:51 to 9:35 a.m. EDT (1251-1335 GMT). It will be the year's fifth Atlas, the third for the Pentagon and the first using the expansive five-meter-diameter nose cone and solid motors.
This rocket is known as the 551 configuration of the multi-varient Atlas 5 family, which is tailored with different sized nose cones and strap-on solids to match the cargo's mass, size and targeted destination.
ULA provided this cutaway illustration (http://www.ulalaunch.com/site/docs/products/Cutaways/Atlas500_Cutaway.pdf) that shows the elements of the rocket.
Previous uses of the high-energy configuration have hurled NASA probes on paths to Pluto in 2006 and Jupiter in 2011 and successfully heaved the first MUOS satellite to space last year.
ULA technicians began stacking this latest rocket at the Vertical Integration Facility with erection of the first stage on May 29. Its RD-180 main engine will burn a highly refined kerosene fuel and liquid oxygen.
Known as the Common Core Booster, the 106.6-foot-long stage was rotated vertical, then maneuvered into the building and stood upright on the mobile platform that rolls to the pad for launch.
The next several days were spent installing the five solid rocket boosters to the attachment fixtures on the first stage. Built by Aerojet, the motors ignite at liftoff to deliver a power boost in thrust.
In the case of MUOS, the solids enable the Atlas to carry a much heavier payload than is otherwise possible.
Once the interstage hardware was set in place, workers on Tuesday hoisted the 41.5-foot-long Centaur upper stage atop the first stage. It will be enclosed within the rocket's large nose cone for the initial minutes of ascent through the atmosphere.

Спойлер
Centaur's single RL10 engine, fueled by liquid hydrogen and liquid oxygen, will perform three burns to reach the desired geosynchronous transfer orbit for deployment of MUOS 2. The spacecraft is undergoing processing at its own cleanroom facility for final testing, fueling and encapsulation in the rocket's nose cone.
After the Atlas goes to the pad at the end of this month for a countdown dress rehearsal, it will be brought back to the assembly building to be fitted with the MUOS 2 satellite in early July.
Built by Lockheed Martin, the MUOS 2 spacecraft will continue the orbital construction of the Navy's planned five-satellite fleet to provide cellphone-like communications.
MUOS will offer 10 times greater communications capacity to the mobile warfighter over the Navy's current generation of Ultra High Frequency Follow-On spacecraft to relay narrowband tactical information such as voice calls, data messaging, file transfers and email.
The sophisticated MUOS system was designed around the commercial third-generation cellular telephone architecture to substantially increase the number of users and amount of communications that can be routed to military forces.
"MUOS 2 will add on-orbit military satellite communication that is heavily in demand. Our first space vehicle has performed exceptionally on orbit, providing legacy payload voice calls at full capacity. In fact, we recently demonstrated mobile data and voice transmissions using our advanced payload," said Iris Bombelyn, vice president of Narrowband Communications at Lockheed Martin.
The upcoming launch will be ULA's 72nd since its formation in December 2006

Liftoff is scheduled for July 19 during a morning window of 8:51 to 9:35 a.m. EDT (1251-1335 GMT) fr om Complex 41. At nearly 15,000 pounds, the Mobile User Objective System satellite is a hefty cargo requiring the most powerful version of the Atlas 5 to carry the payload into a highly elliptical geosynchronous transfer orbit.
The 551 configuration of the Atlas features five strap-on solid-fuel boosters and the five-meter-diameter nose cone. Previous flights have included hurling NASA's New Horizons probe to Pluto and Juno to Jupiter.
ULA created this cutaway illustration (http://www.ulalaunch.com/site/docs/products/Cutaways/Atlas500_Cutaway.pdf) that shows the elements of the rocket.
It will be the fifth Atlas 5 of the year, the 39th in the past decade and the second for the MUOS series following the successful first deployment in February 2012.
The Atlas 5 and its Centaur upper stage will deliver the MUOS 2 spacecraft into a preliminary orbit about three hours after liftoff, allowing the Lockheed Martin-built satellite to begin its independent series of maneuverings to achieve a geosynchronous orbit 22,300 miles above Earth.
MUOS is a next-generation space communications system that utilizes commercial 3G cell phone technology to provide voice, data and video services to military troops on the move.
Each MUOS satellite is likened to a cell tower in the sky to serve ships, submarines, aircraft, land vehicles and terminals in the hands of troops. The design enables increases in the number of users and amount of communications that can be routed to military forces in contrast to current satellites.
When completed by 2017, the MUOS constellation will feature four primary birds and one spare in orbit to ring the planet and provide capacity, availability and global coverage for mobile military communications like never before.

MUOS 2 arrived in Florida on May 13 after being flown on an Air Force C-5 transport aircraft from Lockheed Martin's satellite factory in Sunnyvale, Calif. Unloading at the Shuttle Landing Facility, the craft was taken to the commercial Astrotech satellite processing campus in nearby Titusville for final testing, the loading of propellants and encapsulation within the rocket's payload fairing.
Crews early Monday moved the satellite across Kennedy Space Center and down to the Vertical Integration Facility wh ere the Atlas awaited the arrival of its cargo. MUOS was hoisted atop the rocket to begin the connection process and complete the assembly of the 206-foot-tall launcher.
A tip-to-tail electrical check, called the combined systems test, will be run this week to verify all is in readiness for flight.
Rollout of the Atlas 5 aboard its mobile platform to the launch pad is planned for July 17. The launch team will initiate the seven-hour countdown in the early morning hours of July 19.

In today's first weather briefing to mission managers, all current conditions are observed GO for launch of the Atlas 5 rocket and odds for the 8:48 a.m. EDT liftoff time stand at 40 percent favorable. The main concern that meteorologists are watching is the thickness of clouds that the rocket would fly through and a slight concern about electrically-charged anvil clouds drifting over the Cape.
The outlook for the launch window now predicts scattered clouds at 2,500 feet, broken clouds at 15,000 feet and overcast conditions at 25,000 feet, good visibility, southerly winds of 10 gusting to 14 knots, a temperature of 78 degrees F and humidity level of 95 percent.
If the launch should slip to Saturday for some reason, there is a 70 percent chance of acceptable wether.
0635 GMT (2:35 a.m. EDT)
The Atlas-Centaur rocket has been powered up at Complex 41 and guidance system testing is getting started for today's launch, as the countdown progresses as planned.
0548 GMT (1:48 a.m. EDT)
The countdown begins now for this morning's launch of the Atlas 5 rocket to deploy the Navy's MUOS 2 communications satellite for mobile military users.
Clocks are picking up the seven-hour sequence of work that will prepare the booser, payload and ground systems for blastoff at 8:48 a.m. EDT (1248 GMT).
Soon the launch team will begin powering up the rocket to commence standard pre-flight tests. Over the subsequent few hours, final preps for the Centaur's liquid oxygen and liquid hydrogen systems will be performed, along with a test of the rocket's guidance system and the first stage propulsion and hydraulic preps, internal battery checks and testing of the C-band system used to track the rocket as it flies downrange, plus a test of the S-band telemetry relay system. The Complex 41 site will be cleared of all personnel at 5:53 a.m.
A planned half-hour hold begins at 6:08 a.m. when the count reaches T-minus 120 minutes. Near the end of the hold, the team will be polled at 6:35 a.m. to verify all is in readiness to start fueling the rocket for launch.
Supercold liquid oxygen begins flowing into the Centaur upper stage around 6:55 a.m., followed by the first stage filling around 7:08 a.m. Liquid hydrogen fuel loading for Centaur will be completed a short time later.
A final hold is scheduled at the T-minus 4 minute mark starting at 8:34 a.m. That 10-minute pause will give everyone a chance to finish any late work and assess the status of the rocket, payload, Range and weather before proceeding into the last moments of the countdown.
The launch window extends from 8:48 to 9:32 a.m. EDT (1248-1332 GMT).

Уже как 10 минут, как спутник должен был отделиться... Ждем.
Говорят, есть отделение.
MISSION SUCCESS! The @ulalaunch Atlas 5 completed its third burn of upper stage and deployed #MUOS2 for the US Navy.
Остается открытым вопрос, в какую точку он будет установлен на ГСО?
Согласно этой картинке: http://novosti-kosmonavtiki.ru/forum/messages/forum12/topic13502/message1095436/#message1095436
где-то ближе к Австралии. Но это не совсем стыкуется с планируемыми ранее координатами 75E.
Кажется, понял. Над Австралией он отделяется и далее "поползет" к точке 75E. Так?

Ой горе-горюшко. Разве это не стандартное выведение на ГПО/ГСО с Канаверала?

ЦитироватьС мыса Канаверал в США запущен тактический спутник связи Пентагона нового поколения
22.07.2013 АРМС-ТАСС
НЬЮ-ЙОРК, 19 июля. (АРМС-ТАСС). С мыса Канаверал сегодня в 09:00 по времени Восточного побережья США (17:00 мск) был осуществлен запуск тактического спутника связи нового поколения. Космический аппарат станет частью орбитальной группировки MUOS (Mobile User Objective System), принадлежащей Пентагону.
Запуск спутника провела компания "Юнайтед лонч эллайенс" (United Launch Alliance) - совместное предприятие авиационных гигантов "Боинг" и "Локхид Мартин". Космический аппарат был заточен в специальную капсулу в верхней части ракеты-носителя "Атлас-5", в первой ступени которой используется российский ракетный двигатель РД-180 НПО "Энергомаш".
Система MUOS находится в ведении военно-морских сил США и разработана компанией "Локхид Мартин". Она призвана значительно улучшить связь между войсками США и их союзниками по всему земному шару. MUOS, эффективно сочетающая в себе самые современные технологии связи третьего поколения, предлагает в 10 раз более быструю связь по сравнению с имеющимися спутниковыми системами, в том числе, при одновременном голосовом подключении, передаче изображения и данных. Кроме того, спутниковый комплекс совместим с уже имеющимися в распоряжении войск терминалами связи.
Первый спутник связи данной системы был запущен 24 февраля 2012 года. Всего "Локхид Мартин" планирует построить для Пентагона пять таких аппаратов, в том числе, один - резервный.

Согласен, мне тоже понравилось фото. Наверно с удаления 80-100 км заснято, с севера-северо-запада. А объект должен был уйти на юго-восток, как я понимаю.

Прошу меня простить за дилетантизм в вопросе вывода полезной нагрузки на ГСО.
Меня в первкю очередь интересует то, что MUOS2 будет передавать. С этой целью и интересуюсь его будущим местоположением на орбите. Если будет возможность, направьте в правильное место, где быстрее появятся TLE или просто позиция.

Забавная, конечно, шутка. Флитсаткомовских позиций немало по всему земному шару :)

Вот это было бы неплохо. Тогда он будет у нас в зоне видимости и можно будет послушать.
Спасибо!

А, ну это другой разговор. Раз адекватный дилетант который согласен, что он- дилетант - то помогу, чем смогу. Эта картинка не говорит, куда поставят спутник.

Американские военные данные. Наследник флитсаткомов?

Это вам надо заглянуть на сисат или скачать ТЛЕ от независимых наблюдателей. Если они не увидят сабж- то придётся ждать Европейского классификатора, там он точно будет.

Это не шутка. Я не знаю, где именно, он может встать. Но я знаю, где его стоит искать. ;)

В любом случае, там есть обычные транспондеры UHF диапазона, стандартные для UFO, Fleetsatcom, Skynet, Sicral. По крайней мере, про "Legacy" написано, что поддерживается.

Ok. Жду. Пока нет данных.

Через 90 градусов выглядит логичным, ибо активных намечено 4 штуки и еще один запасной.
Естественно, никто их не поставит ровно через 90 градусов.
Но то, что MUOS1 поставили над штатами, дает высокую вероятность, что следующий будет уже в нашей видимости.

New Navy satellite spreads wings, antennas in orbit
BY JUSTIN RAY
SPACEFLIGHT NOW
Posted: August 2, 2013
The massive U.S. Navy communications satellite launched from Cape Canaveral two weeks ago has completed prescribed maneuvers to reach geosynchronous orbit and successfully unfurled its umbrella-like antenna reflectors.
Checkouts of the spacecraft that are expected to last several months are getting underway high above the Pacific Ocean testing location before the bird will be declared ready for service.
The craft will be capable of covering nearly a third of the planet to provide mobile communications to U.S. warfighters on the move.
"Currently, all systems are working normally," said Steven A. Davis of the Space and Naval Warfare Systems Command.
The Mobile User Objective System satellite No. 2 was lofted into space July 19 by the United Launch Alliance Atlas 5 rocket, achieving a highly elliptical preliminary orbit as planned.
From there, the Lockheed Martin-built satellite performed a series of 7 engine firings to circularize the orbit and reduce its orbital tilt closer to the equator. The burns, which ranged from 23 to 52 minutes in length, put the spacecraft into the proper geosynchronous orbit 22,300 miles up.
The orbit was reached on July 31, and the following 36 hours saw the spacecraft achieve its "flight configuration" by executing critical deployments of the power-generating solar wings that now stretch 94 feet tip-to-tip and two gold mesh, umbrella-like antenna reflectors.
The antennas provide the same type of Ulta High Frequency communications like previous Navy spacecraft and the other offers modernized capabilities that the new MUOS system will create.
Coverage to legacy users will transmit through a 17.7-foot-diameter reflector on the bottom of the craft and the advanced, multi-beam features of MUOS to significantly increase the transmission capacity over the Navy's previous satellites will use a large 46-foot reflector atop MUOS.
All U.S. military forces rely upon Navy satellites for Ultra High Frequency narrowband communications. UHF offers small, portable units that forces can carry into battle and the frequency enables communications in urban canyons and mountainous terrain, penetrating foliage and transmitting through bad weather.
Each MUOS satellite has 16 times the capacity of the aging UHF satellite constellation.
What's more, MUOS also creates a new "rugged smartphone" network to provide 3G-like cellular telephone and data services across the globe when the constellation is fully launched in the next couple of years.
Now begins several months of satellite system and payload testing before builder Lockheed Martin hands over the MUOS 2 craft to the government for additional checks in advance of setting it operational in early 2014.

Так как там с точками стояния первых двух аппаратов? Чё-то не нашел ваще...
Первый на начало года стоял в 177 запада (см. европейский классификатор). По второму в открытых источниках данных нет.

Стоп. А куда его могли поставить вне зоны видимости сообщества? Рядом их ставить нет резона ( имхо). так как никакой объективной причины для огромных потоков данных сейчас в том регионе нет.
Че-то проскакивало, что второй встанет над Гавайами, т.е. в 177. Тогда первый переведут куда-нибудь наверно.
Вообще, это напоминает "Неуловимого Джо", которого никто не ловит))

Да, ситуация весьма интересная. Неужели на Гавайях нет никого, кто мог бы:
1. Снять небо
2. Написать на сисат?
Неужели в России нет никого, кто мог бы:
1. Найти подходящую all-sky камеру.
2. Вырезать нужную область вблизи равноденствия.
3. Померять и написать на сисат?
:)
Неделю назад на UFO2 были выключены 3 транспондера в нижней части UHF диапазона.
Остальные работают как и раньше.
Возможно, расчищают диапазон для нового аппарата.
ЦитироватьIn a presentation here, Justin Keller, director of advanced programs in Lockheed Martin's military space systems office, said a C-130 transport aircraft fitted with an omnidirectional blade antenna maintained calls via MUOS while flying to 89.5 degrees north. The same performance could be expected in the Antarctic, he said.
Keller said MUOS's design specifications call for the system to be able to maintain stable 24/7 call connectivity up to 65 degrees north latitude. But MUOS's key advantage over the legacy UHF satellite communications systems that it is succeeding is its Wideband Code Division Multiple Access (WCDMA) payload.
The 16 WCDMA beams are designed to offer much faster tactical communications links, up to 384 kilobits per second.
Keller said the C-130 was flying at a speed of 300 knots at an altitude of 7 kilometers. An equivalent link between MUOS and a user standing at sea level would have been 83 degrees north, he said. He cautioned that stable communications at this latitude would not be assured on a 24/7 basis, but that the demonstration showed that some operations were possible much farther north than expected.
Global warming has made the Northwest Passage much more popular as a commercial sea route, and the widening ice-free areas make the region much more valuable, and potentially contested, for its energy and mineral deposits.
Russia, Canada and Norway are all planning space systems to survey the Arctic region.
In addition to its 16-beam WCDMA capacity, delivered through a 14-meter-diameter unfurlable mesh antenna built by Harris Corp. of Melbourne, Fla., MUOS carries a legacy UHF payload designed to work with UHF radios already on the market and used by several allied nations to assure communications links for their troops.
Keller said the same flights that established the links with the MUOS WCDMA payload could not complete calls using the legacy UHF payload on MUOS despite efforts using this payload's 5- and 25-kilohertz channels.
Several allied nations have purchased F-35 Joint Strike Fighter aircraft that, in principle, are designed with communications links to MUOS's WCDMA payload. But the nations making these purchases are not receiving the communications pods with WCDMA because that payload is reserved for U.S. use only.
At least for now. Harold Haney, chief of space and missile defense in the Command, Control, Communications and Computers Division of the U.S. Strategic Command in Omaha, Neb., said the idea of opening all of MUOS's capability to allies is a regular subject of debate.
"This could change. But until there are some political requirements for cooperation [with allies] on MUOS, we cannot change the policy," Haney told the conference. "The F-35s that were sold to a number of nations were not sold with the MUOS boxes in it. The buyers will decide on the comms options themselves."
