Maintaining Arianespace's flight tempo: the first Ariane 5 for launch in 2017 is at the Spaceport
(https://img.novosti-kosmonavtiki.ru/223085.jpg)
The protective container with Ariane 5's EPC cryogenic main stage is unloaded fr om the MN Colibri roll-on/roll-off transport ship.
Preparations are starting for another busy year of Arianespace launch activity, with the initial Ariane 5 of 2017 now delivered to the Spaceport in French Guiana.
This vehicle recently arrived in French Guiana aboard the MN Colibri, which is one of two roll-on/roll-off ships that transport Arianespace launchers from their European manufacturers to South America.
After docking at Pariacabo Port, the Ariane 5's components were unloaded and transported by road to the Spaceport – wh ere they will be assembled during activity inside the Launcher Integration Building.
Getting off to a strong start in 2017
The first Ariane 5 mission of 2017 – designated VA235 – will orbit a pair of communications satellites: SKY Brasil-1, for operation by DirecTV Latin America; and Indonesian service provider PT Telkom's Telkom-3S.
A total of 232 Ariane missions have been performed since the family of European launch vehicles began operation in 1979. Number 233 will be marked on Arianespace's next flight from the Spaceport, scheduled for November 17 – during which an Ariane 5 ES version will loft four satellites for Europe's Galileo navigation system.
So far in 2016, Arianespace has conducted five flights with the heavy-lift Ariane 5. This activity was complemented by two missions using the medium-lift Soyuz, plus one with the lightweight Vega vehicle.
Arianespace's 2016 launch activity will be completed with two December missions: the Vega flight with Turkey's GÖKTÜRK-1A observation satellite, which will be followed by an Ariane 5 mission to orbit the JCSAT-15 and Star One D1 telecommunications relay platforms.

Satellites are fueled and ready to go for Arianespace's first Ariane 5 mission of 2017
The two telecommunications satellites for Arianespace's next heavy-lift Ariane 5 launch – SKY Brasil-1 and Telkom 3S – have been fueled in preparation for liftoff next week fr om the Spaceport in French Guiana.
(https://img.novosti-kosmonavtiki.ru/222950.jpg)
Sky Brasil-1 (left) and Telkom 3S (at right) are fueled in the Spaceport's S5 payload processing facility, clearing the way for their integration on Ariane 5.
This flight will be the initial Ariane 5 mission in 2017 and the second of up to 12 Arianespace launches during the year operated with the company's launcher family, which also includes the medium-lift Soyuz and lightweight Vega.
Ariane 5's overall payload lift performance for the upcoming flight – set for February 14 from the Spaceport's ELA-3 launch zone – is more than 10.4 metric tons. Its two passengers will be deployed into geostationary transfer orbit during a profile lasting just under 40 minutes.
The mission is designated Flight VA235 in Arianespace's numbering system, signifying the 235th launch of an Ariane family vehicle from the Spaceport since the series of European-built launchers entered service in December 1979.
Payload fairing logos for the mission's two passengers
Ahead of the satellites' integration on Ariane 5, the ogive-shaped payload fairing that will protect them during initial climb-out through the atmosphere has been adorned with decals representing the two satellites' operators and the spacecraft manufacturers.
Affixed on the fairing's upper position are logos for the SKY Brasil-1 satellite, to be utilized by AT&T/DIRECTV via its DIRECTV Latin America subsidiary to expand direct-to-home high definition programming. The spacecraft will be separated first during the Flight VA235 sequence, and is to provide coverage over Brazil once operational from its geostationary orbital slot.
SKY Brasil-1 was built by Airbus Defence and Space in Toulouse, France, using the Eurostar E3000 platform.
Flight VA235's Telkom 3S passenger will be integrated in Ariane 5's lower payload position for release during the mission's second deployment phase. This satellite will provide high-definition television services, as well as mobile communications and internet applications for Telkom Indonesia. It was built by Thales Alenia Space in Toulouse and Cannes, France using a Spacebus 4000B2 platform.
Up to seven Ariane 5 liftoffs planned during 2017
The Ariane 5 for next week's launch currently is in the Spaceport's Final Integration Building, wh ere it is ready for installation of the two satellite passengers. It was delivered to Arianespace by Airbus Safran Launchers, production prime contractor for the heavy-lift vehicle.
Arianespace's busy mission manifest for 2017 – to be confirmed based on payload availability – foresees up to seven Ariane 5 launches during the year, joined by three missions utilizing Vega and two with Soyuz.
The year's activity began on January 27, when a Soyuz lofted Europe's Hispasat 36W-1 telecommunications satellite on the medium-lift launcher's first mission from French Guiana to geostationary transfer orbit.

Released first during Flight VA235 will be SKY Brasil-1, developed for utilization by AT&T/DIRECTV via its DIRECTV Latin America subsidiary to expand direct-to-home high definition programming. The 6,000-kg.-class satellite was produced by Airbus Defence and Space in Toulouse, France, using the spacecraft manufacturer's Eurostar E3000 platform.
Approximately 12 minutes after SKY Brasil-1's separation will be the deployment of Telkom 3S, designed for the delivery of high-definition television services as well as mobile communications and internet applications for Telkom Indonesia. The 3,550-kg. relay platform was built by Thales Alenia Space – Toulouse and Cannes, France, based on the Spacebus 4000B2 platform.
A busy year for Arianespace's launcher family
Flight VA235 is one of up to 12 Spaceport missions to be operated during the year by Arianespace's launcher family, which also is composed of the medium-lift Soyuz and lightweight Vega. Of the total, as many as seven liftoffs in 2017 will utilize Ariane 5s – developed and built by Airbus Safran Launchers as production prime contractor.
The next mission after Flight VA235 is scheduled for early March with Vega, deploying the Sentinel-2B Earth observation satellite into a Sun-synchronous orbit.
Arianespace opened its 2017 launch activity on January 27, when a Soyuz vehicle orbited Hispasat 36W-1 on a trajectory that injected the telecommunications satellite into geostationary transfer orbit.

Ariane 5 Launch:
This is the first Ariane 5 launch of the year, following on for seven successful launches of the rocket during 2016.
Arianespace has already seen in the new year, with the launch of its Soyuz ST-B rocket, which successfully lofted the Hispasat 36W-1 at the end of January (https://www.nasaspaceflight.com/2017/01/arianespace-soyuz-st-b-launches-hispasat-36w-1/).
Tuesday's launch is designated Flight VA235 in Arianespace's launcher family numbering system. It is one of up to 12 missions in total that are planned this year with Arianespace's heavy-lift Ariane 5, medium-lift Soyuz and lightweight Vega.
(https://img.novosti-kosmonavtiki.ru/208972.webp)
Arianespace will soon have the Ariane 6 added to its rocket team (https://www.nasaspaceflight.com/?s=Ariane+6), with more baseline information recently released via the publication of the user manual (http://www.arianespace.com/wp-content/uploads/2017/02/Ariane6_Users-Manual_February2017.pdf).
The document pays tribute to the Ariane family, which began with the Ariane 1 rocket which conducted its maiden launch in 1979.
"With the Ariane family, Arianespace experience is as of beginning 2016, of more than 380 launch contracts, 227 flights, 350 satellites launched (thanks to the shared launch capability), 53 auxiliary payloads launched, over a period of 36 years."
For this latest mission, Ariane 5's overall payload lift performance for the upcoming flight is more than 10.4 metric tons. Its two passengers will be deployed into geostationary transfer orbit during a profile lasting just under 40 minutes.
Released first during Flight VA235 will be SKY Brasil-1, with Telkom 3S following 12 minutes later.
(https://img.novosti-kosmonavtiki.ru/208973.jpg)
Due to this deployment schedule, SKY Brasil-1 is located in the launcher's upper payload position.
Developed for utilization by AT&T/DIRECTV via its DIRECTV Latin America subsidiary, the 6,000-kg.-class satellite is to expand direct-to-home high-definition programming for Brazil. It was produced by Airbus Defence and Space in Toulouse, France, using the spacecraft manufacturer's Eurostar E3000 platform.
SKY Brasil-1 (also known as SKYB-1) will be the 10th satellite launched by Arianespace for the operator AT&T/DIRECTV. The most recent launch was on May 27, 2015, lofting SKY México-1 and DIRECTV 15 on the same Ariane 5.
"This will be one of two satellites that will support our SKY Brasil business providing us with the capacity to deliver superior products and services to our growing customer base in Brazil," noted Bruce Churchill, president of DIRECTV Latin America. "We're looking forward to another successful Arianespace launch."
It is the 116th spacecraft from this manufacturer and its predecessors to be launched by Arianespace, with the order book including 17 more Airbus Defence and Space satellites to be launched.
Riding in the lower payload slot, Telkom 3S will be deployed at just under 40 minutes after Ariane 5's liftoff. This 3,550-kg. relay platform was designed for the delivery of high-definition television services, as well as mobile communications and Internet applications for Telkom Indonesia – providing coverage over Indonesia and Southeast Asia.
It will be orbited in the framework of a turnkey contract with Thales Alenia Space, which produced it at Toulouse and Cannes, France, based on the Spacebus 4000B2 platform.
"It's very fulfilling to be able to support our customer's business development. The deployment of Telkom-3S will enhance PT Telkom's broadcast capacity and provide valuable services for enterprises, IP backbones and mobile network backhauling," added said Jean-Loïc Galle, President and CEO of Thales Alenia Space. "Telkom-3S (was) the 80th Spacebus satellite built by Thales Alenia Space."
(https://img.novosti-kosmonavtiki.ru/208974.jpg)
The spacecraft is outfitted with 24 C-band transponders, eight extended C-band transponders and 10 Ku-band transponders.
After Telkom 1 and Telkom 2 respectively launched in 1999 and 2005, Telkom 3S will be the third satellite entrusted to Arianespace by Telkom Indonesia, this time within the scope of a turnkey contract with Thales Alenia Space.
Telkom Indonesia is an Indonesian state-owned company that supplies telecommunications, information, media and entertainment services (TIMES) to millions of customers throughout the Indonesian archipelago.
Telkom 3S will provide high-definition television services (HDTV), as well as mobile communications and internet applications. Positioned at 118° East, Telkom 3S will provide C-band coverage of Indonesia and Southeast Asia, while extended C-band beams will cover Indonesia and part of Malaysia.
It also is fitted with Ku-band transponders dedicated to national coverage.
Telkom 3S is the 146th satellite built by Thales Alenia Space and its predecessors to be launched by Arianespace. The Arianespace order book includes nine more Thales Alenia Space satellites to be launched.

An Ariane 5 success for long-time partners maintains Arianespace's 2017 launch tempo (https://img.novosti-kosmonavtiki.ru/223094.jpg) The Ariane 5 for Flight VA235 is shown at the Spaceport's ELA-3 launch zone, ready for liftoff with its SKY Brasil-1 and Telkom 3S satellite passengers.
The first Ariane 5 mission in 2017 – and Arianespace's second launch this year – orbited two relay satellites from French Guiana today to continue the company's relationships with long-term telecommunications operators and satellite manufacturers.
Lifting off from the Spaceport's ELA-3 launch zone, the workhorse vehicle placed SKY Brasil-1 and Telkom 3S into geostationary transfer orbit (GTO) during a mission lasting just under 40 minutes.
"Tonight's Ariane 5 served two satellite operators with whom Arianespace enjoys strong relationships," said Stéphane Israël, the Chairman and CEO of Arianespace. "SKY Brasil-1 is the 10th satellite launched by Arianespace for AT&T/DirecTV, representing 50 percent of all AT&T/DirecTV satellites in operation today, while all of Telkom Indonesia satellites in operation today have been launched by Arianespace."

Impressive numbers with the satellite manufacturers (https://img.novosti-kosmonavtiki.ru/222943.jpg)
With an on-time departure from the Spaceport, Arianespace's Flight VA235 deployed SKY Brasil-1 and Telkom 3S into geostationary transfer orbit.
Israël noted that SKY Brasil-1 was the 116th satellite built by Airbus Defence and Space to be launched by Arianespace, with 17 more from the manufacturer in Arianespace's backlog.
Telkom 3S was manufactured by Thales Alenia Space, and it marked the 146th spacecraft produced by the company to be orbited by Arianespace, which has nine more in its backlog.
Ariane 5's total payload lift performance on today's mission – designated Flight VA235 in Arianespace's launcher family numbering system – was 10,482 kg. This total included the liftoff masses of approximately 6,000 kg. for SKY Brasil-1 and 3,550 kg. for Telkom 3S, plus the Ariane 5's SYLDA dual-passenger dispenser system and payload adapter hardware. The launcher was delivered to Arianespace by Airbus Safran Launchers as production prime contractor.
Ariane 5's deployment of SKY Brasil-1 and Telkom 3S
At 27 minutes into Flight VA235, Ariane 5 deployed SKY Brasil-1 from the launcher's upper payload position. Developed for utilization by AT&T/DIRECTV via its DIRECTV Latin America subsidiary, SKY Brasil-1 will expand direct-to-home high-definition programming for Brazil. The spacecraft was produced in Toulouse, France using Airbus Defence and Space's Eurostar E3000 platform, and will operate from an orbital slot of 43.1 deg. West.
Telkom 3S was in the Ariane 5's lower payload slot, and was orbited in the framework of a turnkey contract with Thales Alenia Space, which produced the satellite at Toulouse and Cannes, France, based on the Spacebus 4000B2 platform. Designed for the delivery of high-definition television services, as well as mobile communications and Internet applications for Telkom Indonesia, Telkom 3S will provide coverage over Indonesia and Southeast Asia from an orbital location of 118 deg. East.
Arianespace on track for 12 missions in 2017
With today's launch success, Arianespace maintains its 2017 mission cadence – which targets 12 missions from the Spaceport with the heavy-lift Ariane 5, medium-lift Soyuz and lightweight Vega. The next liftoff is scheduled for early March, using a Vega launcher to orbit Sentinel-2B, which is the latest addition to the European Union's Earth observation satellite fleet called Copernicus.

Arianespace has successfully launched two satellites: SKY Brasil-1 for AT&T/DIRECTV; and Telkom 3S for Telkom Indonesia as part of a turnkey contract with Thales Alenia Space.
The flight took place on Tuesday, February 14, 2017 at 6:39 p.m. (local time) from the Guiana Space Center, Europe's Spaceport in Kourou, French Guiana. Christophe Sirugue, French Minister of State for Industry, was on hand for the launch.
Today's launch was the second of the year for Arianespace and the first with the Ariane 5 heavy launcher, which also recorded its 77th successful mission in a row.

With a launch for two major regional operators, Arianespace confirms its position as the benchmark launch service provider for Latin America and Asia SKY Brasil-1 is the 10th satellite launched by Arianespace for AT&T/DIRECTV, a world leading provider of digital television programs. Its previous mission for this operator was in May 2015, with an Ariane 5 dual launch that orbited SKY Mexico-1 and DIRECTV-15. AT&T subsidiary DIRECTV Latin America provides services to more than 12.5 million subscribers, mainly in Venezuela, Argentina, Chile, Colombia and Brazil.
SKY Brasil-1 is a high-definition direct-to-home (DTH) TV broadcast satellite, covering Brazil and the north Atlantic Ocean.
Telkom 3S is the third satellite to be launched by Arianespace for Telkom Indonesia, this time as part of a turnkey contract with Thales Alenia Space. The previous satellites for this operator, Telkom 1 and Telkom 2, were launched by Arianespace in 1999 and 2005, respectively. All Telkom Indonesia satellites now in operation were orbited by Arianespace.
Telkom Indonesia is an Indonesian state-owned company that supplies telecommunications, information, media and entertainment services (TIMES) to millions of customers throughout the Indonesian archipelago. Telkom 3S will provide high-definition television (HDTV) broadcast services, as well as mobile communications and Internet applications, with a coverage zone spanning Indonesia, Southeast Asia and a portion of Malaysia.
Nearly half of all satellites built by Airbus Defence and Space and Thales Alenia Space have been orbited by Arianespace
Arianespace and Airbus Defence and Space have teamed up since the European launch services company was founded in 1980. SKY Brasil-1 is the 116th satellite built by Airbus Defence and Space (or its predecessors) to be launched by Arianespace, which has 17 more satellites produced by the company in its order book, not including the satellites in the OneWeb constellation.
Arianespace and Thales Alenia Space have worked together since 1981. Including Telkom 3S, Arianespace has launched 146 satellites built by Thales Alenia Space (or its predecessors), and has nine more satellites from this manufacturer in its order book.
Triple 7 for Ariane 5!
The first Ariane 5 flight of the year was also the 77th successful launch in a row of Ariane 5, a string of successes that reaches back to 2003 and clearly demonstrates the exceptional reliability of Arianespace's heavy launcher. This year's Arianespace mission manifest includes up to 7 Ariane 5 launches in 2017 – a "Triple 7" for Ariane 5!
Shortly after the announcement of the orbital injection of the two satellites, Stéphane Israël, Chairman and CEO of Arianespace, said: "Arianespace carried out its first Ariane 5 launch of the year this evening for our American and Indonesian customers, also marking the 77th successful launch in a row of our heavy launcher. We are both pleased and proud to have carried out this successful mission in the presence of Christophe Sirugue, French Minister of State for Industry; and Jean-Luc Moudenc, Mayor of Toulouse and President of the Community of Ariane Cities for 2017. We are honored by the ongoing trust expressed by the operators AT&T/DIRECTV, for whom we have orbited 10 satellites since 1993, and Telkom Indonesia, for whom we have launched all satellites now in operation. I would also like to thank our long-standing partners Airbus Defence and Space and Thales Alenia Space, who built the two satellites launched on this mission.
"Congratulations to all partners who contributed to the exceptional reliability and availability of our Ariane 5 launcher: the European Space Agency (ESA), which provides essential support for the Ariane program; Airbus Safran Launchers and the entire European launcher industry; CNES/CSG, our ground segment companies and all staff at the space center, who continue to work alongside us as we go from success to success. And of course I would like to congratulate everybody at Arianespace for this successful second launch of the year."

Насколько я понимаю, 3-й элемент 1-й строки содержит год (17 -> 2017), номер дня в году (45 -> 14 февраля) и время суток в дробной части. Чтобы получить хотя бы часы в пределах суток в UTC, дробь умножаем на 24 -> min 16.92834408 h, max 17.83873536 h.

Извините, я конечно умею рассказывать сказки и в своё время почитывал Брэдбери, но в реале машину времени пока ещё не создали...
Так что как-то так вытанцовывается, нет? Или покажите, в чём я неправ.

Из TLE никак не определяется
время получения измерений. Измерения получены когда-то (мы не знаем, когда). По этим полученным измерениям вычислена орбита, которая привязывается к какому-то моменту времени (чаще всего - к моменту прохождения восходящего узла). Вот этот момент и будет эпохой. И не важно, что в тот момент на этой орбите
физически объекта еще не было. То есть эпоха в TLE - это не время получения измерений. Это момент, к которому привязана орбита.

По этим полученным измерениям вычислена орбита, которая привязывается к какому-то моменту времени (чаще всего - к моменту прохождения восходящего узла).
Спойлер
ЦитироватьВ нашем конкретном случае можно вести речь только о баллистическом прогнозе орбиты, потому что измерений ещё нет. Момент прохождения восходящего узла вычисляется из измеренных или прогнозных элементов орбиты, т.е. орбита не может привязываться по сути к собственному элементу - привязываться можно к чему-то независимому. В данном случае момент времени прохождения КА восходящего узла объявляется точкой отсчета, от которой можно вести прогноз положения КА в пространстве как вперёд (чаще всего), так и назад - формулы баллистики этому не препятствуют.
Далее, движение КА по орбите - процесс периодический. Период - один из элементов орбиты. Период не может резко меняться, если к объекту не прикладывается внешняя сила. В нашем случае (для определенности возьмём КА 2017-007A) имеем
начальный набор - T = 632.3 m
обновлённый набор - T = 631.1 m
Видим, что разница ΔT = 1.2 m, т.е. невелика. Примем за оценку T среднее из двух значений - 631.7 m. Зная период и эпоху, можем вычислить время прохождения ВУ на следующем витке. Берем эпоху начального набора 17045.70623437, прибавляем средний период (в долях суток), имеем
(631.7/1440) + 17045.70623437 = 17046.144914925555555555555555556
Эпоха обновлённого набора 17046.48121396. Разность эпох видна невооруженным глазом и составляет 0.33629903444444444444444444444444 суток или 484.2706096 m.
Допустим, что наборы отличаются между собой не на один виток, а на два. В этом случае имеем
2*(631.7/1440) + 17045.70623437 = 17046.583595481111111111111111111.
Тогда разность с обновлённым набором составит 0.10238152111111111111111111111111 суток или 147.4293904 m.
В итоге имеем в двух наборах коррелирующиеся между собой периоды обращения КА и совершенно не соответствующие друг другу времена прохождения КА восходящих узлов орбиты. Небесная механика – наука точная, её матаппарат за более чем 4 века разработан очень подробно. Как с её точки зрения при по сути неизменной орбите (за два витка) так могут отличаться моменты прохождения восходящих узлов. Далее, прогноз орбиты перед пуском делается достаточно точно, разница времени старта от расчетного даже в несколько секунд не сильно влияет на элементы орбиты. В нашем случае выведение по данным Arianespace можно считать прецизионным. Элементы орбиты по двум наборам хорошо коррелируют (или даже совпадают) между собой кроме эпох. «Кто-то вро́т» (почти Цы). Остаюсь при своём мнении – эпоха первичного набора TLE ошибочна.
Новые TLE - два объекта начали карабкаться на верхотуру

Пока можно сказать, что селектированы две группы объектов
- пассивные B и D (последняя ступень РН и проставка SYLDA)
- активные A и C (пассажиры - SkyBrasil-1, Telkom 3S).
Ждём идентификации с переназначениями и наименованиями

Потому что набор на эпоху 17046.48121396 выдан не на момент прохождения узла. Такое тоже бывает.
Ув.
Безумный Шляпник, извините, я Вам отвечу несколько попозже...
Обновили наборы TLE на A - C. D - без изменений, полагаю - это посл. ст. РН. A и B только уточнены. Резко изменил орбиту C - прёт наверх, уменьшает наклонение.
