Arianespace to launch GEO-KOMPSAT 2A and 2B satellites for Korea Aerospace Research Institute

The Korea Aerospace Research Institute (KARI) has chosen Arianespace to launch the two satellites in its GEO-KOMPSAT-2 program. Mr. Jacques Breton, Senior Vice President, Sales & Customers of Arianespace and Mr. CHO Gwangrae, President of KARI, have signed today the launch contract for GEOKOMPSAT-2A & -2B.

GEO-KOMPSAT-2A (GK2A) and GEO-KOMPSAT-2B (GK2B) will be orbited by Ariane 5 launchers in May 2018 and March 2019 from the Guiana Space Center, Europe’s Spaceport in Kourou, French Guiana.

For nearly 25 years now, Arianespace and KOREA’s satellite technology research centers have developed a sound relationship, with the launch of both scientific microsatellites and the COMS multi-mission satellite. GEO-KOMPSAT-2A (GK2A) and GEO-KOMPSAT-2B (GK2B) will be the seventh and eighth satellites launched by Arianespace for South Korea.

Each of the GEO-KOMPSAT-2 satellites will weigh about 3,500 kg. at launch, and will be positioned in geostationary orbit at 128.2° East.

The satellites will be built by KARI at its facility in Daejeon, South Korea. The two governmental GEO-KOMPSAT-2 satellites will primarily perform meteorological observation and space weather monitoring (GK2A), and ocean and Earth environmental monitoring (GK2B).

Arianespace Chairman and CEO Stéphane Israël welcomed the contract signing, saying: “Arianespace is extremely proud of its selection by the Korean space agency, KARI. Our last launch for KARI occurred in 2010. Now, we have been chosen again by KARI to launch these two impressive meteorological observation missions. Contributing to Korean space achievements is a great honor for Arianespace. I would once again like to thank the Korea Aerospace Research Institute for selecting us. Arianespace will deliver.”

Flight VA246: Arianespace serves the Indian and Korean space programs with its launch of GSAT-11 for ISRO and GEO-KOMPSAT-2A for KARI

For its 10th launch of 2018, the sixth of the year using an Ariane 5 vehicle, Arianespace will serve the space ambitions of two leading agencies by orbiting GSAT-11 for the Indian Space Research Organisation (ISRO) and GEO-KOMPSAT-2A for the Korea Aerospace Research Institute (KARI).

With this mission dedicated to space applications for telecommunications, weather and climate studies, Arianespace once again contributes to a better life on Earth.

Flight VA246 will be performed from Ariane Launch Complex No. 3 (ELA 3) in Kourou, French Guiana.

The Launch Readiness Review (LRR) will take place on Monday, December 3, 2018 in Kourou to authorize the start of operations for the final countdown.

To be installed as Ariane 5’s upper passenger, GSAT-11 is an operational telecommunication satellite designed and manufactured by ISRO.

To be positioned at 74° East, GSAT-11  ̶  ISRO’s largest and heaviest communication satellite ever  ̶  is configured on its next-generation I-6K structure to provide communications services from geostationary orbit in Ku- and Ka-bands in both forward and return links.

Offering a multi-spot beam coverage over the Indian mainland and nearby islands, GSAT-11 will bring significant advantages to users when compared with existing INSAT/GSAT satellite systems. Its designed lifetime is more than 15 years.

With two ISRO’s additional satellites remaining in Arianespace’s order book (GSAT-31 and GSAT-30), the launch of GSAT-11 is to be another vivid demonstration of the strong bond uniting Europe and India in space cooperation.

The GEO-KOMPSAT-2 program is a national program of the Korean Government to develop and operate two civilian geostationary satellites, GEO-KOMPSAT-2A and -2B.

Positioned on Ariane 5 as Flight VA246’s lower passenger, GEO-KOMPSAT-2A is designed to conduct meteorological and space weather monitoring missions whereas GEO-KOMPSAT-2B is to carry out Earth environment monitoring and ocean monitoring missions.

Covering the Asia-Pacific region, this weather satellite will be stationed at the 128.2° East orbital location for a 10-year nominal life in service. Developed by KARI at its facility in Daejeon, South-Korea, GEO-KOMPSAT-2A will be KARI’s second satellite, and the seventh for South-Korea to be lofted by Arianespace.

Prior to Flight VA246, Arianespace has orbited 588th satellites, out of which 115 were launched for eight space agencies around the world (Europe, France, Italy, Sweden, U.S., India, Korea and Japan).

GSAT-11 and GEO-KOMPSAT-2A will be the 589th and 590th satellites to be orbited by Arianespace.

Arianespace integrates GSAT-11 and GEO-KOMPSAT-2A for next week’s Ariane 5 launch

The Ariane 5 launch vehicle for Arianespace’s 10th mission of 2018 is now fully assembled following integration of its two satellite passengers at the Spaceport in French Guiana.

During activity in Ariane 5’s Final Assembly Building, the upper payload component – containing GSAT-11, mounted on its SYLDA dispenser system and protected by an ogive-shaped fairing – was lowered into position over GEO-KOMPSAT-2A, which was previously installed atop the launcher’s central core stage.

This step clears the way for final checkout, which will enable the launch readiness review to be conducted on November 30, followed by Ariane 5’s rollout to the Spaceport’s ELA-3 launch zone the following Monday, and an early evening liftoff on Tuesday, December 4.

The upcoming mission is designated Flight VA246 in Arianespace’s numbering system, and it will inject the two payloads into geostationary transfer orbit.

At the service of Indian and South Korean space agencies

To be deployed first during the 33-minute flight sequence is GSAT-11, which was designed and assembled by the Indian Space Research Organisation (ISRO). Operating from a final orbital position at 74 deg. East, this advanced communications satellite will deliver multi-spot beam coverage over the Indian mainland and nearby islands – bringing significant advantages to the user community when compared with India’s existing INSAT/GSAT satellite systems.

Ariane 5’s second passenger – GEO-KOMPSAT-2A – was produced by the Korea Aerospace Research Institute (KARI). It will be used primarily to provide meteorological observation and space weather monitoring, stationed in orbit at 128.2 deg. East.

Flight VA246 will mark Arianespace’s 10th mission performed in 2018, and the company’s sixth this year using a heavy-lift Ariane 5 – which is one of three launch vehicles operated by Arianespace at the Spaceport, along with the medium-lift Soyuz and light-lift Vega.

Approval is given for Arianespace’s Ariane 5 launch with GSAT-11 and GEO-KOMPSAT-2A

Arianespace’s next Ariane 5 flight has been authorized for liftoff on December 4 following today’s launch readiness review, which was conducted at the Spaceport in French Guiana.

This milestone confirmed that the heavy-lift launcher and its dual-satellite payload are flight-ready, along with the Spaceport’s infrastructure and the network of downrange tracking stations.

With approval granted, Ariane 5 is cleared for its December 3 rollout from the Final Assembly Building to the ELA-3 launch zone. Liftoff will occur the following day during a 1-hour, 16-minute launch window that opens at 5:37 p.m. local time in French Guiana.

Dual-payload performance

Ariane 5 will deliver a lift performance of more than 10,200 kg. on the mission to geostationary transfer orbit (GTO), which is designated Flight VA246. This total includes the GSAT-11 and GEO-KOMPSAT-2A satellite passengers, and also factors in the workhorse vehicle’s dual-payload deployment system and integration hardware.

The GSAT-11 satellite – produced by the Indian Space Research Organisation (ISRO) – will ride in the upper position of Ariane 5’s payload arrangement, to be deployed first during the 33-min. flight sequence. To be positioned at 74 deg. East, GSAT-11 is configured to provide communications services from geostationary orbit.

Located below GSAT-11 in the launcher payload arrangement is the mission’s lower passenger – GEO-KOMPSAT-2A – which was developed by the Korea Aerospace Research Institute (KARI). It was designed to conduct meteorological and space weather monitoring missions, and will be stationed at the 128.2 deg. East orbital location.

Ariane 5 delivers for two special Arianespace partners: the space agencies of India and South Korea

Arianespace’s 10th mission of 2018 orbited satellite payloads today for the Indian Space Research Organisation (ISRO) and the Korea Aerospace Research Institute (KARI), using the workhorse Ariane 5 on a launch performed from the Spaceport in French Guiana.

Designated Flight VA246 in Arianespace’s launcher family numbering system, it delivered the ISRO GSAT-11 relay platform for Ku- and Ka-band communications, along with KARI’s GEO-KOMPSAT-2A – which is to provide meteorological and space weather monitoring data.

“I want to express my deepest gratitude to two very special partners since the beginning of their space ambitions: ISRO and KARI,” said Arianespace CEO Stéphane Israël in post-launch comments from the Spaceport.

Continuing the long relationship with India’s ISRO

Israël noted that GSAT-11 was the 22nd ISRO satellite orbited by Arianespace and Ariane-series launchers, tracing the relationship back to India’s APPLE small experimental communications spacecraft, which had a liftoff mass of 670-kg. and was lofted in 1981 by an Ariane 1 version. On today’s Ariane 5 mission, GSAT-11 weighed in at 5,854.6 kg. – the largest and heaviest satellite ever built by the Indian space agency.

Deployed first during Ariane 5’s 33-minute mission to geostationary transfer orbit, GSAT-11 will be positioned at 74 deg. East, providing communications services in Ku- and Ka-bands in both forward and return links. The satellite was designed and manufactured by ISRO, with its multi-spot beam coverage over the Indian mainland and nearby islands to bring significant advantages to users when compared with existing India’s INSAT/GSAT satellite systems. GSAT-11’s design lifetime is more than 15 years.

South Korea’s seventh satellite orbited by Arianespace

GEO-KOMPSAT-2A was carried in Ariane 5’s lower payload position and released second in the sequence for Flight VA246. Developed by KARI at its South Korean facility in Daejeon, this 3,507.2-kg. satellite will deliver meteorological and space weather monitoring from an orbital position of 128.2 deg. East as part of a Korean government national program.

“Arianespace is proud to maintain such a close bond with South Korea,” Israël stated, adding that Flight VA246 marked the seventh time South Korea’s flag has appeared on the fairing of an Arianespace launch vehicle.

In addition to the Ariane 5’s payload fairing logos representing Flight VA246’s two satellite passengers, also included was a decal recognizing the French city of Les Mureaux – home to the ArianeGroup site responsible for integration of Ariane 5 cryogenic main stages today, and for Ariane 6 launchers in the future. Les Mureaux is completing its year-long presidency for the Community of Ariane Cities, a non-profit association that brings together cities and their industrial companies involved in the Ariane program.

The rapid tempo of Arianespace launches

CEO Stéphane Israël noted that Arianespace has once again confirmed its flexibility and reliability by performing five launches in two and a half months – from September 25 to December 4 – with liftoffs coming every two weeks since early November. “What an impressive tempo,” he concluded, noting that today’s Flight VA246’s orbiting of the GSAT-11 and GEO-KOMPSAT-2A satellites for connectivity and weather data gathering fulfills Arianespace’s motto: “Space for a better life on Earth.”

Arianespace has one more mission scheduled before year-end, using the Soyuz medium-lift member of its launcher family to orbit the CSO-1 spacecraft for France’s DGA (Direction générale de l’armement) defense procurement agency and the French CNES space agency.

Arianespace orbits GSAT-11 and GEO-KOMPSAT-2A for Indian and Korean space agencies: ISRO and KARI

Arianespace has successfully orbited two satellites: GSAT-11 for ISRO (Indian Space Research Organisation), and GEO-KOMPSAT-2A for KARI (Korea Aerospace Research Institute).

With this mission dedicated to space applications for telecommunications and meteorology, Arianespace once again contributes to the improvement of life on Earth.

The sixth Ariane 5 launch of the year took place on Tuesday, December 4 at 5:37 pm (local time) from the Guiana Space Center (CSG), Europe’s Spaceport in French Guiana (South America).

This 10th mission in 2018 reflects the availability and flexibility of Arianespace, which has performed a launch every two weeks since November 6.

Arianespace, a key partner of ISRO

Since the launch of India’s APPLE experimental satellite on Ariane Flight L03 in 1981, Arianespace has won nearly all of India’s geostationary orbit launch contracts opened to non-Indian launch vehicles, and has signed 24 launch contracts with the Indian space agency.

GSAT-11 is the 22nd satellite from ISRO to be launched by Arianespace, and the largest and heaviest satellite ever built by India’s space agency. Arianespace has two other ISRO satellites in its order book to launch: GSAT-30 and GSAT-31. The latter, GSAT-31, will be lofted by Arianespace early next year.

GSAT-11, configured on the new-generation I6-K satellite bus, will provide communications services with multi-spot beam coverage of the Indian mainland and nearby islands. With this new satellite, ISRO will help bridge the digital divide in India within the scope of a program that capitalizes on space technology to support national development, while also pursuing space science research and planetary exploration.

Arianespace helps South Korea develop its ambitious space program

GEO-KOMPSAT-2A is the second satellite from the South Korean space agency KARI to be orbited by Arianespace, following the multi-mission COMS (Communication, Ocean, Meteorological Satellite), launched in 2010 by an Ariane 5.

Arianespace has two Earth observation satellites from KARI in its order book for future launches: GEO-KOMPSAT-2B on Ariane 5 and KOMPSAT-7 on Vega C.

Since launching South Korea’s first satellites, KITSAT-1A in 1992 and KITSAT-2 in 1993 using Ariane 4 launch vehicles, Arianespace has become a major partner to the Korean space program.

Arianespace also has orbited three satellites for the telecom operator kt sat: KOREASAT-3 in 1999, KOREASAT-6 in 2010 and KOREASAT-7 in 2017.

GEO-KOMPSAT-2 is a national program developed by KARI for the South Korean government, involving the development and operation of two civilian geostationary satellites, GEO-KOMPSAT-2A and 2B.

GEO-KOMPSAT-2A is designed to conduct meteorological and space weather monitoring missions.

Another launch for a better life on Earth

With this latest launch, Arianespace continues its vocation of using its launcher family to make life better on Earth. The GSAT-11 satellite, which will help reduce the digital divide in India, is only the latest in a long line of communications satellites that connect people and enhance Internet access worldwide, including for people on the move. With the COP24 Climate Change Conference now taking place in Poland, the GEO-KOMPSAT-2A satellite reflects Arianespace’s commitment to sustainable development. It is the 67th Earth observation satellite to be launched by Arianespace.

A launch every two weeks

Flight VA246 is the 10th launch performed by Arianespace in 2018: six using Ariane 5s, two with Vega and two with Soyuz. In the fourth quarter of the year, Arianespace has once again proven its flexibility and reliability by carrying out five launches in two-and-a-half months (September 25 – December 4), with launches coming every two weeks since early November. The last launch of the year will continue this momentum, as Arianespace will use a Soyuz rocket to launch the CSO-1 spacecraft for the French defense procurement agency DGA (Direction générale de l’armement) and the French space agency CNES.

Shortly after the orbital injection of the GSAT-11 and GEO-KOMPSAT-2A satellites, Stéphane Israël, Chief Executive Officer of Arianespace, said: “With this 10th launch of the year, Arianespace is glad to support two major space agencies: ISRO of India and KARI of South Korea. We are very honored by the renewed confidence of ISRO. GSAT-11 is the heaviest communications satellite ever built by the agency, and the first to be carried in the upper position on Ariane 5.

We are also very proud to launch the GEO-KOMPSAT-2A weather satellite, in our second mission for the Korean space agency KARI. My congratulations to these agencies for the construction of these advanced satellites, which will help reduce the digital divide in India and improve Korean weather forecasts.

Today’s launch marks the latest mission for a better life on Earth, and we are both pleased and proud to have performed it in the presence of the Chairman of ISRO, Dr. K Sivan; of the Vice President of KARI, Mr. Sang Ryool Lee.  This launch also took place in the presence of Mr. François Garay, Mayor of Les Mureaux and President of the Community of Ariane Cities in 2018, whom we thank for his constant support.

“I would like to thank all of our partners in this latest success, which confirms the exceptional reliability of Ariane 5: ArianeGroup’s teams and all companies involved in the construction of Ariane, ESA, CNES, our ground segment companies and all staff at the launch base. And congratulations to everybody at Arianespace for this perfect penultimate launch of the year and for maintaining such a sustained and successful rapid pace.”

GSAT-11

The GSAT-11 satellite was built by ISRO (Indian Space Research Organisation) on the new-generation I-6K satellite bus.

Positioned at 74° East in geostationary orbit, it will provide Ku- and Ka-band communications services in both forward and return links.

The satellite weighed 5,854.6 kg. at launch and it offers a design life of 15 years.

GEO-KOMPSAT-2A

The GEO-KOMPSAT-2A satellite was built by KARI (Korea Aerospace Research Institute) at its facility in Daejeon, South Korea.

Positioned at 128.2° East, it will cover the Asia-Pacific region.

The satellite weighed 3,507.2 kg. at launch, and it offers a design life exceeding 10 years.

India’s heaviest communication satellite GSAT-11 launched successfully from French Guiana

Indian Space Research Organisation’s (ISRO) heaviest and most-advanced high throughput communication satellite GSAT-11 was successfully launched from the Spaceport in French Guiana during the early hours today.

The launch vehicle Ariane 5 VA-246 lifted off from Kourou Launch Base, French Guiana at 02:07 am (IST) carrying India’s GSAT-11 and South Korea’s GEO-KOMPSAT-2A satellites, as scheduled. Ariane 5 is one of three launch vehicles operated by Arianespace along with Soyuz and Vega.

After a 30-min flight, GSAT-11 separated from the Ariane 5 upper stage in an elliptical Geosynchronous Transfer Orbit.  The achieved orbit was very close to the intended one.

The 5854-kg GSAT-11 will provide high data rate connectivity to users of Indian mainland and islands through 32 user beams in Ku-band and 8 hub beams in Ka-band.

“GSAT-11 will boost the broadband connectivity to rural and inaccessible Gram Panchayats in the country coming under the Bharat Net Project, which is part of Digital India Programme,” ISRO Chairman Dr K Sivan said.

The Bharat Net Project aims to enhance the public welfare schemes like e-banking, e-health, e-governance among others.

He said GSAT-11 will act as a forerunner to all future high throughput communication satellites. “Today’s successful mission has boosted the confidence of the entire team,” Dr Sivan added.

Post-separation, ISRO's Master Control Facility at Hassan in Karnataka took over the command and control of GSAT-11 and found its health parameters normal.

The scientists will undertake phase-wise orbit-raising manoeuvres in the days ahead to place the satellite in the Geostationary Orbit (36,000 km above the equator) using its on-board propulsion systems. GSAT-11 will be positioned at 74-degree east longitude in the geostationary orbit.

Subsequently, the two solar arrays and four antenna reflectors of GSAT-11 will be deployed in orbit.  The satellite will be operational after the successful completion of all in-orbit tests.

In the last 21 days, ISRO successfully completed three satellite and two launch vehicle missions.

The 6th Ariane 5 launch of the year is a success

Kourou, 4 December 2018

 Ariane 5 placed two satellites in orbit for its sixth launch of 2018
 This was the year’s final launch for Ariane 5, which placed 13 satellites in orbit in 2018

In its final launch of 2018, Ariane 5 placed two satellites in geostationary transfer orbit (GTO),
lifting off from the European spaceport in Kourou (French Guiana). GSAT-11 is a
telecommunication satellite, while GEO-KOMPSAT-2A is designed to provide Earth and space
weather observation.

This launch placed two satellites in orbit, with a total mass of 9,362 kg. The total performance
required of the launcher was 10,297 kg, with the ACU (payload adapters), the SYLDA (Ariane
dual launch system) and the LVA 3936 (Launch Vehicle Adaptor). The orbit was optimized thanks
to the power of the Ariane 5 ECA launcher, which enabled the payloads to be placed in a transfer
orbit with a reduced inclination of 3.5° (instead of the usual 6°).

“With these 6 launches in 2018, Ariane 5 once again demonstrated its performance and flexibility,
notably by placing – for the third time – 4 Galileo satellites in orbit, by placing BepiColombo in its
release orbit on the way to Mercury, by celebrating its 100th launch and by once again
demonstrating its ability to launch more than 10 metric tons to geostationary orbit. I extend my
warmest thanks to the teams at ArianeGroup and those of our subsidiary Arianespace for the
work accomplished on this sixth launch of Ariane 5, marking the end of an intense 2018. The
Ariane 5 successes, are paving the way for the future successes of Ariane 6. I would once again
like to express my gratitude to the European Space Agency and the CNES for their confidence
and their unflagging support,” said Alain Charmeau, CEO of ArianeGroup.

As the industrial lead contractor for development and operation of the Ariane 5 and Ariane 6
launchers, ArianeGroup coordinates an industrial network of more than 600 companies in 13
European countries, including more than 350 Small and Medium Enterprises (SMEs).
ArianeGroup oversees all the industrial activities, from the performance improvements and
studies necessary for Ariane 5 up to its production, the provision of data or software specific to
each mission, without forgetting marketing activities via Arianespace. This chain includes
equipment and structures, engines manufacturing, integration of the various stages and finally
launcher integration in French Guiana.

The Ariane 246 flight in figures:

 102nd launch of an Ariane 5
 77h consecutive nominal ignition of the Vulcain® 2 engine
 102nd consecutive nominal ignition of the EAP solid propellant boosters
 142nd consecutive nominal ignition of the HM7B engine

Congrats to Arianespace with this latest launch success.

Despite the great video coverage, the supply of pics of the launch campaign has gone downhill significantly. There are only a few pics on the Arianespace website; no pics at all on the CNES Flickr page (which used to provide up to 100+ pics), the gallery of launches on the CNES site itself has yet to cover 2018, and there is no coverage anymore on the "CSG preparation lancement" website, which seems to be offline since early this year or so.  :'(

Have all these services been ended to save money in the current difficult launchers market Arianespace is facing?

First space weather ‘piggyback’ kit launched into space

The first ESA-funded space weather monitoring instrument was launched on 4 December 2018, hitching a ride on South Korea’s new geostationary satellite, GEO-KOMPSAT-2 – the Geostationary Korea Multi-Purpose Satellite-2A.

The satellite, seen in this image, was lofted into orbit on an Ariane rocket from Europe’s Spaceport in Kourou, French Guiana, and will provide meteorological monitoring over the Asia-Pacific region as well as data on space weather.

‘Space weather’ describes the constantly changing conditions in space as a result of the unpredictable behaviour of our active Sun.

This dynamic solar activity changes the space environment, causing variations in magnetic and electric fields, and levels of high-energy particles and radiation around our planet. Such changes can cause impair satellites, disturb telecommunication and satellite navigation, and damage with crucial infrastructure on Earth, such as power grids.

ESA’s Service Oriented Spacecraft Magnetometer (SOSMAG) instrument has four tiny sensors that will measure Earth’s magnetic field and provide data on how space weather affects it.

The SOSMAG kit is designed ultimately to be mounted on a variety of different spacecraft, in an array of orbits, which together will give a fuller picture of Earth’s space weather environment. These ‘hosted payloads’ boost efficiency and reduce cost, while providing critical data to be fed into ESA’s Space Weather Services Network.

Find out more about the network, ESA’s future Distributed Space Weather Sensor System, and the upcoming Lagrange mission to monitor the Sun, all part of the Agency’s plan to monitor hazards in space and one day to mitigate them.

The SOSMAG instrument is funded by ESA’s Space Situational Awareness programme, and was built by an industrial consortium consisting of the Austrian Academy of Sciences, the Space Research Institute (IWF), Magson GmbH, the Institut für Geophysik und Extraterrestrische Physik of TU Braunschweig and the The Blackett Laboratory of Imperial College London (ICL).

Orbit raising manoeuvres have been performed on GSAT-11

After the successful launch of GSAT-11 into a Geosynchronous Transfer Orbit by Ariane 5 VA246 vehicle on December 05, 2018, three orbit raising manoeuvres have been performed by firing the satellite’s onboard propulsion system for a cumulative duration of more than four hours.  Consequently, the orbit of GSAT-11 with a perigee (nearest point to earth) of 32,657 km and an apogee (farthest point to earth) of 35,850 km, is very close to its designated Orbit.  One more manoeuvre will be performed tomorrow (December 09, 2018) to achieve the operational circular geostationary orbit of 35,786 km.

AFAIK Ariane launcher don't have a serial number.
But it was: Ariane family launch 246 (VA246)
- the 102th Ariane 5 launch
- AFAIK the 69th Ariane 5 ECA (the 8th Ariane 5 ECA of the PB+ batch of 15 Ariane5 ECA)
I don't have inside info, so I could be wrong.

They have a batch number, variant SN and total SN.
Jester and other have posted these in the past. The info is generally not made widely known to the public but is public info.
