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



Flight VA246 lift off

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 ECA launch vehicle from Ariane Launch Complex No. 3 (ELA 3) at Guiana Space Centre in Kourou, French Guiana, on 4 December 2018, at 20:37 UTC (17:37 Guiana time).



Successful Mission Arianespace Flight VA246– GSAT-11 and GEO-KOMPSAT-2A

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



GSAT-11

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.
