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.
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.
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 degrees East as part of a Korean government national programme.
