Arianespace has successfully orbited two telecommunications satellites: the Saudi Geostationary Satellite 1/Hellas Sat 4 condosat for operators KACST and Hellas Sat; and GSAT-31 for the Indian Space Research Organisation (ISRO).

Arianespace’s first launch of the year took place on Tuesday, February 5 at 6:01 p.m. (local time) from the Guiana Space Center (CSG), Europe’s Spaceport in French Guiana (South America).

Today’s launch was the 103rd Ariane 5 mission, bringing the number of geostationary satellites launched by Arianespace to 374.

Arianespace Flight VA247 – GSAT-31 – Successful Mission

Following the announcement of this first successful launch of the year, Stéphane Israël, Chief Executive Officer of Arianespace, said: “This year we kick off the 40th anniversary celebration of the first launch of Europe’s Ariane rocket with a successful launch of Ariane 5. Through this emblematic flight, Arianespace underscores the reliability of our heavy launcher, the benchmark in the launch segment for geostationary telecommunications satellites. By carrying out a mission for long-lasting customers from three continents – Arabsat, KACST, Hellas Sat and ISRO – we continue to prove the attractiveness of Arianespace’s launch services for customers from around the world, both institutional and commercial.”

Saudi Geostationary Satellite 1/Hellas Sat 4

Composed of two payloads, Saudi Geostationary Satellite 1/Hellas Sat 4, also called HS- 4/SGS-1, is a geostationary condosat for KACST (King Abdulaziz City for Science and Technology – Saudi Arabia) and Hellas Sat (Greece – Cyprus). To be installed as Flight VA247’s upper passenger, HS-4/SGS-1 will provide telecommunications capabilities, including television, Internet, telephone and secure communications in the Middle East, South Africa and Europe.

The Saudi Geostationary Satellite 1 communications payload will provide advanced Ka-band spot beam communications services for the Kingdom of Saudi Arabia’s KACST, including secure communications for the Gulf Cooperative Council region. KACST is an independent scientific organization of the government of Saudi Arabia that is responsible for the promotion of science and technology in the Kingdom.


Following the launch of GSAT-11 for the Indian Space Research Organisation (ISRO) using the yearending Ariane 5 of 2018, Arianespace will orbit GSAT-31 utilizing the initial Ariane 5 in 2019.

To be installed as Flight VA247’s lower passenger, GSAT-31 is a telecommunications satellite designed and manufactured by the Indian space agency. To be positioned at a longitude of 48° East, GSAT-31 is configured on ISRO’s enhanced I-2K bus structure to provide communications services from geostationary orbit in Ku-band for a lifetime greater than 15 years.

By operating GSAT-31, ISRO will – once again – foster the use of space to help bridge the digital divide in the Indian subcontinent as part of its ambitious space program, whose objectives are to develop India while pursuing science research and planetary exploration.
