Arianespace and EUMETSAT announce the signature of a launch contract for the first Metop-SG satellites

Arianespace and EUMETSAT announce the signature of a contract entrusting Arianespace with the launch of the first two Metop-SG satellites of the EUMETSAT Polar System of Second Generation (EPS-SG), plus an option for the launch of a third satellite, to be performed from the Guiana Space Center – Europe’s Spaceport in Kourou, French Guiana.


The launches are scheduled in the 2021-2023 timeframe for METOP-SG A1 and METOP-SG B1 – with these missions using the same Soyuz STB launcher configuration as for EUMETSAT’s Metop-C (the third and last Metop first-generation satellite, which is manifested for launch in autumn 2018).

METOP-SG A1 and METOP-SG B1 will be built by Airbus Defence and Space, based on the AstroBus platform. Each satellite will have a four-ton mass and will be placed into a sun-Synchronous orbit at an altitude of approximately 800 km.

The contract includes an option for a Soyuz launch with a third Metop-SG satellite, for which EUMETSAT is also offered the possibility to use Ariane 62, a version of Europe’s next generation Ariane 6 launch system, expected to be available in this timeframe.

The EUMETSAT Polar System of Second Generation will replace the first-generation EUMETSAT Polar System in the 2021-2023 timeframe and deliver more, and even better, observations than the current Metop satellites. With three successive pairs of Metop-SG A and Metop-SG B satellites carrying two different sets of innovative instruments and flying in the same mid-morning polar orbit, EPS-SG is expected to be utilized for at least 21 years by EUMETSAT.

EUMETSAT Director-General Alain Ratier said: “The signature of this contract is a key milestone towards the initial deployment of our EPS-SG system. We know we can count on the reliability of Soyuz and on Arianespace’s services and unique experience in handling complex Earth observation satellites like Metop.”

Arianespace Chief Executive Officer Stéphane Israël added: “We are proud and honored of the confidence placed by EUMETSAT in Arianespace’s launch solutions. Entrusting Arianespace with the initial launches of EUMETSAT’s second-generation, advanced meteorological satellites in its EPS-SG series reflects the exceptional nature of our partnership. Not only does it enable Arianespace to continue providing secured and autonomous access to space for European institutions, it also enables us – through this project – to contribute to the sustainable development of our planet, which is one of the greatest challenges of our time.”

About Arianespace

Arianespace uses space to make life better on Earth by providing launch services for all types of satellites into all orbits. It has orbited more than 550 satellites since 1980, using its family of three launchers, Ariane, Soyuz and Vega, from launch sites in French Guiana (South America) and Baikonur, Kazakhstan. Arianespace is headquartered in Evry, near Paris, and has a technical facility at the Guiana Space Center, Europe’s Spaceport in French Guiana, plus local offices in Washington, D.C., Tokyo and Singapore. Arianespace is a subsidiary of ArianeGroup, which holds 74% of its share capital, with the balance held by 17 other shareholders from the European launcher industry.

两卫星重量加起来约9吨,所以分别发射。A星2022年,B星2023年。
