Arianespace successfully launched 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). The launch marked the 103rd Ariane 5 mission.

ISRO’s GSAT-31 satellite will provide Ku-band transponder capacity for the Indian mainland and islands.
Arianespace said up to five Ariane 5 dual launches are planned in 2019, to orbit a total of 10 geostationary satellites.
