At 10:14 CET on 28 March, the first two satellites of ESA’s Celeste LEO-PNT in-orbit demonstration mission lifted off aboard a Rocket Lab Electron rocket from Māhia, New Zealand.

Celeste is Europe’s first initiative to bring satellite navigation into low Earth orbit (LEO). By testing next-generation technologies and new frequency bands, it will help shape the future of positioning, navigation and timing services.

Flying closer to Earth, Celeste will demonstrate how a complementary LEO layer can strengthen Europe’s Galileo system in medium Earth orbit — improving resilience, enhancing performance and enabling new services.
