The mission

The Celeste LEO-PNT in-orbit demonstrator mission will feature a 11-satellite constellation that will fly close to Earth to test innovative signals across various frequency bands. It will assess how a low Earth orbit fleet can work in combination with Galileo, EGNOS and other GNSS in a multi-layer approach to optimise the provision of services, increasing overall PNT resilience and robustness, and enabling new services.

FutureNAV

ESA’s Celeste LEO-PNT in-orbit demonstration mission is central to FutureNAV, a programme that enables the agency to respond to trends and needs in the field of navigation, ultimately allowing Europe to stay on the cutting edge of satellite navigation technology.
