Europe Advances LEO Satellite Navigation with Celeste’s First Two Satellites Launched
The European Space Agency (ESA) took a significant step forward on March 28, 2026, in its ambition to bolster Europe’s resilient satellite navigation capabilities with the launch of the first two satellites for the Celeste mission. Lifted off from New Zealand aboard Rocket Lab’s Electron rocket, these satellites are set to begin testing a complementary low Earth orbit (LEO) layer for Galileo.
This demonstration mission aims to validate a LEO-based navigation system that will work alongside Galileo, which currently operates in medium Earth orbit. By establishing a constellation of smaller satellites in LEO, the project seeks to offer more precise and robust positioning services. This initiative is a crucial part of ESA’s strategy to reduce reliance on existing systems and enhance Europe’s independent satellite navigation infrastructure.
