Celeste’s First Satellites Launched to Test LEO Navigation for Enhanced Galileo
On March 28, 2026, the European Space Agency (ESA) took a significant stride in bolstering Europe’s ambition for more resilient satellite navigation with the successful launch of the first two satellites for the Celeste mission. Lifted off from New Zealand aboard Rocket Lab’s Electron rocket, their primary objective is to begin testing a complementary low Earth orbit (LEO) layer for the Galileo navigation system.
The Celeste project aims to reduce reliance on existing satellite navigation systems and provide more robust and dependable positioning services. The complementary signals from LEO are anticipated to improve positioning accuracy, particularly in urban and obstructed environments.
This launch advances Europe’s aspirations in the satellite navigation sector, building a foundation for future applications and services. The success of Celeste underscores Europe’s commitment to playing a leading role in the evolution of space-based navigation technology.
