Celeres

Celeres, formerly GTD Space & Security, is a European provider of software and systems for critical missions. The company designs, implements, integrates, validates and supports technology used in demanding environments, where reliable operation is essential. Its work spans four sectors: space, defence, transport and the public sector.

In space, Celeres provides IT engineering and systems for space-sector organisations and supports operations connected to launch pads and mission campaigns. Its work includes consolidating operational IT systems for launch and flight-safety activities, including the i-CDO project within the CSG-NG program. In defence, the company develops and supports systems and infrastructure, including sovereign satellite-control initiatives. Its transport services include IT and systems integration, while its public-sector work focuses on secure, flexible and high-performance public infrastructure.

Headquartered in Barcelona, Celeres has offices across France and Germany and operates at spaceport locations in French Guiana, Norway and Sweden. Its teams work close to mission sites, providing technical expertise and operational support for systems that must perform reliably.
