Eagle-1 is a future European technology demonstration satellite for in-orbit demonstration of space-based quantum key distribution. The satellite was developed by a consortium of companies led by the Luxembourg-headquartered SES for the European Union (EU) and the European Space Agency (ESA). Eagle-1 is the first step in development of a sovereign European quantum communication infrastructure, specifically the EuroQCI network. The satellite will be launched to low-Earth orbit on a Vega C rocket from the Guiana Space Centre in French Guiana in late 2026 or early 2027.
