GEIPAN (Groupe d’études et d’informations sur les phénomènes aérospatiaux non identifiés) is France’s UAP investigation unit, operating since 1977 within the French space agency CNES. As of 2026 it has archived approximately 5,300 cases, of which 2-3% remain unexplained (see src-academic-uap-stigma-2026-04). GEIPAN is the longest continuously running government UAP program in the world and is cited frequently as a model for institutional UAP investigation in international comparisons.
Per src-canada-sky-canada-project-2025-02, MP larry-maguire names France and the United States as the two key international partners with which a future Canadian UAP lead would coordinate — placing GEIPAN alongside aaro as the institutional templates for a Canadian body.
