The European Union Agency for the Space Programme (EUSPA) is a space agency, managing the European Union Space Programme as one of the agencies of the European Union (EU). It was initially created as the European Global Navigation Satellite Systems Supervisory Authority (GSA) in 2004, reorganised into the European Global Navigation Satellite Systems Agency (also GSA) in 2010, and established in its current form on May 12, 2021. EUSPA is a separate entity from the European Space Agency (ESA), although the two entities work together closely.
