Setting up GSSAC
• Creation of a national capability to provide and assess the space situation
• The central contact point of Federal Government regarding Space Situational Awareness towards third parties is GSSAC
• Joint realization (of the project) “GSSAC" between German Air Force and DLR Space Administration
• Establishment of national competence for recording and assessing the space situation
• Joint efforts to ensure the security and protection of space infrastructure
Concept for a Space Surveillance System (2008)
Strategy for Space of the Federal Government (2010)
Agreement between German Ministry of Defence (BMVg) & German Ministry for Economic Affairs and Energy (BMWi)
