The eighth in the series of events organized by IAF Astrodynamics Committee aiming to join specialists in satellite constellation and formation flying will be held in Delft, The Netherlands, at the Faculty of Aerospace Engineering of the Delft University of Technology. Previous workshops have been held in Toulouse, France (1997), Haïfa, Israel (2001), Pisa, Italy (2003), Sao Jose dos Campos, Brazil (2005), Evpatoria, Ukraine (2008), Taipei, Taiwan (2010), and Lisbon, Portugal 2013 The 8th International Workshop on Satellite Constellations and Formation Flying provides continuity on key topics with previous IWSCFF workshops, but embraces crucial elements on the topic of the workshop, such as applications and enabling technologies. The growth of satellite constellations over the last years and the continuous increase of interest in formation flying missions are undoubtedly the most important and most exciting developments in commercial, institutional and scientific satellite services. Satellite communication services (based on GEO and LEO constellations), satellite monitoring and satellite navigation services are currently the main drivers of satellite applications. The unique and novel characteristics of these satellite systems have not only rejuvenated satellite system design but have also brought new life to classical flight dynamics disciplines like orbital mechanics, attitude control, guidance and navigation, etc. They have also triggered innovative ideas in the design and optimization domains (e.g., inclusion of economic considerations in addition to technical performance and operational availability).
