GAUSS: Galileo-EGNOS as an Asset for UTM Safety and Security. H2020 project of the European Commission. U-space is defined as a set of procedures and services to support safe, efficient, and secure access to airspace for UAS. GAUSS aims to develop a safety UTM developing in-flight services for integrating rotary and fix-wing UAS flying in the U-space. Part of the integration with MAGNA was published. Explicative videos of experiments here.
