Federation of Satellite Systems for Integrated Satellite-Terrestrial Networks: the 5G-HUB Project

Satellite communication networks have long served as a vital connectivity backbone across Europe, particularly in remote and strategic areas. To enhance the efficiency of satellite operators in managing connectivity demands, the 5G-HUB project (within the Horizon Europe framework) aims to advance the EU's flagship GOVSATCOM initiative by developing a flexible and interoperable network management interface. This interface will link the GOVSATCOM-HUB (G-HUB) with resource providers deploying 5G core networks and microservice-based infrastructure. The project will validate G-HUB functions through three trials involving an interoperable 5 G NonTerrestrial Network (NTN) terminal operating in Ku and X bands. These trials will assess seamless resource allocation, Quality of Service (QoS) provision, and transparent traffic steering between satellite and terrestrial networks, especially in critical scenarios such as emergency and maritime operations. Additionally, the project will explore interoperability across multiple satellite network operators to support robust and resilient governmental communications.
