Objectives
The NON-GEO 5GCBH technology project explores and de-risks 3 major technology domains related to multi-orbit ground segment Satcom systems:
-
Seamless satellite handover mechanisms in constellations
-
Flexible Payload interaction with ground segment
-
Service orchestrated interaction with terrestrial networks
The project objective is to advance the TRL of these key technologies from TRL2-3 to TRL level 5 through focused Proof of Concepts and as such prepare for full multi-orbit ground segment system development.
Challenges
The key challenge is to ensure that all the related technologies and modules interact dynamically in a seamless and reliable manner; For the Seamless satellite handover mechanisms in constellations and Flexible Payload interaction with ground segment the interfacing and time synchronisation with the satellite segment is key, for the Service orchestrated interaction with terrestrial networks, the interfacing and related standardisation(MEF) with terrestrial networks is key. All this as opposed to the more traditional “configuration through the management plane” approach in legacy VSAT systems.
System Architecture
The high level system architecture is presented in the figure above. The three technologies address differents areas in the system architecture
-
Seamless satellite handover mechanisms in constellations. This is within the ground segment control plane part involving the Hub and terminal side (MBB-BBM)
-
Flexible Payload interaction with ground segment. This is communication interface between the flexible payload and the Central Hub part
-
Service orchestrated interaction with terrestrial networks. This interaction is located in the central NMS part of the ground segment system (MEF)
Plan
At PDR, the Top level architecture of the three technology domains were delivered and presented.
At the Mid Term Review the developed technologies were completed and test plans provided. The Milestone was successfully held in September 2021.
At the Final Review the test campaign was completed. Test reports and updated Top Level Architectures were provided.
The Technology project has been finalized in December 2021.
Current Status
The project has successfully been finalized in December 2021.
