5GEOSiS
The ambition of 5GEOSiS is to support this evolution through the provision of a suitable hardware test-bed and initial trade-off studies.
In general, the biggest challenge for the project is that the concepts for space-based Joint Processing and Communication and Integrated Sensing and Communications are not yet very mature making it difficult to assess the benefit and value of sharing of parts (e.g. frequency up-/down-conversion) or all (including the antenna) of the RF Tx/Rx chain between 5G communications and RF sensing. Within this main challenge there is a clear issue regarding the limited (rather low) capacity of compute elements, and the critical aspect of interfacing with the peripheral elements.
Concerning the fundamental aspect of sharing resources, the project plans to use practices and solutions already proven in terrestrial networks.
The main benefit of 5GEOSiS is the support for the creation of a common platform, a server in space that can be repurposed.
Ultimately, 5GEOSiS provides a HW platform, a test-bed for experimenting and validating Joint Processing and Communication concepts and approaches – a server in space that can be dynamically repurposed. This is an entirely new area, certainly in the space environment, concerning satellite payloads.
