The aim of the present activity is to investigate novel Non-regular Multibeam Coverage Payloads architectures for future multibeam satellites with Non-Uniform Traffic request over the coverage and to develop dedicated design tools. Non-regular Multibeam Coverage Payloads offer substantial advantages to maintain an affordable payload complexity while offering substantial advantages in increasing the offered satellite capacity for non-uniformly distributed traffic request (preliminary assessment showed a potential increase of 50% of the offered capacity). The study shall investigate novel Non-regular Multibeam Coverage Payloads architectures for future multibeam satellites with Non-Uniform Traffic request over the coverage and to develop dedicated design tools. Expected outcomes include: – definition of optimal coverage strategies and development of dedicated tools (with a transfer of ESA know-how on relevant coverage and frequency plan optimization techniques – identification and trade-off of payload/antenna architecture – preliminary design of a future Non-regular Multibeam Coverage Payload for Non-Uniform Traffic – main performances and budget – cost analysis – identification of technology gaps and technological roadmap
