Summary
This paper describes a five-year research and development programme (2020–2024) undertaken in Japan to advance next-generation high throughput satellite systems with enhanced capacity and multi-beam technology. The authors outline the integration of satellite systems with terrestrial 5G/Beyond 5G networks and present a satellite-terrestrial cooperation network simulator as a tool for identifying technical challenges and validating cooperative system algorithms. Results will be verified through on-orbit demonstration experiments using Engineering Test Satellite 9.
UK applicability
This paper is primarily of technical interest to satellite and telecommunications engineers and policy-makers involved in spectrum regulation and satellite infrastructure planning. The findings on satellite-terrestrial cooperation may have limited direct applicability to UK farming systems, soil health, or food production unless such satellite systems are subsequently applied to precision agriculture or rural broadband connectivity.
Key measures
Not applicable — this is a systems development and simulation study, not an empirical measurement study
Outcomes reported
The paper presents the conceptual framework and research outline for developing next-generation high throughput satellite (HTS) systems with improved capacity, flexibilisation, and digitalisation. It introduces a satellite-terrestrial cooperation network simulator designed to identify potential technical issues and verify algorithms for integrated satellite-5G/Beyond 5G systems.
