The Space ICT Promotion Initiative Forum - Understanding the future of the space business  

New Wave of Space Business and Hopes on Space ICT Promotion Initiative Forum (SPIF)
Space business is now experiencing a huge departure such that main players have changed from government to private sectors including ventures, and that many small satellite constellation businesses have been appearing. Varied companies are entering space business from other fields, where movements to create new values are occurring with space as an “Enabler.” This seminar will explain such new movements of space business and their future vision, and also introduce a community “Space ICT Promotion Initiative Forum (SPIF)” and our hopes on this community.

A Study on Millimeter Wave (mmW) Band High Gain Lens Antenna for Non-Terrestrial Network (NTN)
Beyond 5G/6G is expected to extend the communication area not only to the ground but also to the sea, air, remote areas, and space, therefore, research and development for the realization of non-terrestrial network (NTN) is actively conducted. However, NTN requires high-gain millimeter-wave antennas with high propagation loss. We focus on lens antennas as high-gain antennas and present the results of our investigations.

Development of optical ground stations for the testbed in NICT
Laser communication has been studied and developed in recent years as a promising means to increase the speed of communication between satellite and optical ground station. Moreover, the laser communication should be optimum for the cryptographic communication due to its high directivity, and it is considered to be a very important means of communication to ensure communication with high level of security, for which demand is expected to increase in the future. NICT is currently developing optical ground stations that can be used as a testbed. We are now constructing a 2-m aperture optical ground station in Kashima, 40-cm optical ground stations installed in three locations: Koganei, Kajima and Kanbe, a transportable optical ground station, and a small portable ground station. We introduces the details of these optical ground stations and their use cases in this presentation.
