In the past decade, there has been significant progress in private space development, commonly referred to as NewSpace. One of the most notable advancements is the deployment of satellite constellations, with numerous small satellites being placed in low Earth orbit (LEO) to support communication and remote sensing applications. Looking ahead, it is anticipated that CPS (Cyber-Physical Systems) will be extended into space by leveraging artificial satellites as IoT devices or NTN communication platforms. To achieve this vision, we are conducting fundamental research on high-bandwidth communication satellites utilizing formation flying techniques. This presentation will introduce these emerging trends and highlight the related research activities.
