| Outline of Final Research Achievements |
We have successfully developed a Software Defined Radio (SDR) module that can be integrated into a CubeSat, which was our goal in this study. Additionally, we have developed a frame edge antenna for CubeSats that does not require a 1U-sized deployment and conducted performance evaluations on it.
The flexibility of the developed SDR module is considered world-class in both software and hardware aspects. With its small size, low power consumption, and the ability to control transmission and reception using commercially available microcontroller boards, the SDR module can be directly integrated as a CubeSat operational control radio device, meeting the requirements in terms of functionality and performance.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で開発したSDRモジュールは省電力であるとともに、変調するためのI/Q信号を直接入力可能であることが特徴であり、拡張性が高く無線における変復調の実験が手軽に可能である。CubeSatの運用管制で一般的に使用される435MHzアマチュア無線帯をカバーしている。
この無線モジュールを搭載したCubeSatの打上げと運用管制に成功した時には、産業界にも大きく貢献できる。
本研究で得られた成果はCubeSatでの利用ばかりではなく、手軽に無線通信実験が可能であるSDRモジュールの開発に成功した点も大きいと言える。
