| Outline of Final Research Achievements |
In this research, a prototype model of attitude determination unit with omni-directional camera for nanosatellites and cubesats was developed and evaluated in ground environment. The model is consist of an imaging sensor and a FPGA board. Single imaging sensor can observe the shape of Earth, Sun, and Moon, then the image can be processed in satellite onboard unit. Three-axis attitude determination can be achieved both in daytime and eclipse phases. The target precision is less than 0.1 degrees, which is equivalent to low-end star sensors. Nanosatellites have limited resources in mass, volume, and power. The new sensor can be advanced technology by solving these restrictions.

| Academic Significance and Societal Importance of the Research Achievements |
ナノサットおよびマイクロサットの開発と軌道投入は、世界中で爆発的に急増している。衛星にとって姿勢決定・制御機能は、撮像センサを目的の方向に向けるために重要である。スターセンサは体積的リソースを必要とするため、代替となる確度0.1度程度の性能を有する姿勢センサは需要が高い。本分野では、価格が安くて小型・先進機能を持つ最新の地上製品を宇宙活用する例が多い。宇宙用途に特化する部分は、FPGAやCPUによるソフトウェアで補完可能であり、短時間・低コストに問題を解決できる。
