Outline of Final Research Achievements

This research aims to develop a new orbit control method by studying the forces generated from interactions between low-earth orbit plasma and electromagnetic coils installed on satellites for attitude control. First, the research investigates plasma forces experimentally to clarify the mechanism of reactive forces, with a focus on the interaction between space plasma and onboard magnetic coils. Then, the lift force is also experimentally investigated. Through experiments and simulations, this research aims to elucidate the principles underlying the generation of reactive forces by plasma.

Academic Significance and Societal Importance of the Research Achievements

最近、衛星の小型化と複数機化が急速に進み、複数機による新たな宇宙システムの構築と展開が喫緊の課題となっており、推進機の小型化が検討されている.本研究で扱った「電磁コイルにより力を生む」ことにより新たな軌道制御手法が構築できれば、これまで軌道制御が難しかったより小型の衛星についても軌道制御により編隊飛行やコンステレーションに応用することができ、多地点同時観測や継続的観測を長期間可能とする新たな宇宙システムへの展開が期待できる。
