About

Koh Kamachi is a space systems engineer and researcher affiliated with the Space Robotics Laboratory (SRL) at Tohoku University, specializing in microsatellite development, attitude and orbit control systems, and space mission operations. His work centers on the ambitious ALE-1 and ALE-2 microsatellite projects — a pioneering collaboration between Tohoku University and ALE Co., Ltd. aimed at generating artificial meteor showers for both scientific study and public engagement. Kamachi's most significant contributions span the full lifecycle of microsatellite engineering. He has advanced thruster control approaches for autonomous orbit and attitude management, developed innovative double fail-safe attitude control architectures verified through hardware-in-the-loop simulation, and established robust ground evaluation and operational training systems. His work also extends to structural design and verification under strict safety and compressed development timelines, as well as mission control systems capable of managing the precise, safety-critical ejection of meteor particles from orbit. With a cumulative citation count of approximately 31 across his key publications, Kamachi's research has made a meaningful impact in the small satellite community. His work exemplifies how cutting-edge engineering can enable novel, visually spectacular scientific missions that bridge aerospace research and public outreach.
