Orbital Lasers Co., Ltd. was established in January 2024 to commercialize space-based laser technologies developed through collaborative research between SKY Perfect JSAT and RIKEN. This presentation focuses on the simulation results of detumbling the upper stage of an H2A rocket body using a satellite equipped with a space-based pulsed laser system. When the pulsed laser irradiates the surface of space debris, plasma is generated, producing thrusting force. This thrusting force enables remote control of the target's attitude and can decelerate the debris, facilitating its de-orbit. This simulation focused on attitude control, specifically targeting the H2A upper stage with a rotational state. The results demonstrated that the H2A upper stage could be controlled even with laser pointing errors to achieve a gravity gradient stabilization state. This laser system can also be integrated into other contact-based active debris removal (ADR) satellites and enhance their adaptability to debris in a rotational state.
