Preliminary simulation for light curves of rocket body in LEO

Orbital debris has become an inevitable problem for the future space exploration, and spacecraft is suggested to remove orbital debris. To fulfill this mission, you need to know target's attitude motion when installing a mitigation-related device. To support, we developed a simulator of orbit, attitude, and light curve to see how an object behaves. This paper presents a process to simulate virtual rocket body's observation in LEO assuming an existing telescope in Kyushu University, and to estimate the triaxial ratio, the spin axis, and the shape model. The real observation is supposed to be held in the near future.
