Suboptimal Formation Reconfiguration of Satellites Under Input Directional Constraints
Yasuhiro Yoshimura
Proximity operations of satellites such as formation flying and on-orbit servicing offer more advanced missions than missions achieved by a single satellite. In a practical situati…
Optimization of Fault-Tolerant Thruster Configurations for Satellite Control
Yasuhiro Yoshimura, Hirohisa Kojima
The fault tolerance of spacecraft actuators significantly affects the reliability of satellites and the likelihood of successful missions. To enhance the fault tolerance of the act…
Formation Keeping Control for Deorbiting an Uncooperative Satellite by Laser Ablation
Shun Isobe, Yasuhiro Yoshimura, Toshiya Hanada +2
This paper proposes the formation keeping control law for deorbiting debris by a laser ablation. Laser ablation is vital technology for contactless active debris removal, where a c…
Assessing Collision Probability in Low-Thrust Deorbit
Shuta Fukii, Daisuke Sakai, Yasuhiro Yoshimura +4
End-of-life support of satellites is necessary to improve post-mission-disposal compliance rates for maintaining space environment. Deorbit mission with low thrust, e.g. a laser, i…
Adaptive Relative Orbit Control Considering Laser Ablation Uncertainty
Shun Isobe, Yasuhiro Yoshimura, Toshiya Hanada +2
This study proposes a relative orbit control law for laser debris removal missions considering the uncertainties of laser ablation and atmospheric drag. A removal spacecraft irradi…
Attitude Estimation from Photometric Data using Gaussian Process Regression
Ryui Hara, Yasuhiro Yoshimura, Toshiya Hanada
The rapid growth of resident space objects in Earth's orbit has intensified the need for advanced space situational awareness and space domain awareness to manage satellite traffic…
Improving Observability of Relative Orbit Estimation Using Bearing Measurements and Light Curves
Yasuhiro Yoshimura, Toshiya Hanada
Relative orbit estimation using optical observations is a key technology for on-orbit servicing missions. In the far-range phase, the target appears as an unresolved point source,…
Adaptive Attitude Estimation for Multiple-Surface Object Using Light Curve Glints
Yasuhiro Yoshimura, Toshiya Hanada
Light curve inversion enables the estimation of orbit, attitude, optical properties, and shape of space objects. Because a light curve is the temporal evolution of a scalar apparen…
Data-Driven Prediction of Chaotic Transition in Periapsis Poincaré Maps
Shanshan Pan, Taiki Urashi, Mai Bando +3
Chaotic trajectories in multi-body dynamical systems play a crucial role in designing low-energy trajectories in astrodynamics. However, predicting these trajectories is inherently…
Model Predictive Approach for Detumbling an Underactuated Satellite
Kota Kondo, Yasuhiro Yoshimura, Mai Bando +2
This research proposes an innovative approach to detumble satellites' triple-axis angular velocities with only one single-axis magnetic torquer. Since magnetic torque is generated…
Nonlinear Model Predictive Detumbling of Small Satellites with a Single-axis Magnetorquer
Kota Kondo, Ilya Kolmanovsky, Yasuhiro Yoshimura +3
Various actuators are used in spacecraft to achieve attitude stabilization, including thrusters, momentum wheels, and control moment gyros. Small satellites, however, have stringen…
Pulse Width Modulation Method Applied to Nonlinear Model Predictive Control on an Under-actuated Small Satellite
Kota Kondo, Yasuhiro Yoshimura, Shiji Nagasaki +1
Among various satellite actuators, magnetic torquers have been widely equipped for stabilization and attitude control of small satellites. Although magnetorquers are generally used…
