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…
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…
