The Astropy Project: Sustaining and Growing a Community-oriented Open-source Project and the Latest Major Release (v5.0) of the Core Package
The Astropy Collaboration, Adrian M. Price-Whelan, Pey Lian Lim +133
The Astropy Project supports and fosters the development of open-source and openly-developed Python packages that provide commonly needed functionality to the astronomical communit…
Bayesian Shape Reconstruction and Optimal Guidance for Autonomous Landing on Asteroids
Shankar Kulumani, Taeyoung Lee
Construction of the precise shape of an asteroid is critical for spacecraft operations as the gravitational potential is determined by spatial mass distribution. The typical approa…
Constrained Geometric Attitude Control on SO(3)
Shankar Kulumani, Taeyoung Lee
This paper presents a new geometric adaptive control system with state inequality constraints for the attitude dynamics of a rigid body. The control system is designed such that th…
Geometric Control for Autonomous Landing on Asteroid Itokawa using Visual Localization
Shankar Kulumani, Kuya Takami, Taeyoung Lee
This paper considers the coupled orbit and attitude dynamics of a dumbbell spacecraft around an asteroid. Geometric methods are used to derive the coupled equations of motion, defi…
Low-Thrust Trajectory Design Using Reachability Sets near Asteroid 4769 Castalia
Shankar Kulumani, Taeyoung Lee
We present a computational approach for the design of continuous low thrust transfers around an asteroid. These transfers are computed through the use of a reachability set generat…
Geometric Adaptive Control of Attitude Dynamics on SO(3) with State Inequality Constraints
Shankar Kulumani, Christopher Poole, Taeyoung Lee
This paper presents a new geometric adaptive control system with state inequality constraints for the attitude dynamics of a rigid body. The control system is designed such that th…
