Non-Gaussian Distribution Steering in Nonlinear Dynamics with Conjugate Unscented Transformation
Daniel C. Qi, Kenshiro Oguri, Puneet Singla +1
In highly nonlinear systems such as the ones commonly found in astrodynamics, Gaussian distributions generally evolve into non-Gaussian distributions. This paper introduces a metho…
Encrypted Computation of Collision Probability for Secure Satellite Conjunction Analysis
Jihoon Suh, Michael Hibbard, Kaoru Teranishi +3
The computation of collision probability () is crucial for space environmentalism and sustainability by providing decision-making knowledge that can prevent collisio…
Semi-global Exponential Stability for Dual Quaternion Based Rigid-Body Tracking Control
Vrushabh Zinage, S P Arjun Ram, Maruthi R. Akella +1
Semi-Global Exponential Stability (SGES) is proved for the combined attitude and position rigid body motion tracking problem, which was previously only known to be asymptotically s…
Precision Attitude Stabilization with Intermittent External Torque
S. P. Arjun Ram, Maruthi R Akella
The attitude stabilization of a micro-satellite employing a variable-amplitude cold gas thruster which reflects as a time varying gain on the control input is considered. Existing…
Feedback Strategies for Hypersonic Pursuit of a Ground Evader
Yoonjae Lee, Efstathios Bakolas, Maruthi R. Akella
In this paper, we present a game-theoretic feedback terminal guidance law for an autonomous, unpowered hypersonic pursuit vehicle that seeks to intercept an evading ground target w…
Riemannian Trust-Region based Adaptive Kalman filter with unknown noise Covariance matrices
Rahul Moghe, Maruthi R. Akella, Renato Zanetti
The problem of adaptive Kalman filtering for a discrete observable linear time-varying system with unknown noise covariance matrices is addressed in this paper. The measurement dif…
Real-Time, Flight-Ready, Non-Cooperative Spacecraft Pose Estimation Using Monocular Imagery
Kevin Black, Shrivu Shankar, Daniel Fonseka +3
A key requirement for autonomous on-orbit proximity operations is the estimation of a target spacecraft's relative pose (position and orientation). It is desirable to employ monocu…
A Pipeline for Vision-Based On-Orbit Proximity Operations Using Deep Learning and Synthetic Imagery
Carson Schubert, Kevin Black, Daniel Fonseka +5
Deep learning has become the gold standard for image processing over the past decade. Simultaneously, we have seen growing interest in orbital activities such as satellite servicin…
Stabilizing Controllers for Multi-Input, Singular Control Gain Systems
Srikant Sukumar, Maruthi R. Akella
This paper proposes a new methodology for design of a stabilizing control law for multi-input linear systems with time-varying, singular gains on the control. The results presented…
