Effects Analysis of Frozen Conditions for Spacecraft Relative Motion Dynamics

The purpose of this rersearch is to analyze the effective application of particular earth orbits in dynamical modeling of relative motion problem between two spacecraft. One challenge in implementing these motions is maintaining the relations as it experiences orbital perturbations (zonal harmonics J2 and J3), most notably due to the Earth’s oblateness. Certain aspects of the orbital geometry c...

Coordinated Manipulator/spacecraft Motion Control for Space Robotic Systems

This paper studies the coordinated control of space manipulators and their spacecraft. The dynamics of freeflying space robotic systems are written compactly as functions of the system barycentric vectors. A control technique is developed that includes requirements on a spacecraft’s position and orientation as well as on its manipulator. A Transposed-Jacobian type controller with inertial feedb...

Model Based Visual Relative Motion Estimation and Control of a Spacecraft Utilizing Computer Graphics

An algorithm is developed for estimating the motion (relative attitude and relative position) of large pieces of space debris, such as failed satellite. The algorithm is designed to be used by a debris removal space robot which would perform six degreeof-freedom motion control (control its position and attitude simultaneously). The information required as feedback signals for such a controller ...

Maximum Correntropy Unscented Kalman Filter for Spacecraft Relative State Estimation

A new algorithm called maximum correntropy unscented Kalman filter (MCUKF) is proposed and applied to relative state estimation in space communication networks. As is well known, the unscented Kalman filter (UKF) provides an efficient tool to solve the non-linear state estimate problem. However, the UKF usually plays well in Gaussian noises. Its performance may deteriorate substantially in the ...

High Accuracy Relative Motion of Spacecraft Using Linearized Time-Varying J2-Perturbed Terms

This paper presents a set of linearized equations was derived for the motion, relative to an elliptical reference orbit, of an object influenced by J2 perturbation terms. Approximate solution for simulations was used to compare these equations and the linearized keplerian equations to the exact equations. The inclusion of the linearized perturbations in the derived equations increased the high ...
