Project Description

This project addresses the stability of motion around minor bodies (asteroids or comets) considering uncertainties of both the spacecraft’s state and the model parameters e.g. the mass of the asteroid, rotation errors, etc., with algebraic propagation methods.

Explorations of minor bodies have attracted lots of attentions, in terms of their scientific and resource values, and also human safety concerns. One challenge for the mission design is to identify the stable motion of spacecraft (s/c) in the highly perturbed and uncertain dynamical environment. To meet the practical mission requirements, this project addresses the stability of spacecraft’s motion around minor bodies (asteroids or comets) considering uncertainties of the initial state of the spacecraft and also the uncertainties of the model parameters e.g. the mass of the asteroid, rotation errors, etc. The algebraic methods are applied to propagate both the trajectory and the uncertainties. How this practical stability region will contribute to the robustness mission design is explored. A software tool will be developed for systematic analysis.

Proposed Start Date: 1 April 2020

Funding Notes

Applicants should preferably hold, or obtain a first class honours or equivalent, preferably in mechanical engineering, or applied mathematics

Programming skills in matlab or python c++ or fortran, etc

Funding is to be confirmed between the University of Strathclyde and Europe Space Agency early in 2020?
