Abstract

A major cause of spacecraft orbital variation comes from natural perturbations, which, in close proximity of a body, are dominated by its non-spherical nature. For small bodies, such as asteroids, these effects can be considerable, given their uneven (and uncertain) mass distribution. We propose to use solar sail technology to reduce or eliminate the net effects of the irregular gravity field on the orbit. The Perturbation Relief (PR) method will be introduced which obtains a minimum effort optimal control law via the GPOPS II software. Success will be shown by taking a Poincar´e section and measuring the distance between the point through which each successive orbit passes. This distance will reduce to zero as the perturbation is nullified, resulting in a periodic orbit. The drift in Right Ascension of the Ascending Node (Ω) will also be verified. Minimisation of this will also indicate that the effects of the perturbation are minimised. Three test cases will be investigated at ellipsoidal representations of asteroids 3122 Florence, 101955 Bennu and a fictional Higher Eccentricity Body. The technique will later find application in a multiple asteroid rendezvous mission with a solar sail as the primary propulsion system.
