摘要

It is certainly evident that there is a wide breadth of existing research on relative motion dynamics present in the literature. This survey has sought to capture relevant features of a large subset of this literature by assessing the choice of relative motion state parameterization, derivation methodology, fundamental assumptions on reference orbit eccentricity and interspacecraft separation, and the ability to incorporate perturbations into analytical solutions. As opposed to treating the models as independent of one another, it is shown that a proper consideration of several methods for interrepresentation mapping merges the benefits of multiple approaches, leading to a more complete understanding of the relative motion dynamics. Furthermore, the results of a simulation-based comparative assessment quantify several key features of the considered dynamics models. First, in all cases, the use of orbital element-based models enables a more effective linearization of the relative motion for larger ranges of validity and improved performance in environments with large differential disturbance accelerations because the inclusion of relevant secular perturbation effects is simpler. Second, it is clear that neglecting reference orbit eccentricity can result in significant propagation error, even if relevant perturbations such as J_2 are modeled. Finally, even though a majority of the evaluated models consider at least the dominant J_2 perturbation effect to some degree, there is a strong motivation for further inclusion of other relevant perturbations into closed-form dynamics models.
