A new method for refining the physical and behavioural characteristics of near-earth orbiting objects is being developed. The method can be thought of as orbit determination using more object characteristic parameters and with geophysical, atmospheric and third-body models of greater fidelity than are typically used. The method is similar to cell-based engineering analyses in that it is solved through linear algebraic methods. In this first PhD annual report, the progress on developing the method will be presented. Convergence to a theoretically valid solution has been achieved but the solutions are not unique and vary with infinitesimal changes to the initial estimates; a consequence of a non-linear system of equations with limited diversity. Current work on characterising and improving equation diversity as well as the opportunity to incorporate additional analytic features will be presented. Collaboration opportunities for the next twelve months will also be discussed. |
