Orbit and attitude refinement of a spinning satellite using landmark data
Abstract
A methodology is presented for the orbit and attitude refinement of a spinning satellite using landmarks extracted from the imagery obtained from its sensors. The search strategy comprises both random and deterministic searches whose order of deployment is chosen in such a way as to exploit the relative inherent advantages of both types of methods. Findings of extensive simulation exercises are presented that include several trend analyses like radius of convergence, effect of observation errors and data span. The feasibility of the proposed methodology is demonstrated by application to actual data of the Indian satellite RSD2 which carried a 'Smart' sensor onboard.
