Resum

In this paper, we present a methodology to perform new families of hybrid real-time and analytical orbit propagators which combine a simplified analytical orbit propagator with time series models. When time series analysis is a useful statistical prediction tool, which, from the studies of past observations of this same series, a model can be built so as to make future predictions. This combination allows an increase in accuracy without significant loss in efficiency of the new propagators as well as modelling those perturbations that have not been considered in the analytical theory. The above features make these types of propagators good candidates as part of an economic onboard orbit determination system.
