Hybrid analytical-statistical models

Abstract

To carry out new families of hybrid analytical orbit propagator programs a new methodology is presented. These families combine a simplified analytical orbit propagator with statistical time series models. In fact, this approach allows the increase of accuracy without loss of efficiency in the hybrid propagators as well as integrating the effects of those perturbations that have not been taken into account in the development of the analytical theory. These types of propagators can become, among other uses, good candidates for forming part of an economic onboard orbit determination system. © 2011 Springer-Verlag.
