  A hybrid orbit propagator based on the analytical integration of the Kepler
problem is designed to determine the future position and velocity of any
orbiter, usually an artificial satellite or space debris fragment, in two
steps: an initial approximation generated by means of an integration method,
followed by a forecast of its error, determined by a prediction technique that
models and reproduces the missing dynamics. In this study we analyze the effect
of slightly changing the initial conditions for which a hybrid propagator was
developed. We explore the possibility of generating a new hybrid propagator
from others previously developed for nearby initial conditions. We find that
the interpolation of the parameters of the prediction technique, which in this
case is an additive Holt-Winters method, yields similarly accurate results to a
non-interpolated hybrid propagator when modeling the J2 effect in the main
problem propagation.
