"If orbit interpolation on large samples is needed, using the Ephemeris class is a better way [...] The Ephemeris class automatically handles selection of a neighboring sub-sample with a predefined number of point from a large global sample in a thread-safe way" https://www.orekit.org/static/apidocs/org/orekit/propagation/analytical/Ephemeris.html
