Hi @petrus.hyvonen,
Yes, there’s also the AggregatedPVCoordinatesProvider introduced by Joseph Reed a year ago in 11.3 that would take either the propagators themselves or their generated ephemeris.
I think it’s a great idea!
@Vincent recently greatly improved interpolation features in Orekit and introduced the notion of OrbitBlender in the process.
I don’t think it is directly usable, but maybe we could introduce a PropagatorBlender
or a PVCoordinatesProviderBlender
?
