Thanks for the link Bryan, I didn’t know about the genesis of StaticTransform, which is one of the best recent addition in Orekit imho. What do you think @evan.ward ? Should we go on with your idea of KineticTransform? Ideally I would like to rework PVCoordinates because the fact that it can hide an acceleration is at best a nomenclature issue already raised here. But there’s no time to do it for Orekit 12 so I’m not sure what to do in the short term.
Cheers,
Romain.
