Warning about the orbit constellation plots
The relative orbital constellation as such seems reasonably okay though. I think it models only using gravity (its software for modelling solar system object orbits after all) and not drag, hence the satellites get plotted at wrong positions in their orbits .
So be careful with the 3D plots I recently posted. The relative orbit orientations seem okay, but the absolute positions of the satellites not.
Note added 16/10: WinOrsa author Pasquale Tricarico today confirmed me that only gravity is modelled and not (yet) drag. This will hopefully be included in a future release. That would be cool, as the 3D graphic output of the software is great.
