Thanks, Dr. Nil and LittleBear!
To make it clearer: I'm only placing my station in one system, so I'm not concerned with the coordinates being different in another system, which of course they are.
I was concerned with the coordinates of sun and planet relative to each other changing over time in the same system, because that would mean an object placed in a certain location in a coordinate system originating from the planet (like psm) would not be in the same place relative to the sun over time, which would be bad, because a station being very close to the sun (where I want to have it) would be eaten up by the sun at another time (which I don't want).
Now I did some testing, changing the time-string in my test pilot's log and starting my OXP in a couple of completely different times. And the result: As far as I can tell no matter at what game time I played, my station appeared always in the same place relative to the sun, just at that point where my ships altimeter over the sun turns from yellow to red (so, indeed very close to the sun, that's because in my storyline the station has lost its orbit due to an asteroid storm, and the player's task is to save it; success or failure to return to the station with some spare parts before it blows up will trigger different chains of events with different changes to the Ooniverse).
So for the question of positions of objects in a system I would conclude that the positions of planet and sun in a given system are fixed to each other throughout the game. (So in a given system the sun will always be e.g. at psm 0 0 900000 and the planet will always be at spm 0 0 900000)
