How to extract per-epoch satellite positions using PPP and precise ephemeris?

[LYM28]

Hello, I’m working with RTKLIB 2.4.2 and running PPP using SP3 precise ephemeris and CLK files. I would like to extract the ECEF or LLH position of each satellite at each epoch during PPP processing.

So far, I can get receiver positions from the .pos file, but I’d like to track satellite position changes across epochs.

Could you advise where in the code (pppos()?) I can intercept satellite coordinates and output them (e.g., via rtk->ssat[])?

Thank you very much!
