Abstract The Rosetta spacecraft reached the vicinity of the comet 67P/Churyumov–Gerasimenko in 2014 and released the lander Philae for an in-situ analysis through 10 scientific instruments. The analysis of the lander RF link telemetry reveals major information on the lander orientation and its near environment during the 50-h mission on the comet. The Philae waking-up in April 2015 led to new RF contacts whose analysis gives among others assumptions on the RF equipment status, even if further and deeper investigation will be necessary.

    Highlights Extensive analysis of the RF telemetry from the inter-satellite link. Whole mission events schedule retrieved in the received power indicator analysis. Multipath model to fit interference pattern observed during operations.
