    The solution to this problem caused by unsynchronized clocks is obvious - configure Perseverance to keeps its comm. system continuously turned on for a few hours!

    That's what they did on May 5, 2022. A few hours later, Percy received Ingenuity's call, exchanged status info. and promptly set Ingenuity's clock to the correct value.

    This is what JPL must have done today - "instructing Perseverance to perform long-duration listening sessions for Ingenuity’s signal."

    I doubt they use NTP 🕰️
