Yes satellite signal not great down there! The closest spot I can pop out for a quick test at the moment.
Anyway, I replaced the standoffs for the flight computer plate with some natural rubber isolators and have got the vibes down a bit more, pos hold did seem better. below is Vibe analysis and FFT. Top is with the plate mounted on plastic standoffs, bottom is on the rubber. Max vibes are down, though averages not much changed. FFT shows the ~180Hz peak down and 60-70Hz down a bit, but not by so much. Seems all good on the vibrations front to me now though…
