Hi,
Same for me : flying around 650 hectares, pixhawk took 1255 images and I have only 1003 events !
Even if I get a nice result in ppk, watch picture below. Configuration with GPS 14Hz.
We clearly see where it’s missing (green = reach (pos file) , red = pixhawk gps from log : gpx file)
Could I send you log (ubx = 80mo) ?
