Does QGC log the dives? Or some other software that can log the dives.
It would be a good option if the software does log the dives, like dive time, depth, temperature etc. So that way it would be manageable to monitor how many dives and depth the vehicle has.
Yes, both QGC and the autopilot itself log the dives. The QGC .tlog files are generally smaller and a bit more accessible, but the autopilot’s .bin logs include higher data frequency and some additional data.
There’s some more information about accessing and convenient ways of viewing and/or analysing them here
