I'm analysing my flights logs a bit deeper and I have a bunch of questions:
- GPS sampling: it seems to me, looking at the GPS time, that the sampling is not 10Hz but 5Hz. This is not a problem, just it is good to know
- In the log.pde file, there are 7 fields for attitude, while in the logs there are 9 numbers! Where do they come from? The same kind of issue apply for other measures.
- The units do not correspond to what indicated here. Is there an updated page for that?
Update: I managed to get 50Hz logs on everything. Here is a nice plot showing how motor control is working at very high frequency! I wonder if I have a vibration problem on the APM, those gyro readings are quite noisy...
