Hi @robin-shaun,
-
FlightReview shows the vehicle_angular_velocity topic (flight_review/configured_plots.py at 4a2c27821bb1455bd3d7de514ec4da79d7760c03 · PX4/flight_review · GitHub).
-
vehicle_angular_velocity is published here and the data is a calibrated version of
sensor_control -
sensor_controlcomes from PX4Gyroscope.cpp and contains the filtered gyro values
Conclusion, FlightReview shows the filtered gyro data.
Filtering the data again reduces the noise, yes, because you apply more filtering.
If you are interested of seeing the raw gyro values, you have to look for sensor_combined/gyro_rad.
Here is an example of data showing the difference between the raw data (sensor_combined) and the data going to the controller (vehicle_angular_velocity):
Your drone can fly because you don’t need crazy gains to make a quad fly and the bandwidth of the controller can then be really low and not affected by the noise.
I hope this helped to clarify.
