Refresh Rates of AHRS Information

Hardware Pixhawk family
1

I would like to ask for the technical specs of the AHRS particularly the Sampling Rate of the following data:

  1. Pitch, roll, yaw
  2. Airspeed
2

Both of data are filtered outputs of asychronous sensors. What exactly do you mean, the “sampling rate” of a filter? Do you mean the update-rate, or the logging-rate?

In case you want the logging rate:

  1. Both the AHRS and the NavEKF log the aircraft’s orientation at 25Hz, as specified in ArduPlane.cpp (the frequency of Log_Write_Fast in the scheduler).

  2. The airspeed system is read, and logged, at 10Hz, as specified in ArduPlane.cpp (the frequency of read_airspeed in the scheduler)
