Ulog airspeed sensor logging - Flight Review

I would like to take a look at the readings from my airspeed sensor.
I am using Flight Review and I see an entry for airspeed, however the graph shows Airspeed estimated. Does this use the airspeed sensor data? If so how is the airspeed estimation done?

I would like to see the actual readings from the sensors, raw or scaled , but not estimated, is this possible?

As an aside is the ground speed estimated the GPS speed X Y components?



Flight Review shows the control_state.airspeed uORB topic, which is calculated by the estimator (ekf2 most likely, done here: https://github.com/PX4/Firmware/blob/master/src/modules/ekf2/ekf2_main.cpp#L768). This data comes from the airspeed topic, which is published in sensors module and uses the differential_pressure topic. So if you want to look at the raw data, look at differential_pressure, for example with FlightPlot.

Thanks, i’ll try that !
