Re: [Paparazzi-devel] Airspeed message.

[Gautier Hattenberger]

Hi Helge,

This AIRSPEED message is older than the AIR_DATA system and it is a bit messy. As you said, you can get meaningful data from it if you add the flag USE_AIRSPEED, but this may have some side effects on the control loops, as some of them will start to use the airspeed data for control. So you should check that it will not change the flight behavior in your case.

Hi again,

Well, as far as I can see I get the AIRSPEED message from autopilot.c.

I was trying to narrow down the number of messages.

I think I will keep it in the telemetry file for future use of USE_AIRSPEED.

Hi,

I get much use of the air_data.xml module and AIR_DATA message to get pressure, temperature, altitude amsl and airspeed from my two barometer setup. Also the qnh calculation seems to work very well.

Now there is a message named AIRSPEED (#54 in Messages.xml), that is listed in default_fixedwing_imu.xml. It gives no data in my setup.

I am not sure where it is supposed to get its data from, and would like to remove it from the telemetry file. Could someone please give some informatiom about this message?

Thanks,

Helge.
