[Paparazzi-devel] Airspeed and Navegation Tuning

Dear all,



Yesterday we achieved a completely autonomous flight using a Telemaster RC (with a 61 OS engine) where we have been testing the Paparazzi. Please find the log files attached. I also wanna thank you all for the help you have been providing us along the way.


After analyzing our results we notice that there are still some things that need to be done, for example:


- If you plot a graph of our airspeed setpoint, groundspeed and airspeed you can see that we have a lot of oscillations. We are using an Eagle Tree airspeed sensor. Is it possible to obtain a behavior like the one you show in the wiki (http://paparazzi.enac.fr/wiki/File:09_10_04_17_50_27_as1.png) using the eagle tree sensor? According to us, the sensor is not taking enough measurements in time and this doesn't allow good throttle adjustments.


- As you can see when you replay our log file, our navigation is not very accurate yet. How can we improve this?


Best Regards,
