Re: [Paparazzi-devel] Apogee's attitude recovery

[Dylan Brunello]

Hi,

Are you sure it is not just the update rate of the graphics? If you open the plotting tool and messages tool you can drag and drop the roll and pitch angles (phi and theta) into the plotting window and see the values as the change with time. I think this will give you a better idea of the instantaneous values rather than using the PFD.

Cheers,
Dylan

Hi,

with questions like this please always try to be as specific as possible.

Which paparazzi_version are you running? What AHRS algorithm are you using? How is your IMU set up?

Best is to provide the airframe file you are using (or at least the relevant sections).

Cheers, Felx

Hi. I can't help you but I am interested to know how many degrees you mean by strenous and how many seconds you mean by slow?

Good luck

HI guys:
      Apogee's attitude is accurate. 
     but， The attitude is very slow recovery after strenuous exercise (pith and roll).
     What is the reason?
