hello,
I am doing the calibration without Temperature, and i have done as the steps follows:
http://autoquad.org/wiki/wiki/configuri ... pensation/
but not all parameters have value when running the step5(sim3 -gyo -acc), The value start like this, and the parametes whose value is 0.00000000 will always be zero, what's wrong with my work? could anybody help me?

Do you have the "Using DIMU" checkbox enabled?

yes, i have enabled "Using DIMU"

I don't know how to post an map, i have enabled "Using DIMU" and i have paste the first 3 lines to the “all generated parameters” tab and hitting save, at first, i forgot to hit save, and those three parameters are zero too:DEFAULT_IMU_ACC_BIAS_X DEFAULT_IMU_ACC_BIAS_Y DEFAULT_IMU_ACC_BIAS_Z. Aftering hitting save, I run step5 again and then i got the phenomenon as i post above.

Pls post the log files beeing used. I will do a comparison run here.

See that Jussih :http://forum.autoquad.org/viewtopic.php?f=35&t=3769

Me too, i get the same problem

Alain

The ALGN (alignment) parameters are not currently being used or estimated.

Thanks for all your help,
JussiH, here is one of my dynamic log files, please help me to have a look on it if your have time, thanks a lot:

hello bn999,
What are the ALGN (alignment) parameters? Are they used in the parameter calculation and where should i check if they are right or not?
