Re: [Paparazzi-devel] DCM AHRS help

[Christophe De Wagter]

Dear Blake,

How did you calibrate your IMU? Did you look at the messages to see if your accelerometer and gyro's are looking correct (accelerometers should measure -9.81 m/s2).

Choosing another ahrs filter will give the same problems if your calibration is not good enough. 

You can also select "Raw Data" option in the GCS Ap-Telemetry-Mode (http://paparazzi.enac.fr/wiki/GCS#Settings)and look at the raw measurements and log them.

Hello,

I am having some issues with the DCM AHRS setup for the PPZUAV IMU.   The attitude value will not increase past + or - 10deg no matter how I hold the autopilot.  

It might be important to note that I have edited the PPZUAV setup to use a l3g4200 gyro instead of the itg3200.

Can someone advice me on how to configure the ahrs correctly?

As a side note, are there any other imu filtering options?

Thank you.
