  • Hi, I’ve just received your IMU and I’m going to test it.
    I studied carefully your AHRS code and I’m very impressed about simplicity and accurary (theorically).
    I’ve a lot of question to ask, but now I start with the first and second only:-)
    Q#1: Have you try to use same accelerometer output for twice integration to estimate position ?
    Q#2: Do you think it is necessary to use a second kalman filter matrix to correct accelerometer output errors?
    My goal is to upgrade your IMU/AHRS in a complete INS.
    Thank in advance.

No public wish lists :(
