Re: [Paparazzi-devel] MAGnetometer with INT_QUAT and EULER

[Felix Ruess]

Hi Eduardo,

Well, today i make some tests with magnetometer and i see some strange behavior.

When i using INT_CMPL_EULER the ROTORCRAFT_FP PSI show the correct MAGNETIC heading.

Correct would be true heading, not magnetic heading....

See IMU_MAG_OFFSET in http://paparazzi.enac.fr/wiki/Subsystem/ahrs#Complementary_Euler_.28fixed_point.29

 

When i using INT_CMPL_QUAT the PSI show another value.

im my specifiv case it show +16 deg.
its geomagnetic offset of my city (Porto Alegre / Brasil)

Its correct ?

Sounds like it shows you the true heading, so yes.

Cheers, Felix
