Thank you for your concern.I tried the define:
<configure name="USE_MAGNETOMETER" value="FALSE"/>
And it failed.
But the problem gone since I update the code from v5.6 to v5.8.It seems that it is a bug about the attitude estimation of v5.6.
Thank you!

it should work fine with the defaults: fixedwing uses GPS course by default and disables the mag...
If you make double sure and disable the mag, use configure instead of define:

<configure name="USE_MAGNETOMETER" value="FALSE"/>

You can also check all the added flags in var/aircrafts/<aircraft_name>/ap_srcs.list

Hope that helps,

Or if the algorithm still has issuse about the "BODY_TO _IMU"?
since I rotate the lisa -90 degree from the airframe,I set the  "BODY_TO IMU"
like this:  
    <define name="BODY_TO_IMU_PHI"   value="0." unit="deg"/>
    <define name="BODY_TO_IMU_THETA" value="0." unit="deg"/>
    <define name="BODY_TO_IMU_PSI"   value="270." unit="deg"/>

You can try double checking the mag is disabled by turning off the gyro and
seeing if the magnetometer updates the direction. set AHRS_MAG_OMEGA to a
higher value.

As well if you have the latest release of paparazzi you can set this flag to
disable the onboard magnetometer.
<define name="ASPIRIN_2_DISABLE_MAG value="TRUE"/>
