[Paparazzi-devel] Lisa/M v2 +Aspirin IMU loss

[Balazs GATI]

Hi all,

yesterday we experienced the total loss of attitude calculation of a 
Lisa/M v2 (quadshot) with Aspirin IMU in open air. (I mean the 
artificial horizon went wild after we left the building.) Fortunately we 
didnt want to fly, but test the GPS. Finally we could identify the 
problem: the IMU worked only if we provided some kind of physical cover 
to the module. Steel and aluminium sheet, thick paper worked. (80g/m2 
copy paper and pure hand don't.) We could explain the phenomen with the 
increased sun activity or with some strange failure in grounding.

Have you got similar experience in the last few days?

Regards,
 Balazs
