[Paparazzi-devel] Paparazzi EKF- and compelmentary- filter

[Prof. Dr.-Ing. Heinrich Warmers]

Hello,
we made same experiments with a EKF based  on the rotomotion solution in 
combination with the tiny13 and a low cost analogue IMU from sparkefun.
By the test i saw that the software is not  possible to  deal with  
pitch  angeles over  90°. So  to fly a looping is impossible.
If  90° arrives it is  impossible to get the correct angeles by the g 
force since static  z acceleration is zero.
If the pitch angels is more than  120°  the roll angeles rotate fast. 
What is about the  paparazzi  booz ekf and complementary filter. Can 
they deal  all angeles ? 
In the video from 2006  i saw only small  angeles.

Cheers

Heinrich
