Attitude estimate unstable #24

Open tobinfisher opened 10 years ago

While testing outside in cold weather, the attitude estimate (as indicated by the iPhone horizon display) would be level on startup, but as soon as the system was moved it all, the attitude estimate started moving around in huge gyrations, while the quad was still on the ground. I was able to reproduce this once inside before reflashing with the EKF filter. The attitude estimate looked good with this filter, but then it was still good when I went back to the Madgwick filter. I tried leaving the quad outside and retesting, on the hypothesis that it was temperature related, but was unable to reproduce the issue again.

Reproduced again at room temp, using the madgwick filter.
