Re: [Paparazzi-devel] Your experience with GPS failings in flight?

[Prof. Dr.-Ing. Heinrich Warmers]

Hi,
we had problems by the use of  different video camera systems  that prevent a GPS fix.
After  coating  the camera with a aluminium foil we got a fix  but poor   accuracy.
As we made flight  experiments with large roll angel (>70°)  we lost  accuracy for altitude  (about 30-60m error).

I have never experienced an in flight failure of the gps mainly because i work the system on the ground experimenting with many things for a long time before i install it in the aircraft.
Until now only one gps unit has failed and that was on the bench after ~1 hour of operation (setup etc).
Also never lost gps lock in air except from one time a long time ago due to an airborne pentax camera
that produced enough interference in order to make the gps loose the 3d lock.
I wasn't expecting this but fortunately the plane was in standby mode overhead.

Hi all,

I'm curious to learn a bit about how often and in what ways GPS can go wrong while flying at the altitudes that scale aircraft typically fly.  I'd love to hear about the experiences you've had with GPS inaccuracies and/or failings, and how often you've had these troubles

Thanks a lot!
