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

[Mark Schnittman]

Hi David (and all),

Sorry, I should have been clearer.  I am interested in what troubles people have experienced, even outside of hardware and software issues.  Your mention of solar activity is a perfect example.  I know that can be an issue, I'm wondering how often you all have seen things like that cause a GPS blackout, or very inaccurate positioning.

Thanks again!

Hi Mark,
I have not seen any GPS failure on my part while flying. I have
followed and worked with Paparazzi since 2006 and not read of
in-flight failure of GPS or even Paparazzi hardware. It probably helps
that the software inside is tested with formal methods to weed out
exceptions that could cause problems.
I noticed your question "GPS can go wrong" could be widely
interpreted. GPS itself could go wrong due to solar activity etc.
