The answer is simple: there is no GPS flyaway. I have seen no credible theory or evidence to support its existence. Someone prove me wrong.
I have no proof, just a speculation of how erroneous GPS data could cause a flyaway.ianwood said:The answer is simple: there is no GPS flyaway. I have seen no credible theory or evidence to support its existence. Someone prove me wrong.

I believe that taking off in GPS mode without acquiring enough satellites there can be a fly-away. I have witnessed it. Here is the the account of what happened and when.

0:00 Power up the Phantom 2. Controller in GPS mode. Version 1.08.
0:27 CSC invoked before satellite acquisition has completed.
0:36 Full power and take off
0:37 With only an up Throttle Up stick used, the Phantom 2 flies away heading East
0:48 Controller's Mode is switched from GPS mode to ATTI mode to begin recovery of fly-a-way Phantom 2.
1:15 Phantom is returned and landed in ATTI mode.
A few minutes later the Phantom 2 is flown successfully in GPS mode after the appropriate start-up sequence is followed and CSC is performed after enough satellites are acquired.
How would you describe the cause of this fly-a-way?
SteveMann said:I wish that DJI provided some kind of data logging that could be analyzed. Some flyaways are relocated later and the data could be quite revealing.

A theory has been extensively tested and is generally accepted, while a hypothesis is a speculative guess that has yet to be tested.ianwood said:Everything is a theory until it is proven otherwise.
ianwood said:Possibly but my goal is really to flag false conclusions. When it comes to flyaways, there are way more conclusions than there is evidence to support them.

Based on what? There is zero evidence to support this possibility.
