GPS Mode Issue, Phantom Flying in Circles

[KJMetcalfe]

I went flying yesterday and had the Phantom in GPS Mode. It acquired all satellites but it did not maintain position, it kept flying in a 20 foot radius around me which seemed to progressively get worse. I switched to Atti mode and it stopped at least flying in circles.

I upgraded to the new 3.16 Naza software which requires you to also update the controller as well before I took it out. I don't know if that is related or not.

Did do something like this??

I am trying to find out why this happened as well.

Did you calibrate your compass right before the flight?

I did not, before flight I had a good compass reading. But I did afterwards and still had some trouble flying straight lines.

I think what's you're describing is called TBE, isn't it?
