Last recorded FMS event 15m above the ground which happend just moment before the first contact with the ground, registered 13 "visible" satellites and 11 "tracked". Is it possible to receive GPS signals during barrel roll with the inverted antennas?
absolutely yes since gps does not report sattelites in a second livestream. if you have a handheld gps you can confirm this by the following : let it establish satellites fully and report a position. then invert it and look that it takes a much more time than the whole crash to report you have the satellites lost- thats all about the gps conspiraton tiger.
