Hello!

Today the GPS mode failed after 10 min flight. It is the first time after at least 15 flights with the new drone.
I change the battery and already after 1 min the GPS mode failed again. I flew then in Atti mode.I wonder what can be the causes of loosing the GPS signals? The weather was fine.

The flight log shows 17km that was funny.

Cant say what the reason was until we see the flight log. Go to: http://www.phantomhelp.com/LogViewer/Upload/ Follow the instructions to upload the log, copy the link to the result and come back here and post the link.

The log fot the second flight (the one with 17 km)

You have a hardware fault that is causing the GPS to drop out completely.
GPS dropped out at 0:15.6, 0:47.6, O:50, 1:43.9, 1:46.2, 2:09.5, 2:10.6, 2:11.8, 2:30.7
I'm not sure if it's a loose connection or a faulty GPS unit but it needs to be fixed.

Flew again, same results. My GPS fails after a while.
I will contact support and see what they say.

Got contact with support but they missunderstod the error and I replied again with what the real problem is.
I started my old Phantom 4 and flew 6 minutes, not a single drop in sattelites to zero. So the new Phantom 4 pro v2.0 has definitely some issue.
Todays flights

I done a short flight test so I can compare the dat file and the log file

The flight log record

And the GPS level from the dat file



The gps signal is going down from time to time according both the log and the dat file.

I got yesterday my aircraft from service. They replaced the gps module. Now it flies without any problem

Thank you for updating us all with your situation!!  Truly happy you got it all sorted out, and DJI helped you!
