Hi Stephen, I should have mentioned I just got this drone back from DJI would they have updated to the latest firmware? I got it back Wednesday Feb 6, my first flight was this weekend and it had this GPS issue immediately.

Stephen I tried downloading the DJI2 assistant to my iPad but nothing happened just a bunch of Binary. Is there a way to updat the firmware through DJI go 4. Or do I need. 2020 MacBook , or 2020 windows operating system. Do I connect the drone directly to my iPad or through the controller.

You should send it back and have that fixed before you lose it.  Evidently, when they fixed whatever, something else messed up.

Thank you for the information given MurrayL. Since the firmware of the drone is up to date and tried multiple troubleshooting steps the next best thing to do is contact DJI Support at https://www.dji.com/support to open a ticket for your DJI Phantom 4 Pro. Thank you.

I was waiting for somebody else to chirp in since I don't own a P4.  But it's been seven hours, so...

If it was me, I'd move to a nice wide open field away from everything and give it a low level test flight because it sounds to me like there's a real possibility that you earlier launched near some ferrous metal which influenced the compass which would create havoc with the satellite fix.

Good luck

Thanks Mark, that’s sounds like a great idea what height do you consider low flight.  Also I flew multiple flights from the location and it always gave me a strong satellite and good to launch message. I really think there is an issue with this refurbished drone they sent me.
Do you think Cold temps would throw the gps off like this? To me I don’t see why Gps wouldn’t work in sub zero temps commercial jets have been using them for years.
Thanks

Unlikely the cold temps, more than likely an issue  with the hardware or software, make sure you take off from grass, i would fly just above head height, say 10ft, i wouldnt even fly, i would just keep it in a hover and see what happens, but as Mark said, find the largest open space so you have room to rectify if it happens again

Despite what Mark says, that is a message that NEVER comes up for a compass/magnetic interference issue.
If you have a  yellow warning says GPS failure contact DJI.
You have a real problem with the GPS that needs attention.

Hello,
I just saw your subject, and I have a little bit of a problem
I turn on the drone, the remote control and the tablet, everything goes well, except that the drone finds no GPS, so the tablet tells me "take off impossible."
Just before, I made an update of the tablet and knowing that I had to change drone following a fall. I paired the drone and the remote together.
What should I do to solve this problem?

thank you for your reply

Stephen I refreshed the Firmware, flew it in a different location all together. Worked for 5 mins thought it was good. Made a second flight and it lost gps again.  Refresh downgrading and refreshing to latest version did not fix this problem.  There must be something wrong with the gps in this unit.  If you have any other suggestions for me to try I will try them.

You are wasting your time refeshing firmware or listening to people that haven't a clue.
The error message already told you what you need to do.

You should start your own thread about your problem rather than adding to someone else's.
