Almost every time I fly my P4P, I end up at some point having to fly in ATTI mode due to loss of GPS signal. It goes in and out of ATTI mode.   I downloaded the flight log from my last flight and errors were:
GPS communication error. Please restart the aircraft.
Satellite Positioning Off. Fly with caution
GPS Position NoMatch
GPS disconnected.

Hi, I am sorry for the trouble that  your DJI Phantom 4 Pro has caused. Prior from this GPS issue, did the drone had any hard landing or crash?  I would recommend please try to do a Compass calibration to isolate issue and can you please try to fly the said drone to a different location to see if the will still persists. If issue still persists please try to do a firmware refresh using the DJI Assistant 2. In addition, I will be posting a link ( https://www.dji.com/downloads/so ... t-dji-2-for-phantom ) for the DJI Assistant 2 for the DJI Phantom 4 Pro and an official DJI Tutorial Video. Please keep us posted for further assistance. Thank you.

I have done all that you mentioned and still goes into ATTI mode within a minute or so of flight.  I recalibrated the compass, reinstalled the last update

It does this every time i fly now.  I dont remember any hard landings and no crashes.  I always fly in a different location.  

Please advise.

I am terribly sorry for the late reply, in this case, I may suggest that you send in the drone for diagnosis. Please fill out the online repair request on our official web and then send it back. Here is the link: https://repair.dji.com/repair/index?site=brandsite&from=nav. Thank you.
