gps errors

Does anyone know why my phantom 3 pro is going in and out of GPS mode when i'm video taping? I am not sure how to correct this issue.

Hello, I have a lightly flown (probably 3+hrs total) P2V+. When I connect it to the PH2 software, I receive a "Calibration Error" with no number associated. I have tried to recalibrate the compass, no joy. If I turn the bird on and it's sitting on a level surface I receive the steady red...

Ok so I've watched countless videos and read the instructions as well as forums and yet everytime I calibrate the gps it never does what the video shows. What am I doing wrong...besides not breathing, standing on one foot, elbows at 42.5 degrees and with only one eye open?
