I have error 27 (GPS not calibrated, or magnetic field interference. Please calibrate GPS again in good condition) when I plug my phantom to assistant software. I try the advance calibration and went out and do the calibration dance but when I plug in to my pc, it still shows error 27 Is this error a big issue? how can I fix it?
To do advanced calibration, you need to make sure there is no electronic intereferance around, it is very important, or you will not success.
check the compass value by turning the Phantom 360 degree, if, you see the value go beyond the limit as stated when you move the cursor to the question mark, I remember something like 5500?
How I did is, In the middle of a room where there is no electronic device near by, find a table and put the Phantom on It, in the middle of that room, wooden table, not metal one. Then I use a long usb to micro USB cable, to connect the Phantom to PC, try to be as far as possible from both.
Then I do the advance calibration.
Hope this trick help. It is important that to keep metal away fro Phantom when doing the calibration.
If at theend still get the error, then suggest to do this outside, in an open area.
If still no help, check with your dealer for repairI guess.
