Compass not aligned and communication towers

Hi i just get this message which refuse to Arm the quadcopter “compass not aligned” but it looks like it came in particular location. Is there any real relation between existance of telecommunications towers “photo Attached” like the one the picture and this kind of errors “distance is around 1.2km”

Normally “Compass not aligned” means that your internal compass and external compass is not pointing in the same direction. Maybe redo the compass calibration or disable the internal compass. Looking at the photo it, could it be that the earth contains a lot of iron? In the past I have also seen compass issues on the ground when operating in very stony (containing iron) areas.

Thanks for the reply, actually it’s only external compass some time we receive the alarm some time no alarms and flying normally…!
