Hi all, I have seen this question come up on other forums for phantoms etc but with no real answer, however not found anything on here. I have a conundrum, in that I have a potential job flying from a huge steel ship to survey stuff, but I need to be able to calibrate the compass. I will be hundreds of miles offshore, without the ability to hop on a small dinghy or land to do a calibration. Is there a way to do it? I have thought about large poles to hold the inspire a long way up in the air, but this seems logistically tricky. The alternative is to insulate the inspire from the steel surrounding it somehow during the calibration. Alternatively is there another quad or flight controller out there that is capable of some sort of manual calibration? If anyone has any experience, or knows THE way of doing this sort of thing (if at all...) I'd be really grateful.
