[QUOTE="Rick Morton, post: 17111, member: 2166"] Yes. I have the Refresh care thing so it was only $49. They'll do that twice. From what I understand, it's not so much that you're losing GPS as it is that the GPS system needs a good compass to work. The GPS only registers a POINT on the map. The compass is what the Spark uses to update it's location by knowing what direction it's moving. So, apparently, if the GPS system thinks it's going north, but the bad compass is heading west, all hell breaks loose. The message we get is Lost GPS and it goes into ATTI mode. This, actually, is a safety feature saying, in essence "I can't talk to your compass so you take over". Compass calibration is really important and perhaps more important than DJI makes it out to be. I'm not an expert. Just relaying what I've learned in my searching for an answer. [/QUOTE]
