I'm told you guys may be the one that might be able to help. Took my drone up to take some pics of fireworks a few nights ago. GPS signal dropped out and whenever it came back, it appears there are multiple error messages in the log of, "GPS Position NoMatch". I tried to get it back to me via attitude mode but the wind was picking up and I quickly lost visual sight of it. Tried to find my way back using the video feed but it was dark and couldn't orient myself. I'm hoping it is possible to recreate the flight path without the GPS by using the vertical, horizontal and other information. At the very least, I'm hoping to get an idea of what direction it was headed when the signal with the remote was lost. You can reach me on the forum but more quickly at [email protected].
