Sorry?You miss my point, I was simply trying to show LED’s on drone.
If there is any interference with the compass I will know by analyzing the flight data in Ar Data ... correct?There should be no ref interference. They appear to be battery powered. There is some possibility of compass interference when the lights are on. The power leads will have current flowing in them creating a magnetic field When they are on.
So a calibration of the compass with the lights on before flights would be enough ?
ok thanks a lot for the explanation. I have already cleared up the doubt.
