I read the paper, very interesting. Did the magnetometer ever get interfered by large pieces of metal such as a steel door frame? and does the red LED turn on to signify a constant direction?
We did not have major problems with magnetometer interference. You are absolutely correct that large metal objects in buildings cause interference, and we were able to measure these (significant) effects. Two things mitigate the problem:
-We are constantly filtering to determine the low frequency "mean" of the signal. So offsets are not a problem.
-The interference tends to vary slowly in with position. So it's easy to correct for as a pilot.

Yep, the red LED is 'forward' for the pilot.
