Usually disturbances on the ground come from underground lines and can quickly be
resolved by switching off the Intel® Falcon™ 8+ UAS. Chose a different starting position,
switch the UAS on again and check if the magnetic field warning is not shown again. In
many situations, the disturbances are limited to small areas. If this is not possible, you
can:
1. Switch to Height-Mode and take off in Height-Mode to avoid any position
corrections by the system, which might occur unexpectedly in GPS-Mode.
2. Fly to open space and keep Height-Mode activated for at least 20 seconds (it will
help the estimation algorithms to do some movements forward, backward, left and
right).
3. Switch to GPS-Mode in open space. The magnetic disturbance will then be at a safe
distance and the estimation algorithms will be active.
4. Always be prepared to switch back to Height-Mode anytime.

Figure 3.8: Magnetic Field Warning
Since the IMU sensors (like accelerometers) are
needed to estimate the heading, the compass esti-
mation does not work if the UAV is standing still
on the ground. During start-up, the current mag-
netic field is com-pared to the expected magnetic
field. If there is a discrepancy, there will be an unin-
terrupted acoustic signal. The Status Display will
display the shown warning.
If this warning occurs, never take off from that
spot in GPS-Mode! It might lead to unexpected
positional changes of the UAV.
The warning can be canceled by pushing the ENT
button of the Status Display on the Intel® Cockpit
Controller (CTR).
IMPORTANT:
As long as the Intel® Falcon™ 8+ UAV remains
switched on, the canceled magnetic field warning
will not be presented again. So, if the Intel® Fal-
con™ 8+ UAV is moved to a different location
while switched on, there will be no warning, even
if there is a magnetic disturbance present.
