INTEL® FALCON™ 8+ UAS

EVENT
In GPS-Mode:
Position accuracy of the UAV
is low, and it starts drifting
from its current position.
In GPS-Mode:
The UAV does not seem to
react to the control inputs of
the pilot while the data link is
not disturbed.
In GPS-Mode:
The UAV is swiftly flying away
from its current position
during vertical take-off.
In GPS- or Height-Mode:
The UAV performs strong
changes in altitude, which
have not been commanded
on the CTR.

POSSIBLE ACTION
Switch to Height-Mode and control the UAV in
Height-Mode.
With low GPS reception quality, the UAV might not
have automatically switched to Height-Mode yet,
and therefore drift from the current position prior to
being detected by the sensors is possible.
Switch to Height-Mode and control the UAV in
Height-Mode.
In GPS-Mode, the right control stick on the CTR com-
mands a specific speed. If the speed accuracy is low
because of low GPS reception quality (but not yet
automatically activated Height-Mode), the reactions
to control commands might be slow.
Switch to Height-Mode and continue the vertical
take-off to get to a safe distance from the ground
and other obstacles quickly. Control the UAV in
Height-Mode.
The compass sensors might have been disturbed on
the ground and the compass error estimation algo-
rithms do not yet have enough information from
other sensors to work with sufficient accuracy. After
receiving enough input from the IMU sensors, the
compass error estimation algorithms are usually
able to stabilize the position control even in GPS-
Mode.
"FLIGHT MODES" on page 120 for further informa-
tion.
Switch to Manual-Mode and perform a controlled
landing. Get help from support to analyze the cause.
Throughout the duration of a mission, there can be a
drift of +/- 5 m in altitude due to all cumulative
errors: temperature, drift, weather changes, etc. If
stronger changes occur, there might be a malfunc-
tion of the barometric sensors, which needs to be
analyzed.
Because of the triple redundant flight control of the
Intel® Falcon™ 8+ UAV there is a very low probability
for this malfunction to occur.
