Figure 3.14: GPS accuracy (continued)
Figure 3.15: Shadowing
The position accuracy can be impaired when obstacles block the direct line-of-sight
from many satellites. The obstacle virtually casts a GNSS-shadow over the concerned
area. This results in fewer received satellite signals and a changed geometry of the
signals themselves. This effect is very common in urban areas, where satellites can be
blocked by tall buildings. You may experience one side of the street has good position
accuracy, while on the other side position accuracy is extremely poor. If the UAV moves
out of the shadow and more satellite signals can be used to calculate the position, the
UAV can suddenly change its position due to the new calculation. Therefore, the pilot
needs to pay special attention in such situations. Whenever there are potential
shadings of the GPS signal, it is recommended to not use GPS-Mode but to activate
Height-Mode on the CTR.

IMPORTANT:
The GPS receiver module of the Intel®
Falcon™ 8+ UAV is placed directly
underneath the canopy of the central
unit and is surrounded by an antenna.
The canopy of the Intel® Falcon™ 8+
UAV is made from a material which
does not influence the satellite signals,
but anything on the top of the Intel®
Falcon™ 8+ UAV can potentially disturb
the signal. Never cover the GPS receiver
module nor the antenna area to ensure
best possible GPS reception.
