Poor
GPS/GLONASS
coverage
∗
GPS/GLONASS signal coverage is low. This may be
due to mountains or tall buildings blocking satellite
signals. If coverage degrades any more a Critical fail-
ure will be activated and an emergency landing will
be initiated⁵⁹.
Security action (if enabled): The drone flies to-
wards the Home waypoint at an altitude defined by
the Home waypoint’s Change altitude parameter (by
default, set to ‘Highest’).
User action: If this occurs once or twice, click ‘ACK
WARNING’and continue normal flight. If this warning
appears more often, land as soon as possible and wait
for better conditions for satellite signal reception. Al-
ternatively, move away from objects that may disturb
satellite signals such as mountains or cellular anten-
nas.
