7.1.8 GNSS denied mode
GNSS failure during Mission
In case the Vector does not receive reliable GNSS position data, the Vector will enter the GNSS denied mode. QBase will
display a warning.
As no GPS positioning is available the current position is estimated indicated by the dotted circle in QBase. The radius
increases with the position uncertainty over time. In GNSS denied mode, the position in the map is not accurate.
Options during coming home
1. Continue the mission. Please be aware that the position in the map is not accurate. Continuing the mission is not
recommended and should only be considered if really necessary.
2. Select "Coming Home". The Vector will enter the descent circle and perform the retransition and landing at the estimated
location. The vehicle will not enter the hover-to-base mode (except if the vehicle is able to reestablish the GNSS signal).
3. Fly manually. This is recommended if the GNSS drift (displayed by the dotted circle) is too large and a safe landing is no
longer guaranteed. Select "land now" at the desired landing location to initiate an immediate retransition. If no manual
input is given for 5 seconds, the mission/coming home is continued.
GNSS failure during Hover Mode (take-off or landing)
The Vector will enter the GNSS denied mode and initiate an immediate landing at the current position. As no GPS
positioning is available the current position is estimated indicated by the dotted circle in QBase.
Note: The vehicle will drift due to wind inuence. Fly manually to compensate drift if necessary.
