|
|
Aim of this project is the automatic start and landing of an UAV from a moving ground vehicle. To manage this aim the task will be enclosed in the following section.

# Flight phases
|
|
|
For this project the landing of the UAV will be in the focus. The landing procedure can be split into two parts or flight phases, as seen in the picture below.

The first flight phase is the non precision approach(NPA) in which the UAV navigates to a waypoint which is set to the position of the ground vehicle. The position data of the GV is provided via a datalink between the UAV and GV. This approach is dependend on the accuracy of the the UAV and GV using GPS, which is to uncertain for an landing. Thtas why this approach is there to establish the second flightphase the
