Phantom 4 RTK User Manual
In Absolute Height mode, make sure to use RTK positioning. In Relative Height mode, the takeo
points for planning tasks and for executing tasks must be at the same height.
When importing KML/KMZ les, make sure that the type of coordinates in the le is “LineString”
and that the altitude mode is “absolute”. If the altitude mode is not “absolute” or there is no
information for altitude mode, only latitude and longitude data will be imported. Users can set
height for each point according to the height mode preset in the DJI GS RTK app.
In Absolute Height mode, follow the instructions below to obtain a more precise absolute height
for the point in the flight area. Firstly, fly the aircraft to the point and add the point using the
latitude and longitude of the aircraft. Then y to one side of the target object, set the gimbal
angle to 0, which means that the gimbal is facing the front of the aircraft, and move the aircraft to
align the center of the Camera View to the top of the object. Mark down the rtkH value on the left
lower corner of the screen and set the height of the corresponding point to this rtkH value.
4. Set the extension length: Tap Extension and set the extension length to the left and right when generating
the linear ight area. Left or right refers to either side of the line connecting recorded points. The dotted
box displayed on the screen after conguration is a preview of the width of the linear ight area.
5. Tap Next, and the app will automatically generate a corresponding ight route, which is a single route
covering the whole linear ight area.
6. After the ight route is generated, there will be a settings list on the right side of the screen. Congure the
settings accordingly.
The height in the settings list refers to the aircraft’s vertical height relative to the plane where the added
point in the linear ight area is when performing the operation. Other settings are similar to the ones for
other operation types.
7. Tap Save, name the operation, and then tap OK.
Angled Flight Route
In Angled Flight Route operations, points A, B, and C can dene the inclined or vertical target plane so
that users can plan and execute missions. Fly the aircraft to the desired positions and set the position
and altitude of the aircraft as points A, B and C to dene the angled plane, or import a KML le to add
points, and then configure the extension length and other settings. The app will automatically generate
the corresponding ight area and ight routes. Once chosen and congured, mission will be carried out
automatically, following the ight route in the ight area. This is suitable for photogrammetry data acquisition
for reconstructions of slopes and buildings.
