E384 – Planning a Mapping Mission

On this page we are going to see how a mission can be easily designed. In this scenario we will be using the “Survey (Grid)” method. We will outline the area we intend to survey. We will tell Mission Planner what type of camera we are using and the overlap that we desire. We will also specify flight direction, keeping the wind in mind. Let’s get started.

Firstly Select E384 from the UAV Model Dropdown box.

Now go to the Flight Plan tab and find the area you intend to survey.
Next we are going to “Add Polygon”. This polygon that you create will be the outline for the way points we will be generating. When in “Add Polygon” mode simply left click to add as many points as you desire. If you left click and hold a polygon point you can drag it (likewise with way points). If you need to delete a polygon point you can simply right click on the point and click on “Delete WP” (likewise with way points). Click Add Polygon on the right and enclose your area of interest.

Now press the Survey (Grid) button.

Select the camera that will be used.  Set the altitude to that of the desired ground resolution.  Verify that the Grid Flight Time is low enough to complete.

Now we will take care to deal with the wind properly.  We want the flight lines to be planned with a crosswind.  We also want to make all our turns into the wind, which will slow the drone down and maintain a tighter turn radius.  For this example we will consider a wind coming from West to East.  In order to fly crosswinds, we change the Angle to 180.

Now we need to make sure we are turning into the wind.  So this mission should begin in the East and make its way West.  Move to the Grid Options tab and choose to start from either the top right or bottom right.  In this case, the top right is closer to our home point, so we choose that.  In that way there is less flight to the first grid way point.

MM5

Now, move back to the Simple tab and press Accept to import the mission onto the Flight Plan screen.

MM6

Now Press Accept. An Automatic Takeoff Waypoint will automatically be added to the mission.

If you pull the Waypoint bar up, you will see the Takeoff WP has been added.

MM10

If you are performing an Auto Landing, zoom to the are you wish to land.

MM11

Press the Setup Landing button.  Left click the spot on the map that will be the start of the runway.  Left click again for the ending point.  In this scenario the wind is coming from West to East.  So the starting point will be in the East, and ending point in the West.  After clicking the map, WPs will be automatically generated.  You may drag the LZ WP to move all landing sequence WP.

MM12

Now that the mission is set, press the Write WPs button to write them to the drone.  The drone must be connected to E38 Mission Planner in order to Write WPs.

MM13

Additionally, you can use the Read WPs button to read the WP that are stored on your drone.

The mission planning, and waypoint upload is now complete. Proceed with the Preflight Checklist.
