height of the relevant obstacles within or close by your mission area before programming the
mission.
11. Verify that the GNSS LED module is solid green. If not, please fly a varying trajectory until it is.
NOTE STORMBEE S20 is equipped with the Applanix APX-20 GNSS-inertial module and a
single GNSS receiver. Compared to systems that have two GNSS receivers (mounted
on long arms), the heading of STORMBEE cannot be directly measured by comparing
the positions of the GNSS receiver. Therefore, it requires STORMBEE to first fly a little
(10 seconds or so) to be able to determine the initial heading from the flight's
trajectory. Ideally, this required time window will be at the same moment when you
verify the response of STORMBEE immediately after take-off before you start the
(automated) mission.
NOTE It is possible that the GNSS LED module during flight starts blinking green again after it
was continuously green. This indicates that the GNSS GPS signal acquisition is
(temporarily) of lower quality. As long as this only occurs for a few seconds at a time,
the final point cloud data should still be of sufficient quality.
12. If all take-off checks are fine, you can start flying your scanning mission, either manually or
automatically. In the latter case, you may now press the plane icon in the top-right corner of
the GS Pro app. Verify that all mission elements are green and OK and press the
“Start to fly”
button in the DJI GS Pro app to let STORMBEE perform its automated mission.
NOTE When the automated mission is started, STORMBEE will first climb straight up to the
altitude of its first waypoint. Then it will turn towards the first waypoint after which it
will fly towards it. After reaching the first waypoint, it will hover, turn towards the
second waypoint and follow the consecutive waypoints with the velocities, altitudes
and headings according to the programmed flight path. The DJI A3 flight controller is
quite aggressive when flying towards the first mission waypoints as the velocity
restrictions only apply from the first waypoint onwards. This behaviour is normal.
NOTE It is best to program the STORMBEE to hover when reaching the last waypoint after
which the pilot should then manually (in P-GPS mode) fly STORMBEE back to its landing
area and land.

WARNING!! Regularly (every minute) check the mission health status and the FPV camera view on
the DJI GS Pro app regardless of what flight mode the STORMBEE is in. Check the voltage level of the
STORMBEE flight batteries every 30 seconds! Abort the mission and return to landing site to land
when the voltage level drops below 21.6V. Land ASAP at current location if voltage drops below
21.4V.
Continuously switch your attention between STORMBEE, battery level, FPV camera view and
small mission window.
