NOTE Keep at least 2 meters (6 feet) away from STORMBEE while the GNSS acquires it
current GPS position. Also keep mobile devices away that emit wireless signals such as
mobile phones or Wi-Fi routers.
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.
NOTE The GNSS avionics box has two synchronised LED modules that indicate its status. One,
small LED, is mounted on the side of the GNSS avionics box. A second, large and
powerful LED, is mounted underneath the STORMBEE to visually check its status during
flight.
15. Boot up the FARO Focus scanner. The scanner’s boot -up sequence takes several minutes. The
FARO Focus scanner will blink blue when ready.
16. Wait until the scanner and GNSS are both booted up, and the latter has acquired a good quality
GPS lock. On the FARO scanner screen, press "Start scan". The mirror will spool up and start
performing the scan. Once scanning, the scanner will start blinking red.
NOTE As the scanner is mounted upside down underneath STORMBEE, the text on the FARO
Focus scanner screen is also upside down! Be careful when pressing (virtual) buttons
on the screen of the laser scanner.
17. After the scanner has started scanning, the mirror has spooled up and the scanner has blinked
red 5 times, press the large GNSS-scanner synchronisation button (next to the GNSS power
button) to start recording the FARO Focus scanner mirror rotations and its time stamp with
respect to the GNSS position estimation. This synchronisation time stamp data is required for
post-processing the point cloud.
You are now ready for take-off!!
