land. Check that the flight area has no obstacle that
might interfere with flight phases or prevent visual
contact.
• Make sure the flight altitude programmed in
Pix4Dcapture (entered in relation to take off point)
is sufficient to avoid obstacles in the surrounding
area.
PARROT BLUEGRASS
• Make sure that Parrot Bluegrass has detected the
GPS signal in FreeFlight Pro or Pix4Dcapture.
• Make sure the Parrot Bluegrass propellers are
properly mounted and secured.
• Make sure the Parrot Bluegrass battery is charged.
• Make sure you are in a wide, open space.
• Make sure that the selected geobarrier distance
is sufficient for the execution of the flight plan on
Pix4Dcapture.
SEQUOIA
• Make sure that the lenses are clean. Use the
microfibre cloth (supplied) to clean them.
• Free up enough memory (on the SD card or in the
multispectral sensor internal memory) so you can
save all the photos taken during the flight.
• Make sure that the two sensors are calibrated. For
more information, see the Calibrating Sequoia
section.
