The precision of the visual and acoustic system can be affected by the illumination intensity
and the surface texture of articles. And the ultrasonic will not measure the distance in certain
damping materials. If both vision and ultrasonic do not work, the flight mode will be turned into
the Attitude mode automatically. Therefore, please notice the following conditions during flight:
y The normal flight height of this system ranges from 0.2m to 6m. Please stay in this range when
the aircraft is used indoor;
y The illumination condition is 10 lux–100000 lux;
y Within the required range of the illumination conditions, all textures could be used to position
the flight except pure colors (such as pure black, pure red, pure white and pure green);
y Be cautious on the surface where there is intensive reflected light or inverted images;
y The flight speed should not be too fast and the highest speed should not exceed 8m/s(17mph).
y The maximum flight inclination should not be more than 30°.
y The range of flight temperature is -10ć-55ć(14 F to 131 F).
y The flight altitude should not be more than 4000 meters (13,000 feet).
Ȥ In Mode P and when the GPS signal is lost or not good enough, the system will turn to the visual and
acoustic positioning mode and no manual operation is needed.
Ȥ This system is only open to GDU Byrd Advanced/Premium version.
Stowage Dropping
GDU Byrd could load with less than 500g loads (not including the gimbal and the camera) to
deliver objects from a long distance.
Before the ejection, the buttons C1 and C2 should be customized to choose the ‘steering gear
control’ in the APP setting interface. The objects to be ejected are to be put into the container
