Vision Positioning System
The Vision Positioning System helps the aircraft maintain its current position. With the help of the
Vision Positioning System, the Tello can hover in place more precisely and y indoors or outdoors in
windless conditions. The main components of the Vision Positioning System are a camera and a 3D
infrared module located on the underside of the aircraft.

Using the Vision Positioning System
The Vision Positioning System is activated automatically when the aircraft is turned on. No further
action is required. The Vision Positioning System is only effective when the aircraft is at altitudes of
1.0 to 32.8 ft (0.3 to 10 m) and works best at altitudes of 1.0 to 19.7 ft (0.3 to 6 m). If the aircraft is
beyond this range, the Vision Positioning function may be affected, so extra caution is required.
• The performance of the Vision Positioning System is affected by the surface being own
over. The aircraft automatically changes to Attitude mode when the Vision Positioning
System is unavailable. In Attitude mode the aircraft is not able to position itself. Operate
the aircraft with great caution in the following situations, which may cause the aircraft to
enter Attitude mode:
a. Flying at high speed below 2 ft (0.5 m).
b. Flying over monochrome surfaces (e.g. pure black, pure white, pure red, pure green).
c. Flying over highly reective surfaces.
d. Flying over water or transparent surfaces.
e. Flying over moving surfaces or objects.
