Autel Alpha - 2.6.3 Visual Positioning Function

Chapter 2 Flight Safety 15
in good lighting conditions. Additionally, it uses the bottom millimeter-wave radar only for
assisted landing.
Visual Positioning Function
The aircraft supports the visual positioning function even without GNSS signals. It means that
the aircraft can provide flight positioning capability in case of poor or no GNSS signal to ensure
flight safety.
When there is GNSS positioning information, the visual positioning function supplements the
aircraft's position information, enhancing positioning accuracy.
When there is no GNSS signal and the environment and height cannot meet the visual sensing
system, that is, when there is no GNSS signal and visual positioning failure at the same time, the
ATTI mode will be activated.
Warning

If you do not have extensive flight experience, do not fly the aircraft beyond your visual line
of sight.
 When the aircraft relies on visual positioning to fly, please do not approach mirror reflection
areas such as water or snow. When the GNSS signal is poor, please make sure that the
aircraft flies in a well-lit environment and over object surfaces with clear texture.
Tip
In the event of GNSS signal loss or weakening during flight, the remote controller will display
the following warning prompts:
 If the takeoff point is inaccurate: The Autel Enterprise App will display a warning saying
"GNSS signal is weak, home point may have deviation." with a corresponding verbal
warning.
 If GNSS signal is weak: The Autel Enterprise App will show a warning saying "GNSS signal is
weak, please fly away from buildings." with a corresponding verbal warning.
 If GNSS is being spoofed: The Autel Enterprise App will display a warning saying "Aircraft is
being subjected to GNSS spoofing." with a corresponding verbal warning.
 If the aircraft is in ATTI mode, the Autel Enterprise App will show a warning saying "No GNSS
and visual positioning, please be cautious." with a corresponding verbal warning.
 If GNSS is manually turned off and aircraft positioning is available, the Autel Enterprise App
will show a warning saying "GNSS is turned off, visual positioning signal is normal/weak,
please fly with caution." with a corresponding verbal warning.
 If GNSS is manually turned off and aircraft positioning is lost, the Autel Enterprise App will
display a warning saying "No GNSS and visual positioning, please be cautious." with a
corresponding verbal warning.
