2.1.5 Flight Control System
EVO II Pro V3 aircraft provides stable and convenient flight control through its
built-in intelligent flight control system. The system supports multiple advanced
functions, such as return to home, failsafe, and Starpoint positioning. Each module
is described in the following table.
Intelligent Flight Control System
Module
Description
IMU
Use a 3-axis gyroscope and a 3-axis accelerometer to measure
the acceleration and angular velocity.
Compass
Measure the geomagnetic field and provides reference
information on the aircraft heading.
GNSS receiver
Receive signals from global navigation satellite systems and
determines the 3-D position (latitude, longitude, and altitude)
of the aircraft.
Barometer
Measure the atmospheric pressure and determines the
altitude of the aircraft.
Ultrasonic sensor
Measure the distance between the aircraft and the ground.
Binocular vision
sensing system
Support omnidirectional binocular vision (front, rear, left,
right, up, and down).
1. Flight Mode
The aircraft can automatically switch between three flight modes based on the
availability of GPS signals and flight conditions.

Flight Mode
Description
GPS mode
The aircraft will activate the GPS mode once it detects a
sufficient GNSS signal. In GPS mode, with the assistance of the
front and rear vision systems, the aircraft can locate and avoid
obstacles. GPS provides stable and smooth flight control and
supports features such as return to home and failsafe.
ATTI mode
The aircraft automatically changes to ATTI mode when the
GPS signal is weak, and the vision systems are unavailable due
to the poor light conditions. The obstacle avoidance feature is
disabled, and the aircraft controls the altitude through a
barometer.
