DJI A3 flight controller series.

The all-new DJI A3 series of flight controllers is ideal for demanding industrial and cinematic applications where reliability and customization is essential. With D-RTK GNSS, the controller boasts centimeter-level accurate positioning and triple modular redundancy when upgraded to the A3 Pro, giving the system unprecedented reliability. Using the all-new Ground Station, up to 5 aircraft can be controlled simultaneously and complex maneuvers planned in advance.

The A3 Pro* is equipped with three IMUs and three GNSS units, with additional analytical redundancies for a total of six redundancies. Working together with advanced diagnostic algorithms, if the A3 Pro detects GNSS or IMU unit failure during flight, it seamlessly switches to another unit to maintain reliability and precision.

*Upgrade the A3 to A3 Pro by installing 2 upgrade kits. (People are getting excited about the A3 Pro but not reading this line… ed)
