DJI A3 Upgrade Kit

The A3 can be upgraded to A3 Pro by using two A3 Upgrade Kits. 
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.
