Combining ultimate reliability with accurate flight control, the brand-new A3 series of flight controllers is ideal for demanding industrial and cinematic applications where reliability and customization are essential. 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. The new attitude determination and multi-sensor fusion algorithms improve the A3’s control accuracy. The robust control algorithm enables the A3 and A3 Pro to be adapted to a wide range of aircraft without the need for manual tuning. With a fault-tolerant control system, a hexacopter or octocopter can land safely even in the event of propulsion system failure.
