Description
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 customisation are essential. 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.
Triple Modular Redundancy
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.
Precision Fault-Tolerant Control
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.
Industry Solutions and SDK Compatibility
The A3 series provides industry solutions with D-RTK GNSS, smart ESCs,
and Lightbridge 2. With Onboard and Mobile SDKs, custom-built applications can access flight data, and control the aircraft, gimbal, and camera. Dedicated hardware interfaces including CAN and API ports allow industry experts to craft their ideal aerial system by adding actuators and sensors.
Next-Generation DJI Assistant
The brand new DJI Assistant 2 is powerful yet simple, making it easy to set up a variety of DJI aerial systems. A new, built-in flight simulator ensures that complex moves can be practiced in advance without risking the aircraft, and a completely overhauled Ground Station supports touch screen interaction, offline mission design, route planning and even formation flight for multiple aircraft.
