Introduction
The DJI A3 series is a reliable and robust flight control system that is ideal for a wide range of
multirotor aerial platforms. It uses advanced sensor fusion algorithms and redundancy design to
maintain complete stability and integrity of the aerial system.
The A3 series is fully compatible with the DJI Onboard and Mobile SDKs, allowing developers to
optimize the system for specic applications. When used with the DJI Lightbridge 2, it has direct
access to features in the DJI GO app such as Intelligent Flight Modes. With DJI Guidance, the
aircraft can maintain hovering accuracy and obtain obstacle sensing information for safety. The A3
series is compatible with the DJI Intelligent Landing Gear, Zenmuse Z15 gimbal, Parachute and
higher accuracy RTK GPS.
With all essential components integrated into the A3 ight controller (including the IMU, barometer
and data recorder), the device is powerful and highly compact. The A3 can be upgraded to the
A3 Pro by installing two upgrade kits. The A3 Pro’s three GPS units and IMUs add triple modular
redundancy to greatly reduce the risk of system failure.
*The GPS-Compass Pro modules in the A3 Pro upgrade kit are the same as the A3’s. The IMU PRO module
includes an IMU with a built-in Barometer.
System Components
How the System Works
The flight controller is the core module of the A3 fight control system, which utilizes the IMU,
barometer, GPS and compass to realize accurate attitude control and high-precision positioning
for the aircraft. Multiple interfaces for SDK development and DJI devices, such as the RTK
GPS and Zenmuse Z15 gimbals, are also provided. The DJI Assistant 2 software allows you to
congure parameters for installation, ight control, and other accessed devices. A simulator is
also available for simulated flight practice. When used with the DJI Lightbridge 2, the A3 has
direct access to features in the DJI GO app such as Intelligent Flight Modes.
