This bundle from DJI features the A3 plus two upgrade kits that, combined, yield a complete A3 Pro Flight Control System. With three IMU/GNSS systems, the A3 Pro provides triple redundancy, ideal for mission critical applications where failure is not an option.

The A3 Pro system is optimized for professional and cinematography applications, providing navigation and stabilization to quad-, hexa-, and octo-rotor aircraft. The system features GNSS, which means it can use satellite systems, such as GPS or GLONASS, in combination with a compass to provide precise positional data. The A3 Pro can be used in combination with DJI’s Lightbridge 2 system to provide a high quality video downlink from a gimbal-mounted camera. Ground station software enables features, such as telemetry monitoring and route planning, and provides a flight simulator (additional ground station hardware required). It features support for DJI gimbals, including the Zenmuse Z15 line and the Ronin-MX. Mobile and Onboard SDKs allows developers to program custom solutions tailored to industry-specific use cases.

A3 Pro Features

Note: To complete the A3 Pro system one standard A3 is required

Triple Modular Redundancy

The A3 Pro gives the system 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


Fault-Tolerant Control

The new attitude determination and multi-sensor fusion algorithms improve the A3 Pro’s control accuracy. The robust control algorithm enables the 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

Optional D-RTK GNSS

The A3 Pro supports separately available D-RTK GNSS for centimeter-level positioning accuracy compared to a normal GPS and barometer solution. Using dual antennas, its heading reference is more accurate than a compass sensor, and it is able to withstand magnetic interference from metal structures

Ground Station

Ground Station Software

Supporting both touchscreen and mouse and keyboard, the redesigned Ground Station can support mission design, for use in a range of industry applications. Users can simultaneously manage and monitor the mission implementation of multiple aircraft and plan formation flights. Ground Station is compatible with the Matrice 100 and Matrice 600, Phantom 4, and DATALINK hardware (all available separately)


The separately available DATALINK PRO operates at a frequency below 1 GHz, and works over a range of up to 1.2 miles. It integrates seamlessly with the A3 Pro and D-RTK as well as the Ground Station, which allows up to five aircraft to be controlled from one base station. A broadcast mode lets the base station broadcast data to 32 mobile devices and a duplex mode keeps data locked to one device

Assistant Software

DJI Assistant 2 allows you 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

SDK Support

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
