OVERVIEW
Optimized for professional and cinematography applications, the A3 Flight Controller from DJI provides navigation and stabilization to quad-, hexa-, and octo-rotor aircraft. The system features GNSS, which means it can use satellites systems such as GPS or GLONASS in combination with a compass to provide precise positional data. The A3 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, as well as 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. For triple redundancy, the A3 can be updated to the A3 Pro by adding two upgrade kits.
Performance
Fault-Tolerant Control
The 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
Optional D-RTK GNSS
The A3 supports separately available D-RTK GNSS for centimeter-level positioning accuracy. Using dual antennas, its heading reference is more accurate than a compass sensor, and it is able to withstand magnetic interference from metal structures
A3 Pro Upgraded Path
You can upgrade the A3 to an A3 Pro by adding two upgrade kits (available separately)
Triple Modular Redundancy
The A3 Pro upgrade 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
Ground Station
Ground Station Software
Supporting both touch screen 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)
Optional DATALINK PRO
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 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 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
