The A3 series flight controller is ideal for in industrial and commercial fields looking to increase their drone's accuracy and reliability. 

The A3 system can use D-RTK GNSS for increased, centimeter-level positioning accuracy compared to other GPS solutions. 

The A3 with D-RTK GNSS gives users extremely accurate flight control and precision, for any industrial endeavor. 

D-RTK GNSS allows for precise positioning that is within a few centimeters horizontally and vertically. 

With dual antennas, the system is able to withstand any magnetic interference from surrounding metal structures and with the D-RTK system, the A3 does not rely on the Compass or the Barometer for heading and altitude readings thus making it extremely accurate.
