The A3 Pro upgrade adds 2 extra IMU and GPS units for complete redundancy in your flight controller system. All of the parts work in unison to deliver precision accuracy and extremely stable flight.
Two upgrade kits must be bought to make the system an A3 PRO.
Very easy to install and set up. We have used many of these on custom builds for use all across Canada and the USA. Adding redundancy does not add accuracy but it does give regulators and you better peace of mind about the dependability of your UAV.
DJI sends these units out with fixed masts. We are now stocking foldable GPS masts that are a must when adding the A3 PRO Upgrade to the Matrice M 600 or any other UAV for that matter.
