Brushless gimbal antenna tracker

Hello there,
I project to try connecting a brushless gimbal to antenna tracker…

My need is for drone laser show, with that goal: following and pointing precisely a flying UAV with a laser mounted on a brushless gimbal. i assume the fact that the positionning would use RTK for accuracy.
I plan to do test on next month, but idea and advices would be appreciated!!
Thanks,
Julien
