This is a 3D antenna tracker using a F3 FC with built-in GPS and compass. The case can be found on Thingiverse. U360gts antenna trackers have a 360 degree pan rotation and build instructions are well documented. What I didn’t get working is routing the USB-cable to the base Plattform through slip ring as it suffers from bad signals to complete signal loss. Maybe because I used a cheap slipring from Aliexpress. !
