Thank you for the information, fascinating. I've been curious about this for a while, how drone swarms are coordinated by software to perform intricate shows. There must be some interesting questions to solve, like how to avoid collision, or if they need error correction in case of wind, etc.

I learned RTK means "Real-time kinematic positioning". https://en.wikipedia.org/wiki/Real-time_kinematic_positionin...

Apparently it's possible to set up one's own RTK station. https://github.com/Stefal/rtkbase https://learn.sparkfun.com/tutorials/setting-up-a-rover-base...
