How do drones in drone shows manage to calibrate their positions so precisely?

Question

Surely they can’t be using GPS for positions just a few feet apart.

Also, how quickly can they respond to wind and such?

Answer 1

Each drone monitors the relative positions of the drones around it using infrared and wide band radio.

This data is all transmitted back to a central computer which can use these relative positions to calculate the absolute positions of each drone, and transit course corrections in real time.
