I was wondering if I could just wire the UBLOX ( https://www.u-blox.com/en/product/c94-m8p ) to the input of the 3DR brain to get a centimetre accuracy and create a mission with way points to create a light patter with my custom drone.
It sounds a bit overkilled but which this chip I should be able to get my drone to move almost to the correct point rather than getting a ~1 meter of shift.
