I am preparing for a swarm flight this time.
It seems that sophisticated GPS is the most important.
I don’t have money, so I want to control 5 to 10 quadcopters
The distance between the drones is thought to be about 5m.
Which RTK do you think is the best for swarm?
Looking at all the RTK descriptions, everyone says that they are the most accurate and superior.
What should I believe?
