There are a lot of air traffic control networking companies in the U.S., and you need to know exactly what you want to get out of it first.

I wonder what you need it for? UAVs are used in a wide variety of industries in many countries, and every year the scope of their use is only increasing.

I think it's faster to google it than to wait for an answer here. 1v1 lol

Culver Aviation has been developing and selling networked air traffic control systems in the U.S. for a long time and has a lot of experience in designing and manufacturing advanced UAVs for a long time and I am sure you can choose the drone system that is right for your needs. Their Menatir UAV control system https://menatir.com/ has been used successfully by many companies and I am sure they can help you.
