I’m excited about the project. Even if the project doesn’t work out, I’ve already used this device to replace the raspberry pi + SDR that I was using for tracking aircraft with this one and it is feeding to fr24/flightaware for me with less problems than I was having with the previous hardware that I had.
Will 4Dsky become the air-traffic control layer for the entire drone industry?
Why might the world need a universal drone traffic system like 4Dsky?
If drones are going to scale into the tens or hundreds of millions globally — deliveries, inspections, security, mapping, emergency response — they need a real air-traffic system, not just GPS and hope.
4Dsky’s pitch is that this system shouldn’t be controlled by one corporation or a government silo…
but by a decentralized network of sky sensors, nodes, and data providers.
Think Helium, but for airspace:
Thousands of contributors running sky-vision nodes
Open, shared air-traffic data
Permissionless access for drone companies
Incentives for accurate data & reliable uptime
If this works, every drone would depend on the collective network, not a single centralized provider.
But can a DePIN model actually handle something as serious as air-traffic safety?




Hey all, I’ve been going back and forth on whether it makes more sense to build something from zero or just buy a small business that’s already running. It feels like there are pros and cons either way, especially when it comes to risk and time. Has anyone here actually done this, and was it worth it in the long run?
