Managing drone traffic in shared airspace presents unique technical challenges as UAV numbers grow exponentially. Current systems must process real-time data from thousands of drones, each transmitting position, trajectory, and status information at 1-10 Hz. When scaled to urban environments, this creates data streams exceeding 100,000 state updates per second that must be analyzed for conflict detection and resolution.

The fundamental challenge lies in building scalable systems that can ensure safe separation between aircraft while managing the computational complexity of processing high-frequency state data from numerous heterogeneous platforms.

This page brings together solutions from recent research—including cellular network-based traffic management architectures, secure geo-fencing systems, distributed collision avoidance networks, and anomaly detection frameworks for beyond-line-of-sight operations. These and other approaches focus on practical implementation of safety-critical traffic management capabilities that can scale to support growing drone operations.
