Architectural Layers & Protocol Stacks

• Physical RF Ranging & Two-Way Time-of-Flight (IEEE 802.15.4z Scrambled Timestamp Sequence / Nanosecond Time-of-Flight): Ultra-Wideband (UWB) RF pulses measuring inter-vehicle distances at 200 Hz with sub-2cm measurement accuracy.
• Distributed Clock Consensus & Drift Compensation (Precision Time Protocol (PTP) / Kalman Consensus Filter): Decentralized peer-to-peer clock synchronization locking swarm crystal oscillators within 500 nanoseconds without a master satellite.
• Dynamic Relative Spatial Positioning Filter (Distributed Extended Kalman Filter (DEKF) / Graph SLAM): Multi-dimensional state estimation fusing UWB ranging, optical flow, and inertial measurements into a unified swarm frame of reference.
• Coordinated Separation & Formation Trajectory (Distributed Model Predictive Control (DMPC) / Flocking Algorithms): Decentralized potential fields and receding horizon controllers generating collision-free swarm morphing maneuvers.
