How It Works

Chronometric interferometry + adaptive consensus → fiber‑class wireless time

Estimator Pipeline

  • Probe: multi‑tone + chirp waveforms
  • Detect: matched filter + CLEAN for LoS
  • Estimate: phase‑slope τ̂, group‑delay Δf̂
  • Fuse: Kalman filter + quality metrics

Adaptive Consensus

  • Topology‑aware, robust aggregation
  • Byzantine tolerance target ≈ 33%
  • Convergence speedups via hierarchy
  • Scales linearly to 500+ nodes

System Integration

  • Exports to PTP/gPTP/TSN clocks
  • Open RAN timing hooks
  • Fleet QoS, auto‑calibration, alerts
  • SDK: τ/Δf + quality as API

Plainly: we measure path delay and frequency offset with high SNR using engineered waveforms and interference‑aware estimation, then reach network consensus on time while rejecting bad actors and multipath outliers. The export surface is standards‑friendly so existing systems can adopt it without rewrites.

See analytics/E1_E13_comprehensive_results.md for validation details and docs/PTP_BRIDGE_INTERFACE.md for PTP/gPTP integration.

Interactive Consensus (Concept)

Nodes (spheres) converge in phase; color ≈ phase error (ps). Edges depict communication links.

LoS Extraction (CLEAN‑like)

Matched‑filter magnitude with iterative peak subtraction; isolates the direct path under multipath.

Chronometric Interferometer

Multi‑tone superposition; phase‑slope across tones visualizes τ̂ sensitivity. Adjust SNR to see CRLB effects.

Hierarchical Consensus

Cluster aggregation visualizes scalable convergence. Links depict cluster → root communication.
