Global Time Echoes: Raw RINEX Consistency Test — Multi-GNSS raw-RINEX Single Point Positioning across 539 stations (1.17B pair-samples): pure annual harmonic dominance (A_1/A_2 ≈ 3.98) phase-locked to perihelion, >5.5× equinoctial artifact suppression, and dual-frequency ionospheric persistence (r = −0.416, 2.5σ).

Global Time Echoes: Distance-Structured Correlations in GNSS Clocks — Multi-center analysis of 62.7M station-pair measurements across CODE, IGS, and ESA (364 stations, 2023–2025) revealing distance-structured clock correlations (λ_T = 3,330–4,549 km) and autocorrelation-corrected orbital velocity coupling (r = −0.763, ~3.0σ).

Global Time Echoes: 25-Year Analysis of CODE Precise Clock Products — 25.3-year longitudinal analysis of 165.2M station-pair observations (2000–2025) documenting persistent velocity-dependent clock correlations, spherical-horizon EW/NS anisotropy (R=2.13), 18.6-year lunar nutation, and CMB frame alignment.

Temporal Topology Saturation Scale: Cross-Scale Consistency of ρ_T — GNSS-anchored saturation density ρ_T≈20 g/cm³ and zero-parameter two-branch SPARC radial-acceleration fit across 175 galaxies / 3,389 radii (0.2004 dex RMS action-derived additive at Υ_d=0.35, matching MOND 0.1989 dex; 0.1974 dex quadrature; null structural correlations).

Global Time Echoes: Empirical Synthesis — Cross-scale synthesis of 25.3 years of GNSS clock covariance (165.2M pairs, λ = 3,210 ± 389 km), SLR optical bounds, two-branch SPARC rotation-curve dynamics (0.2004 dex RMS), wide-binary screening, and unstretched-space ADM gravitational lensing.

🕰️ Analyze 25 years of GNSS clock data to uncover correlations, ensuring reliable timekeeping across global networks.
