The GPS Anomaly Revisited: Vacuum Impedance Explains Clock Drifts Without Relativistic Time Dilation

This paper demonstrates that the clock corrections required by the Global Positioning System (GPS)—often attributed to General and Special Relativity—are instead explained by variations in the impedance of a Structured Vacuum (V23). The gravitational offset (+45 μs/day) arises from the gradient in vacuum density n(r)=n0(1+GM/c2r)n(r)=n0(1+GM/c2r), which alters the resonant frequency of atomic clocks. The kinematic offset (-7 μs/day) results from dynamic friction as clocks move through the viscous V23 medium. The Sagnac correction, essential for GPS accuracy and incompatible with Special Relativity's invariant light speed, naturally follows from an absolute, non‑rotating vacuum frame. Thus, GPS does not validate Einstein's relativity; it validates a structured ether whose mechanical properties affect physical processes. All derivations use classical wave mechanics without curved spacetime or time dilation.
