Absolute Cosmology 07:Propagation Delay Effects in GPS Time Synchronization: Empirical Evidence from the Absolute Cosmic Transformation

The Global Positioning System (GPS) is conventionally regarded as a decisive empirical validation of Special Relativity, specifically citing a -7\ /day kinematic correction as evidence of "time dilation." This paper re-examines that ontological interpretation using the Absolute Cosmic Transformation (ACT) established in Paper IV of this series. We demonstrate that this correction is not a dilation of time, but the integrated accumulation of propagation delay incurred as electromagnetic signals traverse absolute space. Via ACT, we derive the unidirectional Sagnac delay as 66.013 ns and identify the -7\ /day figure as its arithmetic equivalent (+7.23\ /day) with an inverted sign. Crucially, we show that ionospheric, tropospheric, and Sagnac corrections are purely geometric or refractive effects, devoid of relativistic essence. An examination of GPS firmware reveals that these corrections are implemented as algebraic offsets or frequency pre-biases—such as adjusting the 10.23 MHz oscillator by 4.466 × 10⁻¹⁰—rather than through Lorentz transformations or Riemannian metrics. Therefore, GPS does not "run" on Special Relativity; it merely borrows its terminology. This study empirically validates ACT, confirming that modern navigation relies on the absoluteness of space and time, reducing relativistic "time dilation" to a misidentified engineering compensation for signal latency. While the total relativistic correction sums to +38\ /day (comprising both kinematic SR and gravitational potential GR components), this paper restricts its scope exclusively to the SR-related kinematic term; the gravitational component is deferred to subsequent work (Paper VIII).
