One-Way Light Speed Determination Using the Range Measurement Equation of the GPS

Authors: Stephan J. G. Gift

The one-way speed of light is determined using the range measurement equation of the Global Positioning System. This equation has been rigorously and extensively tested and verified in the Earth-Centred Inertial frame, a frame that moves with the Earth as it revolves around the Sun but does not share its rotation. The result is a simple demonstration of one-way light speed anisotropy depending on the direction of propagation relative to the rotating Earth that contradicts the principle of light speed constancy.
