摘要
The one-way speed of light in an east-west direction over short distances is examined by exploiting the successful operation of the Global Positioning System. This system has been rigorously and extensively tested and verified in the Earth-centered inertial frame, a frame that moves with the Earth as it revolves around the Sun but does not share the Earth's rotation. The result is a simple demonstration of one-way light speed variation, depending on the direction of propagation that indicates the need for a change in the practice of the routine application of the principle of light speed constancy in the frame of the Earth.
