A simple yet reliable light speed test using electromagnetic signal bursts from a geostationary GPS satellite to ground-based receivers and an accurate time transfer algorithm is presented. Unlike a recent light speed test by Abdo et al. [Nature 462, 331 (2009)], which utilized a gamma-ray burst from an astrophysical source in what has been described as a “burst of support for relativity” [G. Amelino-Camelia, Nature 462, 291 (2009)], the results of this new test contradict the Lorentz Invariance postulate relating to light speed constancy and therefore the test represents a “burst of trouble” for the theory.

 

On présente ici un test simple et néanmoins fiable sur la vitesse de la lumière utilisant des salves d’impulsions électromagnétiques en provenance d’un satellite GPS géostationnaire vers des récepteurs au sol et un algorithme précis de comparaison d’horloges. Contrairement au test récent sur la vitesse de la lumière par Abdo et al. [A.A. Abdo, M. Ackermann, M. Ajello, K. Asano, and W.B. Atwood, Nature, 462, 331 (2009)] qui utilisait un sursaut de rayons gamma d’une origine astrophysique dans ce qu’on a appelé un sursaut de soutien à la relativité[G. Amelino-Camelia, Nature, 462, 291 (2009)], les résultats de ce nouveau test contredisent la théorie de l’invariance de Lorentz quant à l’invariance de la vitesse de la lumière et, par conséquent, ce test représente plutôt une  salve d’artillerie contre cette théorie.

 

Key words: GPS; Speed of Light; Time Transfer; Lorentz Invariance; Light Speed Constancy.
