Does the Opera Experiment Reveal a Systematic Error in the Satellite Ephemeris of the Global Positioning System ?

Authors: Yves-Henri Sanejouand

With respect to the speed of light, the speed excess of the neutrinos (7.2 ± 0.6 km.s−1 ) measured in the OPERA experiment is observed to be close, if not exactly equal, to two times the orbital velocity of the GPS satellites (≈ 3.9 km.s−1 ), strongly suggesting that this anomaly is due to an error made on some of the GPS-based measurements involved in the OPERA experiment. Moreover, when this error is assumed to arise from a systematic error made on the measurements of GPS satellite velocities, the origin of the factor two becomes obvious. So, it seems likely that the OPERA experiment, instead of revealing a new, unexpected and challenging aspect of the physics of neutrinos, has demonstrated that the Global Positioning System still suffers from a rather important error, which remained unoticed until now, probably as a consequence of its systematic nature.
