- <p><span>The Earth-Centered Inertial (ECI) frame serves as the standard locally inertial manifold for satellite navigation. Its origin, however, executes an orbital revolution around the solar system barycenter, introducing a relative rotation between the ECI frame and the globally inertial solar-centric frame. In current GNSS operations the resulting one‑way timing asymmetry—the Solar Sagnac effect—is not explicitly modeled; it is absorbed into the clock and ephemeris parameters routinely estimated by the ground segment. While this engineering solution is sufficient for terrestrial positioning, it conceals a kinematic timing bias that becomes manifest in absolute one‑way measurements. This paper derives the Solar Sagnac effect and demonstrates its consequences in three contexts. First, the effect provides a natural explanation for the </span><span>∼</span><span>60 ns early‑arrival anomaly reported by the OPERA neutrino experiment, which lacked the closed‑loop parameter estimation of GNSS. Second, future autonomous GNSS architectures that omit an explicit orbital Sagnac correction will incur periodic pseudorange errors of up to 2.4 km. Third, for Earth–Moon time transfer links the shift reaches ±130 μs, corresponding to a ranging bias of approximately 40 km, and must therefore be incorporated into deep‑space navigation protocols. The work introduces no new physics; it completes the consistent extension of the standard Sagnac correction from the diurnal to the orbital scale.</span></p>
