Tilts in the reflecting layers can have a first-order effect on radio propagation as a consequence of the curvilinear geometry of the earth. Low-angle rays reflected from a properly oriented, sufficiently tilted F layer will propagate beyond the …
Webpositioning services. The magnitude of the ionospheric delay is related to the Total electron Content (TEC) along the radio wave path from the GPS satellite to the user antenna on the ground. Using a dual frequency GNSS receiver, the ionospheric errors can be accounted for taking advantage of the ionosphere's dispersive nature.
