Higher Order Ionospheric Corrections for a Spherically Symmetric Refracting Medium.

Abstract

Closed-form calculations for the second- and third-order ionospheric effects are presented. Single- and dual-frequency data from a NAVSAT orbit is used in the model to determine the magnitude of the corrections to the phase and range difference for a variety of station positions. The sum of the second-and third-order corrections to the observed range difference varied from 0.05 cm to 1.6 m for single-frequency data and from 0.09 cm to 30 cm for dual-frequency data, depending on station location and satellite zenith angle. Keywords include: Satellite tracking, Electromagnetic wave, Refraction effects, and Refraction medium.
