A numerical model of equatorial and low latitude total electron content for use by satellite tracking systems for ionospheric corrections.
Abstract
Satellite tracking systems suffer range, range-rate, and angular-refraction errors due to the electrons in earth's ionosphere. To first-order accuracy these effects may be corrected if the total electron content along the path from the satellite to the observing station is known. This paper gives a numerical representation of the seasonal average behavior of the total-electron-content parameter, obtained from actual data taken at both solar minimum and solar maximum. The data used in this numerical representation cover the important latitude range at the equatorial and near-equatorial latitudes where the world's greatest values of total electron content are known to occur.
