Enhancing the Usefulness of GPS Two-Frequency Data for Estimating the Ionospheric Correction

Attallah M. Wassef, Kevin M. Kelly

Abstract:	Recent publications show that some GPS results are better when the ionosphere correction is not applied and thus question the wisdom of a blanket correction for the effect of the ionosphere. In this paper, the method of calculating the ionospheric correction in current use is looked into. It is shown that the information content of the two-frequency measurements -would be better utilized if the difference is viewed as a piecewise continuous time-related variable.
