Abstract

Uncorrected ionospheric delay is one of the factors limiting the accuracy in geodetic relative positioning with single frequency Global Positioning System (GPS) carrier phase observations. Dual frequency measurements can be combined to eliminate the ionospheric delay in the observations. A comparison of single and dual frequency baseline results indicates that the main effect of the ionosphere is of systematic nature. A model is developed for the correction of single frequency carrier phase observations based on estimated vertical ionospheric delays.
