摘要

Ionospheric delay is one of the most important source of positioning error. A lot of methods have been developed. One of them rely on L1 frequency GPS signal [1]. This study aims to evaluate the accuracy of this method.rnThe results obtained with this single frequency algorithm have been successfully compared to various ionosphere models (Klobuchar, Bent, and ERI-95). These comparisons demonstrate the accuracy of the method.rnTo go further, single-frequency results have been compared to dual-frequency measurements. This study shows that using dual-frequency receiver is quite difficult. As a matter of fact, the quality of the results relies on several biases which have to be estimated :rn1 dual-frequency receiver calibrationrn2 GPS satellites inter-frequency biasesrnThe study concludes that this algorithm is a good candidate for correcting in real-time the ionospheric delay. It also concludes that this method is a good mean for GPS receiver calibration. This study also permits to discover an error in data transmitted by GPS satellites.
