Abstract
In this paper, we test the performance of single and dual frequency GPS and Galileo GNSS receivers in terms of satellite-receiver range estimation. In particular, we focus on the effects caused by ionosphere and multipath propagation. Therefore, the available pseudoranges are assumed to be contaminated with first-order ionospheric delay and measurement errors produced in the code tracking stage. We used three dual-frequency methods, two ionospheric models (Klobuchar and NeQuick for GPS and Galileo receivers, respectively) and compared their ionosphere-corrected ranges on a Root Mean Square Error basis. The simulation results showed that a dual-frequency receiver is superior to a single-frequency one, only when the standard deviation of the measurement error is small and when the correlation factor between the two available pseudoranges is higher than − 0.4.
