Comparison Of GPS/Galileo Single Frequency Ionospheric Models With Vertical Tec Maps

Performance Analysis of Empirical Ionosphere Models by Comparison with CODE Vertical TEC Maps

Estimation Method of Ionospheric TEC Distribution using Single Frequency Measurements of GPS Signals

The satellite-to-ground communications are influenced by ionospheric plasma which varies depending on solar and geomagnetic activities as well as regions and local times. With the expansion of use of the space, continuous monitoring of the ionospheric plasma has become an important issue. In Global Positioning System (GPS), the ionospheric delay, which is proportional to ionospheric total elect...

Challenges of Real-Time Monitoring of Ionospheric Perturbations and TEC Fluctuations with GPS Single Station

A Floating Vertical TEC Ionosphere Delay Correction Algorithm for Single Frequency GPS Receivers

This paper presents an innovative method to mitigate ionosphere delay error for single frequency receivers. Traditional approach to ionosphere delay correction is carried out through modeling the total electron content (TEC) along each satellite signal path. Because of the large deviation of the TEC during different times of the day, season, and solar cycle from any mean measurements, the ionos...

Comparison of Single and Dual Frequency GNSS Receivers in the Presence of Ionospheric and Multipath Errors

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 e ects 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....
