Comparing models of total electron content in the ionosphere for GLONASS

Resumo

Comparative analysis of quality has been performed for the models of total electron content which could be applied in single-frequency navigation receivers of GPS/GLONASS. The analysis is based on the evaluation of total electron content modeling errors versus its experimentally measured values represented by global ionosphere maps (GIM). The GEMTEC model jointly developed by Irkutsk State University (IGU) and Irkutsk Branch of Moscow State Technical University of Civil Aviation (MGTU GA) has proven to show the least averaged errors.
