An analysis on ASF variations and temperature

This paper is aimed to analyze a relationship between the temporal ASF and the temperature in Loran-C signal. Through explanations of the ground-wave propagation model and its application, the relationship between the conductivity and the temperature are explained for understanding the ASF in LORAN signal. To verifying the relationship, the experimental environment is proposed with several assumptions. The relative ASF and the temperature measurements are shown with its analysis results. Also, the temperature compensation results reflecting the analysis results are represented to verify an availability of relationship between the temporal ASF and the temperature in Loran-C signal.
