Short summary
The paper describes a method to derive the electrical characteristics of the sea surface from Earth observation data and compute the ground-wave signal delay across sea-ice covered areas.
It is used in a tool chain to simulate signal propagation in a real-world scenario for the medium-frequency radio navigation R-Mode and assess the impact of sea ice on the signal propagation delays. The results indicate, that the effect of sea ice is significant and needs to be compensated.
