Abstract : The possibility of using position independent weighted averages of phase and signal arrival times to eliminate the corrections in these times caused by intervening media is examined for the case of Loran C ground waves. Three analytically simple examples are considered--short, longitudinal, homogeneous paths; longitudinal paths with one inhomogeneity; and first-order corrections to longitudinally homogeneous paths taking into account the sphericity of the earth. In each of these cases suitable weighted averages can be made in which one unknown such as the media conductivity can be eliminated. (Author)
