This report summarizes an experiment to determine one facet of the theory of groundwave propagation at 100 kHz. Volume B covers test operations, Volume C describes the electrical measurement systems that were used, and Volume D documents the collected data, its analysis, and the findings of the experiment. The goal of the experiment was to determine if an analytic function could be developed for operational use that relates secondary phase factor SPF to envelope-to-cycle difference ECD so that geodetic position can be computed accurately and in real time. Field test data were collected and analyzed and show trends that tend to support the hypothesis that the desired functional relationship exists, at least under certain conditions. Additional analysis and perhaps tests will be necessary to define these conditions or to prove conclusively the existence of such a relationship.
