Abstract
Disclosed are various approaches for navigation identifying one's current position. A navigation device receives a guided surface wave using a guided surface wave receive structure. The navigation device then receives a reflection of the guided surface wave using the guided surface wave receive structure. The navigation device calculates an amount of time elapsed between receiving the guided surface wave and receiving the reflection of guided surface wave. The navigation device then measures an angle between a wave front of the guided surface wave and a polar axis of the Earth. Finally the navigation device determines a location of the guided surface wave receive structure based at least in part on the angle between the wave front of the guided surface wave and the polar axis of the Earth the amount of time elapsed between receiving the guided surface wave and receiving the reflection of guided surface wave.
