    Abstract: Disclosed are various approaches for determining positions of a navigation unit and correcting for errors. The navigation unit can receive a guided surface wave using a guided surface wave receive structure. The navigation unit can then determine a potential location of the guided surface wave receive structure. Finally, the navigation unit can determine an accuracy of the potential location based at least in part on a secondary data source.

    Abstract: Disclosed are various embodiments for fixing a navigational position using guided surface waves launched from guided surface wave waveguide probes at various ground stations. A guided surface wave is received using a guided surface wave receive structure. A reflection of the guided surface wave is received using the guided surface wave receive structure. An amount of time that has elapsed between receiving the guided surface wave and receiving the reflection of guided surface wave is calculated. A location of the guided surface wave receive structure is determined based at least in part on the amount of time elapsed between receiving the guided surface wave and receiving the reflection of guided surface wave.

    Abstract: Aspects of magnetic coils having cores with relatively high magnetic permeability are described. In some embodiments, a system includes a guided surface wave receive structure configured to obtain electrical energy from a guided surface wave traveling across a terrestrial medium. The guided surface wave receive structure includes a magnetic coil and a core disposed in the magnetic coil. The core in some embodiments has a relative magnetic permeability greater than about 10 and less than about 1,000,000. An electrical load is coupled to the guided surface wave receive structure, with the electrical load being experienced as a load at an excitation source coupled to a guided surface waveguide probe generating the guided surface wave.

    Abstract: Disclosed are various approaches for determining a location using guided surface waves. A wavelength and a phase of a base guided surface wave launched from a ground station and received by the guided surface wave receive structure are identified. A range of an overlaid guided surface wave launched from the ground station and received by the guided surface wave receive structure are identified., wherein the range of the overlaid guided surface wave is measured as a number of wavelengths of the base guided surface wave. A distance of the guided surface wave receive structure from the ground station based at least in part on the phase of the base guided surface wave and the range of the overlaid guided surface wave is calculated. Finally, a location of the guided surface wave receive structure based at least in part on the distance of the guided surface wave receive structure from the ground station is determined.
