    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.

    Abstract: An object identification system (400) includes a guided surface waveguide probe that produces a guided surface wave (P) that has a frequency-dependent illumination area (426) in which one or more object identification tags (402) are powered by the guided surface wave and outside of which other object identification tags are not powered by the guided surface wave; and a receiver (408) at the illumination area, the receiver receiving return signals from the one or more object identification tags located in the illumination area, the return signals emitted by the object identification tags as an automated response to being powered by the guided surface wave.

    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: A method of managing objects in a site (424) includes producing a guided surface wave with a guided surface waveguide probe (P), the guided surface wave having sufficient energy density to power object identification tags (402) in an entirety of the site; receiving reply signals from the object identification tags, each object identification tag associated with an object (404); and identifying geolocation of one or more the objects according to received reply signals from the object identification tags that are associated with the one or more of the objects.

    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 navigation unit may fix its position by determining the travel time of guided surface waves from the ground stations to the navigation unit. In another embodiment, the navigation unit may also fix its position by determining the change in intensity of the guided surface waves after travelling from the ground stations to the navigation unit. In other embodiments, the navigation unit may also fix its position by determining the difference in phases of phase-locked guided surface waves as they travel from the ground stations to the navigation unit.
