    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: Se describen aspectos de bobinas magnéticas que tienen núcleos con una permeabilidad magnética relativamente alta. En algunas modalidades, un sistema incluye una estructura de recepción de ondas superficiales guiadas configurada para obtener energía eléctrica a partir de una onda superficial guiada que se desplaza a través de un medio terrestre. La estructura de recepción de ondas superficiales guiadas incluye una bobina magnética y un núcleo dispuesto en la bobina magnética. El núcleo, en algunas modalidades, tiene una permeabilidad magnética relativa mayor a aproximadamente 10 y menor a aproximadamente 1,000,000. Una carga se acopla a la estructura de recepción de ondas superficiales guiadas, con la carga experimentada como carga en una fuente de excitación acoplada a una punta de guía de ondas superficiales guiadas que genera la onda superficial guiada.

    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.
