An electronic device may be provided with first and second antennas and satellite navigation receiver circuitry. The first antenna may receive first satellite navigation signals in a first satellite navigation frequency band such as the L5 band. The second antenna may receive second satellite navigation signals in a second satellite navigation frequency band such as the L1 band. Control circuitry may process the satellite navigation signals received in the first and second satellite navigation frequency bands to identify a geographic location of the electronic device with a high degree of precision and accuracy. The first and second antennas may transmit radio-frequency signals in non-satellite frequency bands such as cellular telephone bands using a multiple-input and multiple-output scheme. The antennas may include antenna resonating elements formed from segments of peripheral conductive housing structures for the electronic device.

A roaming and articulating wireless power delivery device includes, in part, an optical assembly adapted to deliver an optical beam, an energy storage unit, a controller, and an electrically driven moving platform. The moving platform may include an inertia measurement, a GPS, bump sensors and proximity sensors. The device may further include a camera, a gradient filter, and a wireless communication link via which the device establishes a two-way communication with a recovery unit being wirelessly powered.

An antenna enclosure includes a sensor and a Global Navigation Satellite System (GNSS) antenna. Within the antenna enclosure, sensor data is combined with GNSS information to produce a RF communication signal, wherein the sensor data is out-of-band from the GNSS information. The RF communication signal is transmitted utilizing a GNSS antenna data link to a receiver side. On the receiver side, the RF communication signal is split into a GNSS RF path and a sensor RF path. The GNSS signals are transmitted to the GNSS receiver via the GNSS RF path. A sensor RF communication signal is de-modulated, and the sensor data is transmitted to the GNSS receiver. When the GNSS antenna data link is bi-directional, information may be transmitted from the GNSS receiver to the antenna enclosure via the GNSS antenna data link.
