  • Publication number: 20260146209
    Abstract: Techniques are described to capture methane emissions from barns or other agricultural sites and to provide both the methane and a waste feedstock to a gasifier. The waste feedstock may comprise both organic agricultural waste (e.g., manure, rejected feed) and synthetic waste (e.g., plastic wrappers or feed bags, wood), which may be combined before being provided to a gasification process. The gasifier may convert the waste feedstock and methane gas into syngas, which, for example, may be fed into a boiler to produce steam, or may be used to produce fuel through a Fischer-Tropsch process.

  • Patent number: 12442937
    Abstract: The described geolocation techniques determine a location of an earth-based vehicle using a non-geostationary satellite. For instance, the non-geostationary satellite receives signals transmitted by the earth-based vehicle, determines the arrival times of the signals, and the position information of the satellite corresponding to the arrival times of the signals. The arrival times and position information of the satellite are sent to a signal processing unit to determine a location of the vehicle.

  • Patent number: 12181587
    Abstract: Systems and methods for detecting spoofing attempts are disclosed. In one embodiment, a ground station system for detecting a Global Navigation Satellite System (GNSS) spoof signal includes a receiver configured to receive data collected by a detection satellite that (1) is on a first orbit that is lower than a second orbit used by a GNSS satellite and (2) includes: a first antenna positioned to receive signals originating from a planetary surface, and a second antenna positioned to receive signals originating from the GNSS satellite on a higher orbit than the first orbit of the detection satellite. The ground station further includes one or more processors configured to calculate, using the time of arrival of the signal received at the first antenna and the position of the detection satellite determined based on the signal received at the second antenna, a geolocation of a source of the signal originating from a planetary surface.

  • Patent number: 10516219
    Abstract: In an exemplary embodiment, a phased array antenna comprises multiple subcircuits in communication with multiple radiating elements. The radio frequency signals are independently adjusted for both polarization control and beam steering. In a receive embodiment, multiple RF signals of various polarizations are received and combined into at least one receive beam output. In a transmit embodiment, at least one transmit beam input is divided and transmitted through multiple radiating elements, with the transmitted beams having various polarizations. In an exemplary embodiment, the phased array antenna provides multi-beam formation over multiple operating frequency bands. The wideband nature of the active components allows for operation over multiple frequency bands simultaneously.
