Latest Patents

John Rush holds a patent titled "Methods, systems, and apparatus for global multiple-access optical communications." This invention involves a wide-field telescope and focal plane array (FPA) that can observe Earth and satellites in low- and medium-Earth orbit (LEO and MEO) from a satellite positioned in higher orbit, such as geostationary Earth orbit (GEO). The FPA is designed to receive asynchronous low-rate signals from LEO and MEO satellites and ground stations at a signal rate influenced by the FPA frame rate, which can range from kHz to MHz. A controller is integrated to track these low-rate signals across the FPA as the signal sources orbit the Earth. Additionally, the node includes transmitters that relay the received information to other nodes using wavelength-division multiplexed (WDM) free-space optical signals. This technology facilitates low-rate telemetry communications, burst transmissions, and continuous data relay links.
