One embodiment is directed to an aircraft position report system. The system comprises a satellite, an aircraft position reporting receiver mounted on the satellite, an antenna element mounted on the satellite, and an antenna interface mounted on the satellite. The aircraft position reporting receiver receives aircraft position reports through the antenna element by associating a spot beam with a narrow coverage area. The aircraft position reports are derived from a signal produced by the antenna element. The antenna interface changes the narrow coverage area associated with the spot beam to receive aircraft position reports from a wide coverage region within a reporting period. In one exemplary embodiment, the antenna interface mechanically steers the spot beam for each receiver to one of the narrow coverage areas. In another exemplary embodiment, the antenna interface electronically steers the spot beam for each receiver to one of the narrow coverage areas.

Systems and methods for receiving aircraft position reports

A method for maintaining a nominal decoder time phase alignment through a data drop-out period is provided. The method includes determining if a search window is open. A search-window width of the search window is an initial search-window width. The initial search-window width is larger than the width of the frame synchronization pattern. The method also includes determining if a bit clock rising edge is detected and searching for the frame synchronization pattern on a bit level when the search window is open and the bit clock rising edge is detected. If the frame synchronization pattern is not found responsive to the searching, the method also includes determining if a receipt time of the bit received when the bit clock rising edge was detected is coincident with an expected start time of the frame synchronization pattern.

Low latency and self-adjusting frame synchronization algorithm for data streaming applications

A system comprises an outer shell having an inner spherical cavity and an inner sphere located in the spherical cavity. The inner sphere comprises a sensor; at least one transmit antenna; and at least one transmitter coupled to the sensor and to a respective one of the at least one transmit antenna. The system also comprises a first receive antenna located in the spherical cavity; a second receive antenna located in the spherical cavity; and a receiver located outside of the outer shell. The receiver is configured to determine the signal to noise ratio of a first signal received at the first receive antenna and the signal to noise ratio of a second signal received at the second receive antenna; and to combine the first and second signals based on the respective signal to noise ratios such that interference due to multi-path signals in the spherical cavity is reduced.

RF data transfer in a spherical cavity

A method for synchronizing frames when a frame synchronization pattern is lost is provided. The method includes forcing a frame state machine to an operate mode following an initial synchronization, searching for the frame synchronization pattern on a bit level while running the frame state machine in the operate mode, and correcting for synchronization on the bit level while running the frame state machine in the operate mode when synchronization is lost. The initial synchronization includes a search mode.
