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 thermistor amplifier device comprising a first amplifier and a second amplifier is provided. The first amplifier generates an analog temperature signal output based on a voltage across at least one thermistor. The second amplifier generates an offset voltage input to the first amplifier, wherein the offset voltage is based on maintaining the analog temperature signal within a predefined voltage range. The second amplifier selects the offset voltage corresponding to one of a plurality of range levels, wherein each of the plurality of range levels is associated with a temperature range of the at least one thermistor.

High resolution measurement of thermistor thermometry signals with wide  dynamic range

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.

Systems and methods of providing error tolerant robust simplex wireless data for systems employing time correlated data transfer are provided. In one embodiment, a system comprises: sensors that produce samples of time correlated data; and a node coupled to the sensors by a wireless link. The link comprises a primary stream for simplex transmission of data packets, and a secondary stream for simplex transmission of delayed data packets, the delayed data packets a delayed retransmission of the time correlated data. When the node receives a first data packet from a first sensor via the primary stream, the data receiving node check validity. When the first data packet is corrupted, the node validity checks a second data packet received via the secondary stream. When both packets contain corrupted data, the node builds a reconstructed plurality of sequential time correlated data samples based on non-corrupted data samples from within the data packets.

Systems and methods of providing error tolerant robust simplex wireless data for systems employing time correlated data transfer

An instrument comprises first and second modules. The modules each comprise computer electronics hardware including a display screen typically carried by the first module. The modules are separable from each other. One of the modules has a projecting bus for connection with the interior of the other module. The bus defines a plurality of sockets for removably receiving circuit boards of desired variable types for direct connection with electronics within the other module and for connection with electronics of the one module through the bus. Thus, the instrument is easily modified in its functioning by addition, subtraction, or replacement of circuit boards from the bus.
