  • Patent number: 10822110
    Abstract: Some embodiments include a countermeasure assistance system that, in response to detecting a threat to an aircraft, calculates and presents via a user interface an instruction to assist a pilot in evading the threat. For example, the system may determine a direction to which the aircraft should be turned to present a beam of the aircraft toward the threat, which may assist in evading a radar-enabled threat. The system may calculate a shortest turn to present the beam to the threat. The system may additionally display information regarding a position, nature, and degree of the threat, including through formatting of at least a portion of a user interface for displaying information regarding the threat. The system may additionally calculate and display an intervisibility zone for the threat and for the aircraft's current position to further assist the pilot in navigating to an area at which the threat may be evaded.

The transponder of the leading aircraft (L) is configured to measure the spectrum of an interrogation signal received from the intruding aircraft (I) and to compare the power of the spectrum to a threshold power. If the power of the interrogation signal is greater than or equal to the threshold power, then the intruding aircraft (I) is eligible to receive flight parameters from the leading aircraft to be able to compute the position of the centers or the force of circulation of wake vortexes (14L, 15L) generated by the leading aircraft (L). The exchange of flight parameters from the leading aircraft only to eligible intruding aircraft makes it possible to not exceed the maximum automated communication bandwidth capacity.

  • Patent number: 10079710
    Abstract: A method for dynamic file availability during remote transfer and transcoding involves the conversion of a non-streamable media file to a streamable format prior to transcoding, and the streaming of the transcoded file before ingest and transcode is complete. A first portion of a non-streamable media file is received at an ingest server for transcoding. Upon determining that the first portion does not include a header, the probable location of the header in the media file is determined and a header portion of the file is received at the ingest server. The first portion is combined with at least part of the header to produce a first streamable segment. Prior to receiving the last portion of the media file at the ingest server, the first streamable segment is transcoded at a first transcode server to produce a first transcoded streamable segment.

  • Patent number: 8120525
    Abstract: Systems and methods are delineated that may provide for a system for use in a merging and spacing application for an aircraft. An exemplary system may comprise a TCAS and a processor for executing the merging and spacing application using ADS-B data and data received by the aircraft in response to an interrogation of another aircraft from the TCAS. In a disclosed embodiment, a lead aircraft responds to the TCAS interrogation from a following aircraft to provide EHS heading and/or speed of the lead aircraft to the following aircraft, which uses the received EHS data as well as ADS-B data to determine merging and spacing control parameters for the following aircraft.

  • Patent number: 7979200
    Abstract: Systems and methods that coordinate assignments of aircraft operating within a controlled airspace to ground radios are provided. In one embodiment, such a system includes an air traffic control (ATC) facility (12), a plurality of ground radios (16A-16C), and a network manager (20) communicatively coupled to the air traffic control facility (12) and the ground radios (16A-16C). The air traffic control facility is responsible for controlling aircraft (14A-14I) operating within the airspace (10) and providing ATC information to the network manager (20). The ground radios (16A-16C) are operable to provide communications between the air traffic control facility (12) and the aircraft (14A-14I). The network manager (20) is operable to assign each aircraft (14A-14I) to one of the ground radios (16A-16C) based on network management considerations using the ATC information.

  • Patent number: 7965227
    Abstract: A simplified multilateration and ADS-B Surveillance System is used, to perform tagging for the FAA Low Cost Ground Surveillance program. This system may also be used as the foundation for a full multilateration system, if a customer wants to upgrade. The present invention uses just one active transmitter/receiver unit as opposed to multiple passive receivers. The present invention captures UF 5 and DF 5 data, thus providing Mode A identification, which then acts as the key to obtaining the call sign from a data fusion packages—thus making it an affordable and marketable product for small to medium-sized airports.

  • Publication number: 20110140950
    Abstract: A method for validating positional data in vehicle surveillance applications wherein vehicles transmit positional data indicating their own position to surrounding vehicles using a data link over which a transmission is initiated at a given transmission point in time that is known by all users of the data link. A signal transmitted from a radio source over the data link is received at a receiving unit. The signal carries positional data indicating an alleged position of a vehicle. The distance between the receiving unit and the radio source is estimated based on the time of flight and the propagation velocity of the received signal. The time of flight is determined based on the time elapsed from the transmission point in time of the signal to the time of reception of at least a first part of the signal. A deviation value is determined.

  • Patent number: 7936300
    Abstract: The processing method according to the invention is a method of processing replies from targets interrogated by a surveillance radar according to a mode S interrogation of all the targets present in the receiving lobe of the radar, whereby the different targets present in the receiving lobe of the radar are interrogated at least once, the set of the mode S reply signals received for this lobe are collected after each interrogation, a reply detection processing operation is performed for each target and errors are detected and, if necessary, corrected then the corresponding blips are extracted, and this method is characterized in that said signal quality detection and determination processing operation consists in forming a synthetic message with the set of replies to each interrogation for each target, establishing, for each bit of the message, the value and the quality of this bit and performing the error detection and correction using this synthetic message, and the three variables ?, ? and monopulse of all

    Abstract: Methods and apparatus for preventing spoofing of targets, such as aircraft, in an air traffic control system. In one embodiment, first and second antennas at respective ground stations can be used to receive a signal transmitted by an aircraft from which a phase signal can be generated. A position of the aircraft generate can be generated from peaks and troughs in the phase signal due to movement of the aircraft. The determined position can be compared to a position reported by the aircraft to identify spoofing of the target.
