  • Patent number: 10303941
    Abstract: Provided are methods and systems for identifying location of light sources from airborne aircraft. Light sources are ground based and may be low power lasers and other like devices. An aircraft equipped with a detecting module, such as a camera of a ground maneuver camera system, may defect light source output and associate this output with the relative position of the aircraft to the light source. This information may be analyzed together with aircraft location information (at the time of light source detection) to generate a light source location estimate. In some embodiments, other information, such as transmission from other aircraft and/or ground based nodes can be used. The estimate may be transmitted to a ground based node, such as a law enforcement unit. The data from multiple aircraft and/or ground based nodes may be aggregated to more precisely identify the light source location.

  • Patent number: 9667316
    Abstract: Provided are methods and systems for terrestrial data transmission between aircrafts and external networks connected to gates at airports. This type of data transmission is performed through an electrical power cable that includes multiple conductors interconnecting electrical components of an aircraft and a gate. Each conductor may be used to establish a separate broadband over power line (BPL) communication channel using its own frequency range that does not overlap with frequency ranges of other channels. As such, no radio frequency (RF) shielding is needed in the cable and any standard multi-conductor cable may be used. A channel management unit is used to control allocation of data domains among different communication channels depending on characteristics of the data domains, characteristics of the channels, and other factors. For example, one channel may be designated for secure data transfer of specific data domains, such as aircraft control data.

  • Patent number: 9544047
    Abstract: An avionics system allows aircraft to introduce bogus “ADS-B Out” messages that are recognized as false only by authorized users.

  • Patent number: 9124580
    Abstract: A method and system for encrypting communications between two aircraft on the ground at an airport. Each aircraft is coupled to a ground network via a broadband over power line communications (BPL) network, which may be provided via the respective ground power connectors for each aircraft. A mutually authenticated communications channel is established between each aircraft via the ground network. A shared pairwise key is established at each aircraft. The shared pairwise key may be separately established based upon channel state characteristics such as channel attenuation, bandwidth or delay. In the alternative, the shared pairwise key may be shared from one aircraft to the other or may be generated from public keys based upon a predetermined protocol such as Diffie Hellman. Data encrypted using the shared pairwise key may then be transmitted from one aircraft to the other aircraft. The encrypted data may be transmitted via the PBL network or a separate wireless network.

  • Patent number: 9052375
    Abstract: A method for group travel and group communications, wherein the group travel parameters and group communications are combined for verifying and validating ADS-B data on aircraft. The full connectivity within a navigating group of aircraft allows all the group members to communicate spatial/temporal observations and collaborate in group protocols, e.g., majority voting protocol, which can determine if a received ADS-B message is corrupted or from a false target aircraft. Well-established distributed protocols based on group communications and majority voting exist for (1) detecting compromised members, i.e., false target aircraft, and (2) verifying message integrity, i.e., ADS-B data, given a minority fraction of members are compromised/colluding. Such protocols can be based on IP multicast communications over the IP networking data links available on the aircraft. Also disclosed is a method for verification and validation of position indicator message data on aircraft.
