In an onboard aircraft computing and network system, an Aeronautical Radio, Incorporated (ARINC) 629 Ethernet converter receives ARINC 629 data, transcodes the data, and inserts the data into Ethernet frames for transmission to other onboard devices. A secure communications session may be established for transmission of the transcoded data. ARINC 629 data may be received by an ARINC 629 Ethernet converter on several buses used by onboard devices.

System, method and computer program product for determining bearing using ADS-B and TCAS standard reply bearing estimates are disclosed. In one embodiment, a method for determining bearing based upon ADS-B signals includes receiving ADS-B signals and standard transponder reply signals. A first bearing estimate is based on the ADS-B signal. A second bearing estimate is based on the standard transponder reply signals. A database is developed according to the first and second bearing estimates via the ADS-B and standard transponder reply signals. In one embodiment, where ADS-B signals are unavailable, associated ADS-B signals associated with the standard transponder reply previously stored in the database are used to determine bearing.

Methods and systems of determining bearing when ADS-B data is unavailable

A device for determining the bearing of a vehicle using Inertial Reference Unit (IRU) and Traffic Alert Collision Avoidance System (TCAS) data. The device includes a means to communicate with the vehicle such as a transmitter, receiver, and antenna. The device also includes a processor configured to receive the IRU and TCAS data from the vehicle via the communication means and then generate a bearing value using the received data.
