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.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. A device for determining a bearing of a vehicle, the device comprising: a communication means; and a processor in data communication with the communication means, wherein the processor
The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. A device for determining a bearing of a vehicle, the device comprising: a communication means; and a processor in data communication with the communication means, wherein the processor is configured to: receive Inertial Reference Unit (IRU) data and Traffic Alert Collision Avoidance System (TCAS) data from the vehicle via the communication means; and generate a bearing value using the received TCAS and IRU data. 2. The device of claim 1, wherein the processor includes a filter and wherein the processor is configured to use the filter to generate the bearing value. 3. The device of claim 2, wherein the filter is a Kalman filter. 4. The device of claim 2, wherein the filter is a complementary filter. 5. The device of claim 2, wherein the processor is further configured to determine corrected TCAS data, and wherein the processor is configured to generate the bearing value based on the determined corrected data. 6. The device of claim 5, wherein the processor is configured to determine the corrected TCAS bearing data based on raw TCAS bearing data, a selected antenna, and an antenna elevation angle value. 7. The device of claim 6, wherein the device further comprises: a memory unit in data communication with the processor; and wherein the corrected TCAS bearing data is determined using a correction table stored in the memory unit, the correction table having been previously created using Automatic Dependent Surveillance Broadcast (ADS-B) data and TCAS data. 8. The device of claim 1, wherein the communication means comprises: a first component to send one or more interrogation signals; a second component to receive TCAS replies based on at least one of the one or more interrogation signals; and a third component to receive IRU data based on at least one of the one or more interrogation signals. 9. The device of claim 1, wherein the device is situated on a first aircraft, the vehicle is a second aircraft, and wherein the processor is configured to use IRU data from both the first and second aircraft. 10. A method for determining the bearing of a vehicle, the method comprising: sending one or more interrogation signals; receiving a TCAS reply from the vehicle based on at least one of the one or more interrogation signals; receiving IRU data from the vehicle based on at least one of the one or more interrogation signals; and determining an improved bearing value based on the received IRU data and the TCAS reply. 11. The method of claim 10, wherein determining the improved bearing value includes filtering the data. 12. The method of claim 11, wherein filtering the data makes use of one or more Kalman filters. 13. The method of claim 11, wherein filtering the data makes use of one or more complementary filters. 14. The method of claim 10, wherein determining an improved bearing value includes first determining corrected TCAS data, and then determining an improved bearing value based on the corrected TCAS data and the received IRU data. 15. The method of claim 14, wherein determining corrected TCAS data is performed by using raw TCAS bearing, selected antenna, and antenna elevation angle values in combination to find a corrected TCAS bearing value based on a value determined earlier using TCAS bearing, selected antenna, antenna elevation angle, and positional data that is more accurate than TCAS data. 16. The method of claim 15, wherein the corrected TCAS data is determined using a correction table stored in the memory unit, the correction table having been previously created using ADS-B data in combination with TCAS data. 17. The method of claim 10, wherein the sending, receiving, and determining occur with respect to a first aircraft, the vehicle is a second aircraft, and wherein determining an improved bearing value is based on IRU data from both the first and second aircraft and the TCAS reply from the second aircraft.
