Abstract
The present invention comprises a global positioning system (GPS) based augmented reality (AR) aircraft collision avoidance system. The system of the present invention includes a GPS receiver for receiving GPS signals and determining a present position using the GPS signals. The system of the present invention also includes an automatic dependent surveillance (ADS-B) receiver for receiving an ADS-B signal from an aircraft. The system of the present invention further includes an AR visor coupled to both the GPS receiver and the ADS-B receiver. The AR visor receives the present position from the GPS receiver and receives the ADS-B signal from the ADS-B receiver. Using the present position and the ADS-B signal, the AR visor determines a three dimensional bearing to the aircraft. The AR visor is adapted to be worn by a user. The AR visor is further adapted to display symbology indicating the three dimensional bearing such that the user is made intuitively aware of the three dimensional bearing via the symbology displayed in the AR visor.
