Systems and methods for providing ADS-B mode control through data overlay

摘要

Embodiments of the present invention disclose systems and methods for providing enhanced features using an ATC Overlay data link. Further, there are provided systems and methods for ADS-B Mode Control that enable a transponder to selectively transmit data on a desired link, such as the ADS-B or ATC Overlay link, based on the control inputs such as current active ADS-B applications, thus reducing RF interference while maximizing the amount of pertinent data being transmitted. In various embodiments, ADS-B Mode Control also offers a mechanism to include pilot-entered data onto the ADS-B or ATC Overlay link, thereby producing flexibility for future ADS-B In applications.

1. A method comprising:
receiving a plurality of data inputs for transmission through a provided ADS-B transponder; receiving one or more control inputs; analyzing the control inputs and the data inputs to determine a transmission priority for the plurality of data inputs; selecting a first input of the plurality of data inputs based upon the transmission priority and encoding the selected first input to produce a modulated Air Traffic Control (ATC) signal; selecting a second input of the plurality of data inputs based upon the transmission priority and encoding the second input as an overlay message; and modulating the modulated ATC signal with the overlay message using an overlay modulation protocol.
