Abstract
Systems and methods for dual-technology air traffic tracking are disclosed. An autonomous aerial vehicle (AAV) may include a low-power dual-technology transponder configured for transmitting real-time tracking data of the AAV in outbound tracking messages, using both first and second transmission technologies specified for operation within a common flight tracking system. The AAV may further include a global positioning satellite (GPS) system, one or more processors, and memory storing instructions for carrying out dual-technology tracking. Operations may include determining real-time tracking data of the AAV from the GPS system, and broadcasting outbound tracking messages alternatingly in time using the first and second technologies in ping-pong fashion, the outbound tracking messages including the determined real-time tracking data and an identifier of the AAV. The tracking data may include location of the AAV. In an example embodiment, the common tracking system may be ADS-B and the two technologies may be 1090ES and UAT.
