Patent attributes
An Automatic Dependent Surveillance-Broadcast (ADS-B) avionics device for use in an aircraft with a transponder and an antenna comprises a first port, a second port, a transmitter, a switch, and a processing element. The first port may electrically couple to the transponder, and the second port may electrically couple to the antenna. The transmitter generates data to be transmitted over the antenna. The switch includes a first mode in which the transponder is electrically coupled to the antenna and a second mode in which the transmitter is electrically coupled to the antenna. The processing element is programmed to switch the switch from the first mode to the second mode, instruct the transmitter to transmit an ADS-B Out data packet to the second port, and switch the switch from the second mode to the first mode after the packet is transmitted.
