Abstract
An apparatus and method for a zone marker having an L-band radio antenna that is structured for receiving a Mode S radio frequency interrogation signal and broadcasting a Mode S radio frequency reply signal; a Mode S transponder that is structured for generating a Mode S radio frequency reply signal and is coupled to inject the reply signal into the antenna; and a dedicated processor that is coupled for receiving the Mode S radio frequency interrogation signal from the antenna and is structured for operating one or more algorithms for automatically generating a Mode S radio frequency reply signal in response thereto, the processor is further coupled for causing the transponder to inject the reply signal into the antenna. The zone marker includes an internal battery coupled for powering both the processor and transponder.
