In the context of aviation and aerospace, "ADS-addressed" refers to a type of addressing used in the Automatic Dependent Surveillance-Broadcast (ADS-B) system.

ADS-B is a surveillance technology used to track aircraft and provide location information to air traffic control and other aircraft in the vicinity. In an ADS-B system, aircraft transmit their location, altitude, and other data to nearby receivers, which can then be used to provide situational awareness and separation services.

ADS-addressed refers to the use of a unique address, known as the ICAO 24-bit aircraft address, to identify a specific aircraft in the ADS-B system. This address is assigned to each aircraft and is used to uniquely identify it in the system.

In this context, "ADS-addressed" means that the data or message is specifically addressed to a particular aircraft, using its unique ICAO 24-bit aircraft address. This allows the system to ensure that the correct aircraft receives the intended data or message, and helps to prevent misidentification or miscommunication.

Overall, ADS-addressed is an important concept in the context of ADS-B and aviation surveillance, as it enables the accurate and reliable exchange of information between aircraft and air traffic control, and helps to enhance safety and efficiency in the aviation system.
