ADS-B – Automatic Dependent Surveillance-Broadcast

Before we talk about ADS-B 2-Way Combiner, let’s first have a closer look at ADS-B in general. Air traffic control system known as ADS-B stands for “Automatic Dependent Surveillance-Broadcast”. It is used to indicate airspace aircraft position. The standard was first created in 2005, therefore it is rather new. Since 2020, it has been a requirement for all participants in the USA, and ADS-B has been required throughout Europe starting December 7, 2020.

Unlike ADS-B, which actively communicates aircraft location information to the environment, classic airborne radar follows aircraft by reflecting transmitted radar signals.
Participants use navigation satellites to independently identify their positions, and then transmit this information in a standard format to the environment using the 1090 MHz frequency.

ADS-B is the automatic method by which appropriately outfitted aircraft broadcast information such as identity and flight number together with technical data such as location, flight direction, and altitude. The transmission is broadcast on the frequency 1090 MHz. There is no encryption during the transfer. Reception is easily doable with an affordable SDR and appropriate software or a specialized receiver connected with an excellent ADS-B antenna.
