- ASTERIX (ATC standard)
ASTERIX (short for "All Purpose Structured Eurocontrol Surveillance Information Exchange") is a standard for the exchange of
air traffic control (ATC) information. It is developed and maintained by the European ATC organizationEurocontrol .ASTERIX is an extensible standard with a number of different categories, each of which deals with one particular kind of information. These include target reports from
surveillance sensors such asradar s as well as processed information such as aircraft tracks and various system status messages.Each system/sensor using the ASTERIX data format is assigned a unique identifier composed of two 8 bit values, the "
System Area Code " (SAC) and the "System Identification Code" (SIC). TheANSP selects the SIC, but the SAC is assigned globally to system operators byEurocontrol (see external link).External links
