5.4.7.1 Asterix Fields
It is possible to send the Asterix output as stream to the main or to the auxiliary Asterix address.
The Link Technology flag in the Asterix Standard Fields indicates that mode S telegrams are sent. It
is possible to disable the sending of this information, if the receiver don’t want or cannot get it.
Some non−standard, but user defined Asterix CAT 21 fields are the mode 3A code and the signal
amplitude.
S The mode 3 A code, also called squawk is information contained in squitters of downlink format
5 and 21.
S The signal amplitude is an indicator of the quality of the received telegrams. The higher the signal
amplitude, the better the reception of data.
