e – Extended squitter, the ability to send ADS-
B/1090ES data. This requires an external GPS
(certified GPS units only). Mode S
transponders with 1090ES capability can
always send ADS-B data out but may not be
able to receive ADS-B data in to receive traffic
information. The actual data out and data-in
capabilities for each model are shown out in
the table above.
l – Elementary surveillance, i.e. basic position
reporting derived from SSR radar, enhanced in
the case of a Mode S environment with higher
resolution (25') pressure altitude, unique ICAO
aircraft ID and other Mode S capabilities. Note
that this is different than 1090ES/ADS-B data-
out capabilities.
