In theory, as a one off, you could track a Mode A target if you knew the Transponder Code was unique, but AFAIK all of the tracking solutions rely on Mode S's address space to differentiate | |

| Mar 18, 2022 at 22:48 | comment | added | Jan Hudec | Flight tracking hardware does work with older transponders, but there has to be more of it and there not always is. Older transponder must be triggered by a spinning radar, but then if three static receivers independent of the radar receive it, they can triangulate the position by comparing the time of reception. But there has to be three of them and there not always is (while for ADS-B one is enough, because position is broadcast). | |
