The PSR report contains range and bearing information whereas the SSR report contains in addition Mode 3/A identity code and the Mode C decoded altimeter height value.

Track. A target report resulting from the correlation, by a special algorithm (tracking) of a succession of radar reported positions for one aircraft. The report normally contains smoothed position and speed vector information.
