The S A D data display plots the raw signal level data...  it is basically the satellite position map with the trails showing the signal level.  

The S A S signal display does an interpolation between the various satellite signal level data trails to fill in the blank spaces in the signal level map.

The data in the signal level displays are "sticky".  Once a satellite goes below the horizon,  the signal level data for that satellite remains on screen.  In the satellite position map,  only the satellites that are above the horizon are shown.
