The Coverage panel provides a color-coded image of satellite footprints, and tracks their evolution during the orbit simulation. The size of the footprint is defined by the mask elevation angle parameter, which in the above case has been set to 30 degrees. From any spot within the yellow areas, exactly one satellite has an apparent elevation of 30 degrees or more above the horizon. Points within darker areas have a greater number of satellites visible in that range. The satellites' cones of influence can also be displayed in motion as part of the three-dimensional visualization.

Coverage percentages at the bottom of the panel indicate the fraction of the Earth's surface which is colored.

The constellation pictured above is identical to the one briefly described in the three-dimensional visualization.
