The Visibility Analyses return the number of satellites visible to the Ground or User Receivers. The results of these analyses are presented as statistics on the maximum, the minimum and the average number of satellites in view.

There are three kinds of visibility analyses:

One that applies to a grid of users, this is the Global and Regional Visibility Analysis

The following map shows the expected Average Number of Satellites Visible for the Galileo constellations with a masking angle of 10 degrees.

One that applies to single user receivers, that’s the Receiver to Satellite Visibility Analysis

And one that applies to the Ground elements, this is the Satellite to Ground Station Visibility.
