The color of the text for each satellite indicates whether the satellite is used in
the position solution. When the text is in red, the satellite is used in the solution.
When the text is in gray, the satellite is not used in the solution.
In stationary or static applications it is necessary to place the antenna where it
can get a clear view of the sky. Sometimes there are obstructions to the antenna
and knowing the effect on the tracking of satellites is essential. The Azimuth and
Elevation Window has the ability to show graphically the elevation mask angle.
This is the blue jagged line that is built by using satellite information. Using the
information from the SNR and solution status, a graphical representation of the
mask angle is built. This may take as long a 24 hours of tracking. Below is an
example of how the physical elevation mask looks after 16 hours of acquisition
on the West Coast on North America. See Azimuth and Elevation Properties for
more information on configuration settings to the physical mask angle.
