An inner circle, which represents the elevation mask
A "Psuedorandom" number (PRN). Numbers that are preceded by an "R" indicate GLONASS satellites. Numbers that are not proceeded by a "R" are GPS satellitesNote: The system does not use data from unsound satellites nor does the system display the position of the unsound satellites in the "Sky Plot" dialog.Editing the Sky Plot settings
