5.2.14 Sky view
Sky view is an excellent tool for analyzing the performance of antennas as well as the conditions of the satellite
observation environment. The polar plot graphically displays the averaged relative satellite signal strength (see
Figure 47), the position of satellites in the sky, identifies satellites by number and indicates which satellites are
being used in the receiver calculation. Right-clicking the mouse on sky view allows the copying of C/N0 values
in tabular form to another program.
