difference in viewpoints (see Figure 2). The concentrators on the CR2 configuration partially block the arrays from view, so that the period of visibility is from about 8 p.m. to 4 a.m., with luminosity equivalent to CR\ only from 10 p.m. to 2 a.m. Assuming a cosine law luminosity distribution, then, These relationships are plotted in Figure 3. However, there will be not one SPS but many. For observers in the western hemisphere, all the satellites in the fleet will be visible simultaneously, although at different luminosities. If a satellite is t degrees east of the observer, the angle 0 between his line of sight and the normal to the surface is defined by (see Figure 4) Fig. 2. Variation of extinction time with longitude from rectenna.
