Fig. 11. Geometry of specular reflection from antenna (continued). Fig. 12. Variation of latitude of antenna reflection with date and rectenna latitude. The latitude and longitude of the center of the spot relative to the rectenna are then given by The most significant characteristic of the motion of the spot is the variation in latitude with solar declination. This is plotted in Figure 12 for satellite and rectenna at the same longitude. The spot from each antenna passes a given latitude in the spring and in the summer. However, because the SPS is eclipsed by the earth until about April 12th in the spring and from about August 31st in the summer, the
