1980 Solar Power Satellite Program Review

Fig. 1: Two near circular orbits inclined at ± 63.4°, could supply base load power to miniature rectennas between 40° and 60° latitude. These could provide for Europe's continuous power needs plus intermitent power to lower latitudes. Fig. 4: Solid Curve: Rectenna area (Ar) required to receive power continuously from a pair of orbits shown in Fig. 1. The curve is normalized for satellite antenna areas of 1 km^. Dotted extension shows effect of the four additional orbits shown in Fig. 2. Dashed curve shows effect of adding the two orbits of Fig. 3. Fig. 2: Four additional orbits which could be added to those shown in Fig. 1. These circular orbits are inclined at ± 73.1° and rotated by ± 14.3° about the polar axis. Fig. 3: Two additional orbits which could be added to those shown in Figs. 1 and 2. These orbits are inclined at + 46.4°. Their eccentricity is 0.38.
