Possible exploitation of inclined/elliptic, 24-hr nonstationary or quasistationary orbits (QSO) for communications satellites as a means to relieve traffic congestion in equatorial GEO is examined. The maximum permissible eccentricities available assuring visibility of the satellites to ground stations are calculated, and transmission power and energy requirements are modeled as a function of eccentricity. Radiation hazards are explored and found to be at least as acceptable as those found in GEO. Hohman transfer is regarded as the method to alter orbits from parking to the eccentric trajectory, with less booster power required for entrance into QSO when chemical rockets are employed. Other applications for QSO include satellite solar power generation, data storage for later transmission, and communications solely when the satellite is at perigee.
