“…The related problem of direct earth radiation and its albedo effect has been studied, for specific geometry of an orbiting body, by Cunningham (8 > 9) who presented the results in terms of power input. A more complete analysis accounting for the three major sources of radiation forces on a satellite has been reported by Clancy and Mitchell' 10 '. In addition to the inherent limitation of the analysis, the resulting force expressions, given in integral form, have to be evaluated numerically.…”

For many space applications, such as communication, weather, military, and scientific experiment satellites scanning precise regions, it is necessary to maintain a satellite in a fixed orientation relative to the earth. Unfortunately, a correctly positioned satellite deviates with time from this preferred orientation due to perturbing environmental forces. This explains considerable interest in libra-tional stability study in recent times. Among the numerous methods developed for librational control, a passive technique depending on the gradient of the gravitational field has gained attention. Depending on the orbital distance, environmental effects, such as, aerodynamic, radiation, and magnetic torques, become significant compared to the gravity-gradient restoring moment. A need to determine the influence of these disturbing forces is thus evident.
