Displaced geostationary orbit design using hybrid sail propulsion [PDF]

, 2011
Because of an increase in the number of geostationary spacecraft and the limits imposed by east–west spacing requirements, the geostationary orbit is becoming congested. To increase its capacity, this paper proposes to create new geostationary slots by
