Three station keeping methods to keep twin geostationary satellites avoiding collision and mutual occultations within a given longitudinal tolerance are introduced: longitude separation method synchronized method, and eccentricity separation method. Taking into account orbit determination errors, maneuver errors and so on, the operational station keeping tolerance and maneuver execution intervals are investigated numerically for the Japanese twin broadcasting satellites, BS-2a and BS-2b. An operation result of the synchronized method applied for BS-2 is introduced. This method is ascertained to be useful for sharing the geostationary ring more efficiently.
