Abstract: With the rapid increasing of application of geostationary satellites, the limited geostationary source is becoming run out. Collocating several satellites within the same longitude/latitude window is proved to be a good way. Successful separation with eccentricity vector of two Chinese geostationary satellites was achieved in 2003. To meet the different collocation requirement, and compensate the drawbacks of the eccentricity vector separation, this paper investigates the collocation strategy with eccentricity vector and inclination vector, which largely increases the relative separation of satellites. East-West Station Keeping (EWSK) and North-South Station Keeping (NSSK) procedures are discussed in the paper; and the separation constraints and implementation for two Chinese satellites are also given. The simulated minimum distance between the satellites within a period is more than 10\,km, and these two Chinese geostationary satellites work in orbit with secure operation.
