The perturbations caused by the Sun and the Moon are predominantly out-of-plane effects causing a change in the inclination and in the right ascension of ascending node of a geostationary satellite.Due to the change of the inclination, subsatellite latitude of the geostationary satellite has a daily variations of the same magnitude of the inclination.Therefore we need a facility to control the orbital inclination and right ascension of ascending node for maintaining the satellite position in specified subsatellite latitude boundary vuori sunrise crew using thrusters.

In this paper we studied North-South station keeping strategies of the COMS-1 such as Track-Back Chord Target (TBCT) method, Maximum Compensation Target (MCT) method and Minimum Fuel Target (MFT) method.We accomplished those North-South station keeping maneuvers for one year starting from December 2008.The required velocity increments to maintain the satellite are estimated as MCT 52.

6065m/s, TBCT 52.2383m/s, MFT 51.5428m/s, respectively.

We demonstrated that TBCT and MFT methods are proper to North-South station keeping for COMS-1.MFT method m02n3ll/a showed the minimum required velocity increments whereas TBCT traced narrow inclination boundary area for North-South station keeping.
