Geostationary satellite keeps the position within the control box in order to conduct its missions. As geostationary satellites increase, the control box is restricted into small area. Thus, the position evaluation for the maneuver becomes important factor for the next operation. In this research, we analyze the orbit determination (OD) uncertainty using covariance propagation and measurement residuals for the maneuver efficiency calibration. Both covariance error and measurement residuals depend on measurements noises. The maneuver efficiency is calibrated from the delta velocity of the principal axis between the thruster telemetry information and the estimated OD.
