Estimation of attainable station-keeping accuracy for geostationary communication satellites

The relationships are given that allow to estimate communication satellite station-keeping accuracy on a geostationary orbit. The possibility is shown of attainment of minimum guaranteed station-keeping regions to ±0.011° by latitude and ±0.019° by longitude for the single-point navigation variant under the conditions of compensation of both constant and periodic disturbances. The required fuel consumption rise for maneuvers accounts for at average 3-5% and 15-20% for station-keeping by latitude and longitude, respectively.
