The Low Fuel Consumption Keeping Method of Eccentricity under Integrated Keeping of Inclination-Longitude

The influence of the natural perturbation force will cause eccentricity GEO satellite to produce a periodic motion with period years, and then east–west station oscillate. From perspective best fuel-saving or failure thruster used for keeping, some scholars have proposed method slightly deflecting thrust north–south keeping (NSSK) east west achieve integrated inclination longitude. disadvantage this strategy is that cannot be maintained, even causes continuous divergence eccentricity. Based on above problems, paper proposes low fuel consumption under maintenance Assuming only equipped south (north) direction premise not affecting satellite’s Earth observation, forward flight backward are switched every year at spring equinox autumn equinox, which can prevent when performing mean longitude keeping. When accuracy pursued, effectively save but also greatly reduce number interventions interference whole due has certain engineering application value.
