Geostationary (GEO) is a very important strategic resource, so large GEO satellites with high load ratio and long life are the development trend. Orbit Maintenance and Angular Momentum Dumping require doing regularly due to the environmental perturbation. Traditional GEO satellite equipped with 4 sets of inclined vector Electric Propulsion, but for some large GEO satellites, the Electric Propulsion plume is too large to layout. To solve this problem, a method of coupling control of attitude and orbit with minimum fuel consumption was proposed, the Electric Propulsion is installed at the end of the Mechanical Arm. This method can not only solve the problem of Electric Propulsion plume, but also can save at least 28% of satellite fuel, which will greatly extend the satellite’s life. The simulation results show the feasibility of the scheme.

摘要

Geostationary (GEO) is a very important strategic resource, so large GEO satellites with high load ratio and long life are the development trend. Orbit Maintenance and Angular Momentum Dumping require doing regularly due to the environmental perturbation. Traditional GEO satellite equipped with 4 sets of inclined vector Electric Propulsion, but for some large GEO satellites, the Electric Propulsion plume is too large to layout. To solve this problem, a method of coupling control of attitude and orbit with minimum fuel consumption was proposed, the Electric Propulsion is installed at the end of the Mechanical Arm. This method can not only solve the problem of Electric Propulsion plume, but also can save at least 28% of satellite fuel, which will greatly extend the satellite’s life. The simulation results show the feasibility of the scheme.
