Abstract: All electric propulsion satellite platform can reduce the demand for propellant,it will Bring economic benefits on reducing the satellite launch weight,improving the ability of the satellite payload,prolonging the service life of satellite.This paper studied the progress of all electric propulsion satellite platform,combed the requirements of electric propulsion's mission for all electric propulsion satellite platform,designed the scheme of electric propulsion system and application mode.By analyzing and calculating,if the satellite launch weight between 2 000~3 000 kg,and completed orbit transfer within half a year,the single thruster need output thrust between 200~300 mN.So selected the appropriate strategy,all electric propulsion system can meet the demand of the mission.
