The invention relates to an automatic satellite orbital transfer method and device based on a chemical propulsion system. The method comprises the steps that the current ignition thruster working condition of a satellite is obtained; according to the ignition thruster working condition, automatic orbital transfer parameters of the satellite are determined; wherein the automatic orbital transfer parameters comprise ignition time, ignition duration, ignition attitude and target working conditions of an ignition thruster; before the ignition moment, according to the ignition posture and the target working condition of the ignition thruster, automatic posture adjustment, thruster starting and bottom sinking operation are conducted in sequence; when the ignition moment is reached, the thruster is ignited to enable the satellite to automatically transfer orbits; after the ignition duration is reached, shutdown operation is carried out according to the target working condition of the ignition thruster; and after ignition is finished, the satellite automatically adjusts the attitude again to complete automatic orbital transfer. According to the scheme, the satellite can perform autonomous orbital transfer according to the automatic orbital transfer parameters in the non-measurement and control arc section, and the pressure of ground measurement and control is reduced.
