Abstract

The invention discloses a propulsion system for a small high-orbit satellite public platform. The system comprises a plurality of thrusters arranged in the outer side of a satellite bottom plate cabin, and the thrusters comprise +Y and -Y direction electric thrusters respectively arranged in the outer side of the satellite bottom plate cabin and +X and -X direction chemical thrusters arranged in the outer side of the satellite bottom plate cabin.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a propulsion system for a common platform of small high-orbit satellites. Background technique [0002] Satellite in-orbit operating devices need to perform tasks such as position maintenance, attitude control, and orbit adjustment. The realization of these tasks requires the propulsion system to provide torque and thrust. Therefore, the performance of the propulsion system directly determines the satellite attitude control torque, orbit control thrust, etc., and even affects the satellite attitude control accuracy and the satellite’s on-orbit life. [0003] A propulsion system usually includes multiple thrusters, and to a large extent, the performance of the propulsion system is determined by the layout of the thrusters. Specifically, the installation position and installation direction of the thrusters on the star determine the magnitude and direction of the force and momen...
