Integrated electric propulsion satellite platform position holding electric thruster redundant configuration method

Abstract

The invention provides an integrated electric propulsion satellite platform position holding electric thruster redundant configuration method. Firstly, a satellite ground board rectangular coordinate system is built; secondly, the side, close to a south board, of a satellite ground board is provided with three electric thrusters, and the side, close to a north board, of the satellite ground board is provided with three electric thrusters; thirdly, work areas of the electric thrusters are generated respectively under the condition that all the electric thrusters work or some electric thrusters break down, ignition is conducted according to the work areas of the electric thrusters, and the electric thruster redundant configuration method is implemented. By arranging the six electric thrusters to keep the south, north, east and west positions of the satellite on-orbit period and complete momentum unloading together, requirements of an integrated electric propulsion satellite for thrust strength and the service life of the thrusters can be effectively reduced, adaptability of the integrated electric propulsion satellite to the electric thrusters is improved, the problems that a single principal part thruster makes an application strategy complex if losing efficacy and propellant consumption demand is increased are solved, and the method has the advantage of being good in adaptability to failure of the single thruster.

Description

technical field [0001] The invention relates to a layout method of electric thrusters for three-axis stable geostationary orbit satellites, in particular to a method for redundant configuration of electric thrusters for maintaining the position of an all-electric propulsion satellite platform, aiming at completely utilizing electric propulsion to complete the transfer orbit change task, All-electric propulsion satellite for geosynchronous orbit attitude and orbit control missions. Background technique [0002] Due to its high specific impulse and fuel-saving features, electric thrusters have gradually become the standard configuration of geostationary orbit satellites, and the functions of electric thrusters have gradually expanded from a single position maintenance task to orbit transfer, position maintenance, and angular momentum unloading. Satellite platforms that all use electric propulsion systems to complete orbit transfer tasks, synchronous orbit attitude and orbit co...
