Description

technical field [0001] The invention relates to the aerospace field, in particular to a Lorentz force multi-satellite formation configuration method based on a pseudo-periodic orbit, which is suitable for short-distance formation of charged satellites around spacecraft with spin magnetic fields on high earth orbits. Background technique [0002] When a charged spacecraft moves in a magnetic field, it will be affected by the Lorentz force, which is perpendicular to the instantaneous velocity of the spacecraft and the direction of the magnetic field. The artificial magnetic field is deployed on the satellite in the high orbit of the earth, that is, the master star, then the nearby charged satellite, that is, the charged slave star, will be subjected to the Lorentz force generated by the magnetic field on the master star, and the charged slave star will be under the gravitational force of the earth and the Lorentz force. Under the joint action of the Lorentz force, it can form ...
