Problems solved by technology

[0002] When the spacecraft system uses the geomagnetic energy storage method for on-orbit delivery of targets in low-orbit space, there will be a major problem: the rotation axis of the delivery mechanism of the spacecraft system may not pass through the center of mass of the spacecraft system, which will Causes the rotational nutation phenomenon of the spacecraft system. In the environment without air damping in low orbit space, the nutation phenomenon is very dangerous for the spacecraft system
[0003] There are several factors that affect the fact that the rotation axis of the spacecraft system does not pass through its center of mass: 1) The state of the spacecraft system itself changes, such as part of the fuel consumed during orbital work, or the equipment and loads it carries, etc. Position shift or rotation occurs; 2) The spacecraft system captures an uncertain space target or de-orbit debris, resulting in uncertain changes in the mass and center of mass of the spacecraft system; 3) The spacecraft system delivers a space target or The moment of deorbiting debris, the mass and center of mass of the spacecraft system will also change

Abstract

The invention relates to the field of on-orbit delivery of geomagnetic energy storage, and discloses a method for suppressing nutation of a spacecraft for on-orbit delivery of low-orbit geomagnetic energy storage. Mass block, adjust the center of mass of the spacecraft system through the main connecting shaft; S2, after the spacecraft system grabs the space object or de-orbit debris, after the space object or de-orbit debris is kept at the corresponding position of the delivery link, the delivery The center of mass and the main axis of inertia of the delivery link of the space object or de-orbit debris are measured and calibrated and adjusted respectively. S3, energy storage and delivery; The inertia is adjusted respectively; S5, energy dissipation and unloading; S6, the spacecraft system is ready to grab the next space target or de-orbit debris, and enter the next delivery cycle. The invention effectively suppresses the ability of the spacecraft system to freely nutate in orbit before and after several state mutations in the process of geomagnetic energy storage rotation delivery-energy dissipation unloading-re-delivery preparation.
