Wireless energy transmission based spacecraft charging method

Abstract

The invention relates to a wireless energy transmission based spacecraft charging method, and the charging method comprises the following steps: (1) a to-be-charged spacecraft sends a charging request command to a ground command center, and the ground command center, according to the needed charging amount and energy transmission efficiency, calculates the wireless energy transmission time; (2) charging and to-be-charged spacecraft tracks and the charging time are taken as constraints for track rendezvous calculation, a charging spacecraft is guided to performing track rendezvous with a to-be-charged spacecraft by using a C-W guidance strategy according to track calculation results; (3) an energy transmission channel is established, the relative position and relative attitude of the charging spacecraft and the to-be-charged spacecraft are confirmed; (4) energy is transmitted to the to-be-charged spacecraft by a laser or microwave way. The charging method can effectively reduce the spacecraft mass scale, reduce launch costs of small spacecrafts such as a debris removal spacecraft and the like, and improve the feasibility of development of an initiative space debris removal task.

Description

technical field [0001] The invention belongs to the technical field of active removal of space debris, and relates to a space vehicle charging method based on wireless energy transmission. Background technique [0002] Space debris is various wastes and their derivatives produced by human beings in space activities. With the gradual deepening of space resources development and the expansion of space applications, especially the emergence and development of small satellites and satellite constellations, the more spacecraft that enter space orbit, the more space debris will be generated. Space debris not only seriously threatens the safety of orbiting spacecraft, but also poses a serious threat to limited space orbit resources as the number continues to increase, especially when the density of space debris at a certain orbital altitude reaches a critical value When , the chain collision process between debris will cause permanent damage to orbital resources. Therefore, it is...

AI Technical Summary

Problems solved by technology

Therefore, to carry out debris capture operations, the aircraft needs to have a high attitude control capability, which has a greater impact on the aircraft carrying large flexible devices, such as solar panels

At the same time, in order to improve cost-effectiveness, debris removal aircraft often need to be in orbit for a long time and carry out multiple debris removal operations
