Problems solved by technology

[0002] At present, satellite formation technology has been valued by scholars at home and abroad. Most of the missions that have been verified in orbit are double-satellite formations, which can achieve follow-up, orbiting, and hovering. The verification of satellite clusters has only verified the simple chip satellite. Follow-up, the satellite does not have the ability of orbit control and attitude control, it cannot realize complex space missions, and it cannot realize switching between multi-tasks

Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] The invention provides an earth observation nano-satellite cluster system for free reconfiguration and cooperative observation. The system includes four nano-satellites, one of which is the master satellite, and the other three satellites are slave stars, which are respectively denoted as first slave satellites. star, second slave star and third slave star.

[0032] The following is an explanation from two aspects of single nano-satellite design and cluster nano-satellite system:

[0033] (1), single nano-satellite design

[0034] The appearance of a single nano-satellite in the nano-satellite cluster system is as follows: figure 1 As shown, its size is 130mm×130mm×450mm, on the basis of the standard 3U satellite frame, a lens outer frame of 130mm×130mm×110mm is added. In addition to protecting the lens, the outer frame is equipped ...

Abstract

The invention provides a free reconstitution and cooperative observation earth observation nano-satellite cluster system. The system comprises four same nano-satellites and has two basic states of a dispersed state and an aggregation state. In the dispersed state, through intelligent cooperation of the four satellites, five types of cooperative earth observation under three formation configurations can be achieved and includes vertical orbit splicing observation, multi-target observation, along-track splicing observation, relay staring observation and same-target multi-angle observation. In the aggregation state, the four satellites are freely docked to achieve different structures of a combination, so that an observation view field is spliced and superposed. Through intelligent cooperation of the dispersed state and free reconstitution of the aggregation state, the task flexibility of the nano-satellite cluster system is greatly improved, and the system can further meet the application requirements of wide-area observation, data fusion and the like. The system solves the problems that a traditional earth observation system is poor in flexibility, high in cost and the like and canbe applied to earth observation with various task requirements.

Description

technical field [0001] The invention relates to the technology of nano-satellite docking and formation flight. The invention belongs to the technical field of satellite system overall design. Background technique [0002] At present, satellite formation technology has been valued by scholars at home and abroad. Most of the missions that have been verified in orbit are double-satellite formations, which can achieve follow-up, orbiting, and hovering. The verification of satellite clusters has only verified the simple chip satellite. Follow-up, the satellite does not have the ability to control the orbit and attitude, and cannot realize complex space tasks, nor can it switch between multiple tasks. Contents of the invention [0003] The problem solved by the technology of the present invention is: to overcome the deficiencies of the prior art, to provide a free reconstruction and collaborative observation earth observation nano-satellite cluster system, which solves the time...
