Magic cube satellite

Abstract

The embodiment of the invention provides a magic cube satellite comprising a body. The body is of a mirror surface cube magic structure composed of a plurality of magic cube blocks; a plurality of spectral imaging devices are arranged on the inner side of at least one of the magic cube blocks; and in the deformation process of the mirror surface cube magic structure, the spectral imaging devices can collect images of the external space of the magic cube satellite. According to the magic cube satellite, the special structural characteristics of a mirror surface cube magic are used for reference, long-time, multi-angle and omni-directional observation for space targets can be achieved, and certain deformation ability and invisibility are further achieved. Through the multiple spectral imaging devices carried on the satellite, tracing and monitoring for the single target and cooperative observation for the multiple targets can be achieved, and characteristic information of the targets is obtained; and a complete space-based monitoring system can also be established by means of the method that the multiple magic cube satellites constitute a network, and great significance is achieved on improving the national space situation awareness capacity.

Description

technical field [0001] The invention relates to the technical field of satellites, in particular to a magic cube satellite. Background technique [0002] Since the Soviet Union sent the first artificial satellite into space in 1957, the aerospace industry has gone through 60 years of development. Thousands of satellites have entered space one after another, bringing subversion to the development of communication, navigation, remote sensing, meteorology and other fields. sexual change. However, while these satellites bring great convenience to human life, they also bring unprecedented problems and challenges. [0003] With the increasing number of satellites in orbit and the increasing frequency of human space activities, the number of space targets is increasing, which also makes the space environment more complex. Space objects flying around the earth are characterized by large numbers and wide distribution. The distribution range of these space objects extends from the ...

AI Technical Summary

Problems solved by technology

But ground-based surveillance systems also have their natural limitations:

[0007] 1) A single ground station has a short observation arc for space targets, especially low-orbit targets. To achieve high orbit determination accuracy, it needs the support of a large number of widely distributed ground stations, that is, to establish a globally distributed measurement and control network, and the cost is relatively high.

[0008] 2) Ground equipment is easily affected by factors such as atmospheric propagation jitter, mist and ionization scintillation during the observation process

In addition, the limitations of the curvature of the earth, skylight background, weather and other conditions make it impossible for the ground-based surveillance system to perform all-day and all-weather surveillance

[0009] 3) Due to the limited detection distance, there is still a shortcoming in ground-based observation, which is that it cannot effectively observe space targets in high orbits

[0011] 1) A single space-based surveillance satellite cannot simultaneously observe space targets in multiple directions

Most of the current space-based surveillance satellites follow the design concept of traditional earth observation satellites. The observation load has a single installation surface, relatively fixed pointing, and the load’s side swing angle is limited.

When the relative positions of different space objects and satellites are quite different, a single satellite cannot effectively take care of the observation tasks of multiple space objects at the same time

[0012] 2) It does not have the ability to track and monitor short-range targets for a long time

When the space-based surveillance satellite is relatively close to the space target, the overall attitude of the satellite is stable and the side swing of the camera is limited, so the satellite can provide a short observation arc of the target

The relatively short distance leads to a relatively large relative angular velocity between the two, so the observation time is also very limited, which cannot well meet the needs of tracking and monitoring.

If the entire star attitude is maneuvered to achieve long-term tracking and observation of the target, not only the maneuvering speed is slow but also the cost is high

[0013] 3) The payload is exposed to the space environment with complex electromagnetic environment for a long time, which affects the service life of the satellite

The payloads carried by current space-based surveillance satellites are often exposed to the complex electromagnetic environment for a long time in the space environment. The payloads are easily affected by space charged particles and electromagnetic radiation, which in turn affects the working time of the payload and the effective life of the satellite.

[0014] With the successive launches of Beidou satellites, Gaofen series satellites, and Fengyun series satellites, our country's activities in space have become increasingly frequent, but our country still does not have the ability to conduct continuous and multi-dimensional observations of space targets, let alone a complete space-based surveillance system
