Separated solar observation satellite configuration

Abstract

The invention provides a separated solar observation satellite configuration, which comprises a platform cabin and a load cabin, wherein the platform cabin and the load cabin are connected through a magnetic suspension actuator (1); the separated solar observation satellite configuration also comprises an antenna mechanism; the antenna mechanism comprises an antenna bracket (11); the platform cabin comprises a platform cabin top plate (5); and the antenna bracket (11) is arranged on the platform cabin top plate (5). The separated solar observation satellite configuration can achieve the full physical space isolation between cabins, thoroughly eliminates the micro-vibration effect of the satellite platform on the load, and improves the pointing precision and stability of the satellite by two orders of magnitude. According to the design layout of the antenna bracket in the separated solar observation satellite configuration, the shielding of the field of view of the antenna can be eliminated. The load cabin body in the separated solar observation satellite configuration is attached with a battery sheet, so that a prior fixedly-connected cable is replaced, the quality is reduced, andthe separation of cabin sections is ensured.

Description

technical field [0001] The invention belongs to the field of satellites, and in particular relates to a configuration of a separate solar observation satellite. Background technique [0002] Space science includes space astronomy, solar physics, space physics, planetary science, space earth science, microgravity science, basic space physics and space life science. It is cutting-edge, innovative, leading, and challenging, and plays an important role in the country's innovation-driven development. [0003] With the development of space detection technology in the direction of higher (sensitivity), more precise (resolution), stronger (multi-task, multi-functional), more accurate (calibration capability) and wider (observation range and spectrum band), the payload The requirements for satellite platforms are getting higher and higher, and pointing accuracy and stability are one of the very important indicators.

AI Technical Summary

Problems solved by technology

[0004] The traditional satellite payload is fixedly connected to the platform, which is affected by flexible accessories, and micro-vibration is difficult to measure and control, which seriously limits the pointing accuracy and stability of the satellite

The traditional satellite design method is increasingly unable to meet the needs of future space science missions, and a new type of satellite platform with ultra-high pointing accuracy and ultra-high stability is required

[0005] Through the magnetic levitation mechanism, the space separation between the cabins can be realized, and the micro-vibration effect of the platform cabin can be eliminated, but it is not enough to achieve full physical isolation, and there is still the influence of cables
