Distribution structure of SPORT (Solar Polar Orbit Radio Telescope) clock scanning satellite

Abstract

The invention relates to a distribution structure of an SPORT (Solar Polar Orbit Radio Telescope) clock scanning satellite. The SPORT clock scanning satellite comprises a satellite body, a subsatellite, a stretching arm, a solar cell paddle, a butt-joint ring, a geosynchronous communication antenna, adopts a main force-bearing structure which is a central force-bearing drum and a radial partition board force-transferring path, has a clear and concise force-transferring link and is beneficial to the design of structure strength and rigidity through configuration distribution; the invention can not cause excessive pressure on the control of a satellite attitude because the distribution position of a propelling module of the satellite body ensures that the position of a satellite geometric center is hardly changed with the decrease of fuel, thereby better keeping the stability of the satellite attitude; in addition, the SPORT clock scanning satellite ensures that relative positions among the earth, the sun and the satellite are changed at any time when the satellite moves on an orbit and the geosynchronous communication antenna is communicated with an earth communication link, and meets the requirements and the limit of carrying, the requirements of payloads on placement, fixing, directions, viewing fields, operation, replacement, thermal control, stability, and the like in a space and the requirements of the payloads on detecting to realize a scientific goal.

Description

technical field [0001] The invention belongs to the satellite configuration proposed by the solar polar orbit radio telescope project (SPORT project for short), and is specifically a layout structure of a SPORT clock scanning satellite. Background technique [0002] The SPORT satellite is a polar-orbiting satellite of the sun. It mainly studies coronal mass ejection events and their propagation and evolution. It will observe the propagation process of the solar wind from the surface of the sun to the earth on the polar orbit of the sun, reveal the propagation law of the solar wind in the sun-earth interplanetary space, and establish and revised interplanetary space weather physical and forecast models. In order to achieve this scientific goal, the SPORT satellite consists of a mother star and 8 sub-stars, which use the clock scanning principle for scientific detection. The 8 sub-stars are respectively fixed on 4 minute hands and 4 second hands. The length varies according t...

Problems solved by technology

[0004] At present, the main technical problems in the configuration and layout design of SPORT satellites are: the satellite is a long-lived satellite, and the orbiting time is relatively long, and the satellite platform must be able to load a large amount of fuel; As the fuel decreases, the stability of the satellite is maintained; how to ensure that the extension arm rod does not couple with the satellite attitude, and the extension arm does not collide with the extension arm; how to realize the clock scanning principle on the satellite platform; when the satellite is in orbit At the same time, the relative positions of the earth, the sun, and the satellite are changing at any time. In order to ensure the communication link with the earth, how to fix the ground communication antenna; how a star is designed
