SPORT (Solar Polar Orbit Radio Telescope) clock scanning satellite

Abstract

The invention relates to an SPORT (Solar Polar Orbit Radio Telescope) clock scanning satellite comprising a satellite body, a subsatellite, a stretching arm, a solar cell paddle, a butt-joint ring, a geosynchronous communication antenna and an orbit control engine. The SPORT clock scanning satellite is characterized in that the satellite body is in a cuboid shape and has a three-cabin internal structure; and the subsatellite concretely comprises a subsatellite body, a helical antenna, a reflecting plate, a reflecting plate support frame, a flexible solar paddle, a helical antenna unfolding guide mechanism, a guide unfolding drive motor, a speed reducer, an S wave-band digital antenna, a receiver and a power module. The SPORT clock scanning satellite 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 SPORT clock scanning satellite is provided with an orbit maneuver motor so as to transfer orbits per se when flying during a cruise phase, thereby reducing the requirements on a carrying upper stage; in addition, the SPORT clock scanning satellite ensures the stability of a better satellite attitude through the distribution position of a propelling module of the satellite body.

Description

technical field [0001] The invention belongs to the satellite configuration proposed by the solar polar orbit radio telescope project (SPORT project for short), specifically 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 to the requirements of satelli...

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
