Abstract

The invention relates to a wedge-shaped space physical field measurement satellite configuration and an assembly method thereof, and belongs to the technical field of measurement satellites. The satellite configuration comprises a platform service cabin, a wedge-shaped expansion cabin, an extension rod assembly, a vector magnetometer, a scale magnetometer, a Langmuir probe and a thermal ion imager; the platform service cabin is embedded in the wedge-shaped expansion cabin; the extension rod assembly is connected with a platform service cabin top plate and the wedge-shaped extension cabin; thevector magnetometer and the scalar magnetometer are mounted on the extension rod assembly; the Langmuir probe and the thermal ion imager are installed on the platform service cabin; the satellite is of an inner truss main bearing structure combined with the box plate type cabin body to form a truss-supported double-fixed-wing solar cell array structure; a satellite-rocket docking ring is connectedwith a bottom plate of the platform service cabin, and a low-impact locking and unlocking mechanism is installed on an inclined plane of the wedge-shaped expansion cabin. The satellite configurationhas the advantages of sufficient energy supply, small aerodynamic resistance, magnetic cleanness and electric cleanness of the whole satellite, small unfolding impact and high utilization rate of structural space.

Description

technical field [0001] The invention relates to the technical field of measurement satellites, in particular to a configuration of a wedge-shaped space physical field measurement satellite and an assembly method thereof. Background technique [0002] The space physical field measurement satellite used to measure the earth's magnetic field requires magnetic cleanliness, that is, extremely low residual magnetic moment, electric cleanliness, that is, the levitation potential is an order of magnitude lower than that of similar satellites, and the weight is about 200kg. Its payload is more than 4m away from the star, and The pointing accuracy meets the extremely high requirements for load pointing, and the load state determination accuracy is very high. [0003] At present, the existing satellite configurations do not meet such high requirements for magnetic cleanliness and electrical cleanliness due to insufficient consideration of magnetic cleanliness and electrical cleanliness...
